There’s no need to expend time and energy finding the best component costs, going through a frustrating process of procurement and then needing an in-house team to assemble them skillfully. The most significant benefits of turnkey assembly include: <br> <br> <br> <br>Shorter production time <br> <br>As a fundamental form of electronic assembly, PCB assembly primarily contains three phases: PCB fabrication, components procurement and PCB assembly. Traditionally, you should quote and confirm design files with sales and engineers working for your PCB manufacturer, then components distributors and finally PCB assemblers. Such series of quotations and confirmations just need your time spent in contacting with different partners. If those partners are from different countries, you have to overcome some problems such as time zone, communication habits etc. Full-turnkey PCB assembly, however, is a highly-efficient form of electronic assembly. As soon as full-turnkey PCB assembly is determined, an overall assembly quotation and indispensible issues prohibiting smooth manufacturing will be raised so that three times of communication have been cut to one time with electronic assembly efficiency dramatically improved. <br> <br> <br> <br>Cost effective <br> <br>With a turnkey contract, there is no extra cost to deliver freight to an assembly workshop, meaning you save a significant amount of money. Turnkey services also have good working relationships with component manufacturers and can almost always get a better price for parts than small or medium businesses. <br> <br> <br> <br>Issue Identification <br> <br>A major time and money-saving advantage of turnkey PCB assembly is the ability to spot potential issues before the circuit boards make it into any products. As part of the process, you submit a netlist file to the assembler. Before assembly begins, the assembler will check to be sure specifications match the application and identify any errors that may be present. Should any errors be found, you have the opportunity to correct the design and avoid being saddled with thousands of unsuitable circuit boards. <br> <br> <br> <br>Streamlined Management <br> <br>Dealing with multiple vendors can be stressful and a time drain, especially on small businesses with fewer human resources to go around. With turnkey manufacturing solutions, you stand a far less chance of experiencing a miscommunication because you’re managing multiple channels of interaction. These potential miscommunications can happen between you and a vendor, or even between vendors, and can lead to derailment of your timeline and wasted money. <br> <br>Your turnkey supplier will likely provide you with a single point of contact through which all business will be conducted, providing you with peace of mind and lightening the burden of management in the assembly of PCBs. <br> <br> How to obtain a quote for your turnkey pcb electronics ? <br> <br> <br> <br> <br> <br>PCB Online Quote: An Instant PCB price can be quoted base on Board information.

Cleaning equipment: used to clean the PCB after assembly, and remove the residual glue and solder paste. <br> <br>The above are some equipment commonly used in SMT assembly processing, but which equipment and tools need to be used shall be determined according to the actual situation and process requirements. <br> <br> <br> <br>Common inspection methods for Turnkey PCB Assembly processing <br> <br> <br> <br>Our testing and inspection equipment are suitable for simple as well as complex PCB assembly requirements. We can take on extremely demanding projects, and ensure high quality product yield. <br> <br> <br> <br>1. Optical inspection method <br> <br>With the reduction of package size for SMT components and the increase the density for PCB assembly, SMA inspection is becoming more and more difficult, and manual visual inspection is insufficient now, and its stability and reliability are difficult to meet the needs in our production and quality control, so the use of optical inspection is becoming more and more important. <br> <br> <br> <br>2. Artificial visual inspection method <br> <br>This method requires less investment and does not require the programs, but it’s slowly and required directly visual inspect the tested area. Due to the shortcomings of visual inspection, it is rarely used as the mainly quality inspection method in the SMT production line, but most of them are used for repair and rework. <br> <br> <br> <br>3. AOI method <br> <br>Using automated optical inspection as a defect reduction tool, it can be used to find and eliminate errors early in the SMT process for good quality control. AOI adopted advanced vision system, new lighting method, high magnification and complex processing method, so as to obtain high defect capture rate at high test speed. <br> <br>Turnkey PCB Assembly Rework &amp; Repair Guidelines <br> <br> <br>PCBA Boards can be reworked and repaired. However, only reasonable operations based on scientific guidelines can guarantee the quality of PCBA boards; <br> <br>1. PCBA rework and repair basis <br> <br>Rework and repair of PCBA must be performed in accordance with PCB design documents and repair regulations, and there also must be a unified rework and repair process. <br> <br>2. The rework times allowed for each solder joint <br> <br>Rework is allowed for defective solder joints, and rework for each solder joint shall not exceed three times, otherwise it will cause damage to the solder joints. <br> <br>3. Use of removed components <br> <br>In principle, the disassembled components should not be used anymore. If they need to be used, they must be screened and tested according to the original electrical performance and process performance of the components, and the installation is allowed only when they meet the requirements. <br> <br>4. Times of desoldering on each pad <br> <br>Each printed pad should be desoldered only once (that is, only one component is allowed to be replaced). The thickness of the intermetallic compound (IMC) of a qualified solder joint is 1.5~3.5μm, and the thickness will increase after remelting, even when it reaches 50µm, the solder joint becomes brittle, the solder strength decreases... As a result, there are serious reliability risks under vibration conditions. <br> <br>5. Bow and twist requirements for surface mounting and mixed mounting PCBA assembly and soldering <br> <br>The bow and twist of surface mounting and mixed mounting PCBA assembly and welding are less than 0.75%. <br> <br>6. Total times of PCB assembly repairs <br> <br>The total times of repairs for PCB assembly is limited to six; In other words, excessive repairs and modifications affect PCBA reliability. <br> <br>Production requirements for Turnkey PCB Assembly processing <br> <br>1. The production line is set up reasonably and all the labels are correctly posted, warehouse materials and parts should be stored in categories and stacked neatly. <br> <br>2. Product batch management: The defective product control procedure should clearly stipulate the isolation, identification, recording, review and treatment for these defectives. Typically, there should be no more than three times rework for product and no more than twice for component reworks. <br> <br>3. Civilized production: clean, no debris, civilized operation, no brutal and disorderly operation. On-site management must have rules and regulations, inspections, evaluations and records, and carry out &quot;6S&quot; activities every day. <br> <br>4. The maintenance for SMT production line machine and equipment: key equipment should be regularly inspected by special staff, to keep the machine in good condition at all times, we also need to track and monitor the equipment status, and if find problems for machines, we need to take correct solutions to fix and repair it in time. <br> <br> <br> <br> <br> <br>Our full turnkey PCB assembly is a highly-efficient and fast form of electronic assembly.

What is the LED Circuit Board assembly? <br> [email protected] <br> <br>Generally, LED PCB assembly is considered to be a circuit board that has the LED components soldered to it. The LED is soldered to the printed circuit board and features a chip that creates the light as electrically connected. A thermal heat sink and a ceramic base are used to bond the chip. Not all the PCB products can be used in Led industry, as an LED PCB is easy to create a high volume of heat, but making it hard to cool with traditional methods. For this reason, metal core PCB is widely used in LED application because of their enhanced ability to dissipate heat, especially aluminum pcb is often used to fabricate PCB for LED lights. <br> <br>We’ve had great LED PCB assembly experiences with top LED chips to brand such as Cree, Luxeon, Osram, Nichia, Lumileds, MLS, EVERLIGHT, Samsung, LG, Seoul., etc. PCB LED lights can be incorporated into numerous lighting applications due to their combination of excellent energy efficiency, low cost and maximum design flexibility. <br> <br>Application of LED PCB Assembly <br> <br> <br>Hitechpcba serves customers in different industries, providing highly reliable and innovative LED PCBs for various applications: <br> <br>• Horticulture light LED PCB Assembly <br> <br>• LED controller PCB Assembly <br> <br>• Computer LED display and indicators <br> <br>• LED lights PCB Assembly for medical use <br> <br>• Automotive LED PCBs Assembly include PCBs for brake lights and headlights <br> <br>• Street lighting LED PCB Assembly <br> <br>• Flashlights and camping accessories <br> <br>• Traffic light PCB Assembly <br> <br>• Commercial lighting LED PCB Assembly <br> <br> <br> <br> <br> <br>LED PCB Assembly specification <br> <br> <br>Number of layers for LED PCB <br> <br>These layers are made up of aluminum and magnesium, but now have Copper base material and Ceramic base materials for LED PCB industry, we can meet it. <br> <br>Aluminum LED PCBs stand out among other PCBs because it has a good insulation characteristic and has a better machinery performance, the cheap cost is one important factor too. <br> <br> <br> <br>Types of layers for LED PCB Assembly <br> <br>Normally, the base layer is made using aluminum alloy metal. <br> <br> <br> <br>This aluminum alloy substrate used in making the base makes it ideal for through-hole technology which transfers and dissipates heat. <br> <br> <br> <br>A thermal insulation layer is made using some ceramic polymer which has good viscoelasticity characteristics. <br> <br> <br> <br>It is highly heat resistant and protects the PCB against heat and mechanical stress. <br> <br> <br> <br>The circuit layer, which is covered by a copper foil which can range from one to ten ounces. <br> <br> <br> <br>LED Board type- single or in panel <br> <br>Some boards are shapeless. For this reason, LED PCB panels are used. This reduces time, labor production and testing time. <br> <br> <br> <br>Some LED PCB Assembly is done on a single board while others are done on panel boards. <br> <br>LED PCB Assembly Process <br> <br> <br>Roughly, the PCBA process can be divided into theses phases: soldering paste printing &gt; SMT (surface mounted technology) &gt; reflow soldering &gt; AOI (automated optical inspection)&gt; THT (through-hole technology) &gt; wave soldering &gt; touch-up and cleaning &gt; IC-programming &gt; FCT (functional tests) &gt; aging testing. <br> <br>Below we show you the process. <br> <br> <br> <br>Step1. Summarizing Project Information <br> <br>Before contacting your supplier, make sure you have all the project information. Suppliers will need info following for quoting LED PCB assembly: <br> <br> <br> <br>Gerber <br> <br>BOM <br> <br>LED PCB specification <br> <br>Quotation quantity <br> <br>Once you have gathered these information, you can contact us and request for a quote. <br> <br>Of course, you can also provide the schematic, LED PCB Assembly pictures and even samples to us. The more details they have, the more accurate the supplier’s quotation will be. <br> <br> <br> <br>Step2. Discussion and details about custom LED PCB Assembly <br> <br>Different projects will have different requirements. Remember the special requirements mentioned in step 1? That’s going to be the focus of this session. Equipment and engineering capacity will not be identical between suppliers. Make sure your supplier has the equipment to produce and assemble major components and the corresponding testing capabilities. <br> <br> <br> <br>For example, some vendors don’t have X-ray testing equipment, which means they can’t check the mount quality of BGA chips. Outsourcing this step will increase risk and cost. That’s what you don’t want. <br> <br> <br> <br>Also, pay attention to time taken by the supplier to quote. Motherboards often contain hundreds or even thousands of components, and they are supplied by different manufacturers. To ensure the quality of the components, the supplier sourcing team will make multi-inquiries from these manufacturers or authorized suppliers to match customer’s requirement, which usually takes 2-3 business days, and even longer for some scarce chips. Therefore, if your project is complex and the supplier quotes you within few hours, double check with them. <br> <br> <br> <br>Step3. Sample and feedback <br> <br>After confirming the PI, the supplier will usually provide pre-production samples for your approval. At the same time, the supplier will also confirm with you the logistics plan of the bulk goods. Make sure they understand your shipping requirements, including details on packaging, customs clearance, taxes, etc. <br> <br> <br> <br>For us to have a successful LED PCB Assembly process, its functions must be defined. Compliance requirement is defined to reduce the effect when components are selected. <br> <br>The Bill of Materials is then generated from the information installed on the LED PCB. <br> <br>All this information is used to assemble components which are identified from MOB to the LED PCB. <br> <br>After that, the routing of traces is determined to each component, based on the size, shape of the circuit board and location of connectors. <br> <br>Hitech Circuits is trusted by thousands of electronic engineers on their LED PCB assembly projects, from consumer, led bulb to precisely medical LED light, we can help you from the beginning of design stage; From commercial flood LED to industrial high power LED, from automotive LED to military LED, Venture is the perfect place for your LED PCB assembly requirement. <br> <br> <br> <br>Hitech Circuits has been participated in hundreds and thousands of LED lighting projects, by providing LED PCB and also LED PCB assembly service. <br> <br> <br> <br>Our LED PCB assembly had covered both ends of the Lighting Class LED size spectrum, assembling some of the largest (2 meter long boards) and some of the smallest LED Lighting applications which used in Medical Endoscopes. <br> <br> <br> <br>LED PCB Assembly is very crucial in the current industrial development. Many electrical devises are being innovated and the old once being improved. <br> <br>LED PCBs are useful due to the fact that they are made using materials that can transfer and dissipate heat.

Our team of procurement specialists scours their sources to locate the exact parts you’re looking for, at the best price available on any given day. <br> <br> <br> <br>The Benefits of Turnkey PCB Assembly Manufacturing <br> <br>The most obvious benefit of turnkey PCB assembly is that businesses don’t have to take their focus off critical processes like continual innovation to spend time figuring out the assembly side. There’s no need to expend time and energy finding the best component costs, going through a frustrating process of procurement and then needing an in-house team to assemble them skillfully. The most significant benefits of turnkey assembly include: <br> <br> <br> <br>Shorter production time <br> <br>As a fundamental form of electronic assembly, PCB assembly primarily contains three phases: PCB fabrication, components procurement and PCB assembly. Traditionally, you should quote and confirm design files with sales and engineers working for your PCB manufacturer, then components distributors and finally PCB assemblers. Such series of quotations and confirmations just need your time spent in contacting with different partners. If those partners are from different countries, you have to overcome some problems such as time zone, communication habits etc. Full-turnkey PCB assembly, however, is a highly-efficient form of electronic assembly. As soon as full-turnkey PCB assembly is determined, an overall assembly quotation and indispensible issues prohibiting smooth manufacturing will be raised so that three times of communication have been cut to one time with electronic assembly efficiency dramatically improved. <br> <br> <br> <br>Cost effective <br> <br>With a turnkey contract, there is no extra cost to deliver freight to an assembly workshop, meaning you save a significant amount of money. Turnkey services also have good working relationships with component manufacturers and can almost always get a better price for parts than small or medium businesses. <br> <br> <br> <br>Issue Identification <br> <br>A major time and money-saving advantage of turnkey PCB assembly is the ability to spot potential issues before the circuit boards make it into any products. As part of the process, you submit a netlist file to the assembler. Before assembly begins, the assembler will check to be sure specifications match the application and identify any errors that may be present. Should any errors be found, you have the opportunity to correct the design and avoid being saddled with thousands of unsuitable circuit boards. <br> <br> <br> <br>Streamlined Management <br> <br>Dealing with multiple vendors can be stressful and a time drain, especially on small businesses with fewer human resources to go around. With turnkey manufacturing solutions, you stand a far less chance of experiencing a miscommunication because you’re managing multiple channels of interaction. These potential miscommunications can happen between you and a vendor, or even between vendors, and can lead to derailment of your timeline and wasted money. <br> <br>Your turnkey supplier will likely provide you with a single point of contact through which all business will be conducted, providing you with peace of mind and lightening the burden of management in the assembly of PCBs. <br> <br> How to obtain a quote for your turnkey pcb electronics ? <br> <br> <br> <br> <br> <br>PCB Online Quote: An Instant PCB price can be quoted base on Board information. Full turnkey assembly cost: This is an additional instant quote for the cost of labor for Turnkey PCB assembly. BOM Pricing: To get a BOM price within 24 hours, email the BOM to [email protected] and include all details such as quantities, reference designators, and Parts manufacturer name and part number. Most entrepreneurs and manufacturers find the old ways of manufacturing electronics and to printed circuit board assembly very intimidating because it is slow, prone to errors, and expensive. It wasn’t designed for small batch runs and prototypes, but to support enormous orders with a long lead time. Luckily, the services of Turnkey Printed Circuit Board (PCB) assembly are coming in today to meet the needs of hardware designers <br> <br> <br> <br> <br> <br>Precautions during Turnkey PCBA processing <br> <br> <br> <br>PCBA is the abbreviation of Printed Circuit Board Assembly, which is an important link in the manufacturing process of electronic equipment.

Encapsulation stage <br> <br>In the packaging stage of PCBA processing and production process, the following points need to be paid attention to: <br> <br>(1) Selection of packaging materials: The selection of packaging materials needs to be determined according to the performance requirements of the product and the use environment, such as high temperature resistance, heat resistance, dust resistance, etc. <br> <br> <br> <br>(2) Temperature and time control during the packaging process: During the packaging process, it is necessary to pay attention to the control of temperature and time, so as to avoid the failure of packaging materials or the degradation of product performance due to excessive temperature or too long time. <br> <br>(3) The sealing of the package: the sealing of the package is very important to the stability and reliability of the product, and it is necessary to ensure the sealing during the packaging process. <br> <br> <br> <br>4. Testing phase <br> <br>In the testing phase of the PCBA processing and production process, the following points need to be paid attention to: <br> <br>(1) Selection of testing instruments and equipment: The selection of testing instruments and equipment needs to be determined according to the performance and specifications of the product to ensure the accuracy and reliability of the test results. <br> <br>(2) Setting of test parameters: The setting of test parameters needs to be determined according to the performance requirements and specifications of the product to ensure the accuracy and reliability of the test results. <br> <br>(3) Judgment and recording of test results: The judgment and recording of test results need to be carried out in strict accordance with product testing standards to ensure the accuracy and reliability of test results. <br> <br> <br> <br>Briefly, in the PCBA processing and production process, we need to pay attention to the details of each link, so as to ensure the quality and reliability of the product. In the manufacturing process, it is necessary to strictly follow the design requirements and manufacturing standards, follow good manufacturing specifications and quality management systems, and finally achieve high-quality, high-efficiency PCBA processing and production. <br> <br> <br> <br> <br> <br>Common machines for Turnkey SMT processing <br> <br>1. SMT machine: It is used to accurately place the components on the PCB, including automatic surface mounting machines, semi-automatic surface mounting machines and manual mounting machines. <br> <br>2. Hot air soldering equipment: including hot air guns and reflow soldering ovens etc., it used to solder SMT components on PCBs. <br> <br>3. SMT component storage rack: used to store and organize SMT components. <br> <br>4. 3D AOI inspection equipment: used to check the placement and quality of SMT components. <br> <br>5. Coating equipment: including automatic coating machine and manual coating machine, etc., used to coat the glue on the surface of PCB. <br> <br>6. Solder paste printing machine: used to print solder paste on PCB for use in subsequent soldering process. <br> <br>7. Wave soldering equipment: used for soldering DIP components, such as connectors, sockets, etc. <br> <br>8. Cutting machine: used to cut the PCB after patch into a single board. <br> <br>9. Cleaning equipment: used to clean the PCB after assembly, and remove the residual glue and solder paste. <br> <br>The above are some equipment commonly used in SMT assembly processing, but which equipment and tools need to be used shall be determined according to the actual situation and process requirements. <br> <br> <br> <br>Common inspection methods for Turnkey PCB Assembly processing <br> <br> <br> <br>Our testing and inspection equipment are suitable for simple as well as complex PCB assembly requirements. We can take on extremely demanding projects, and ensure high quality product yield. <br> <br> <br> <br>1. Optical inspection method <br> <br>With the reduction of package size for SMT components and the increase the density for PCB assembly, SMA inspection is becoming more and more difficult, and manual visual inspection is insufficient now, and its stability and reliability are difficult to meet the needs in our production and quality control, so the use of optical inspection is becoming more and more important. <br> <br> <br> <br>2. Artificial visual inspection method <br> <br>This method requires less investment and does not require the programs, but it’s slowly and required directly visual inspect the tested area. Due to the shortcomings of visual inspection, it is rarely used as the mainly quality inspection method in the SMT production line, but most of them are used for repair and rework. <br> <br> <br> <br>3. AOI method <br> <br>Using automated optical inspection as a defect reduction tool, it can be used to find and eliminate errors early in the SMT process for good quality control. AOI adopted advanced vision system, new lighting method, high magnification and complex processing method, so as to obtain high defect capture rate at high test speed. <br> <br>Turnkey PCB Assembly Rework &amp; Repair Guidelines <br> <br> <br>PCBA Boards can be reworked and repaired. However, only reasonable operations based on scientific guidelines can guarantee the quality of PCBA boards; <br> <br>1. PCBA rework and repair basis <br> <br>Rework and repair of PCBA must be performed in accordance with PCB design documents and repair regulations, and there also must be a unified rework and repair process. <br> <br>2. The rework times allowed for each solder joint <br> <br>Rework is allowed for defective solder joints, and rework for each solder joint shall not exceed three times, otherwise it will cause damage to the solder joints. <br> <br>3. Use of removed components <br> <br>In principle, the disassembled components should not be used anymore. If they need to be used, they must be screened and tested according to the original electrical performance and process performance of the components, and the installation is allowed only when they meet the requirements. <br> <br>4. Times of desoldering on each pad <br> <br>Each printed pad should be desoldered only once (that is, only one component is allowed to be replaced). The thickness of the intermetallic compound (IMC) of a qualified solder joint is 1.5~3.5μm, and the thickness will increase after remelting, even when it reaches 50µm, the solder joint becomes brittle, the solder strength decreases... As a result, there are serious reliability risks under vibration conditions. <br> <br>5. Bow and twist requirements for surface mounting and mixed mounting PCBA assembly and soldering <br> <br>The bow and twist of surface mounting and mixed mounting PCBA assembly and welding are less than 0.75%. <br> <br>6. Total times of PCB assembly repairs <br> <br>The total times of repairs for PCB assembly is limited to six; In other words, excessive repairs and modifications affect PCBA reliability. <br> <br>Production requirements for Turnkey PCB Assembly processing <br> <br>1. The production line is set up reasonably and all the labels are correctly posted, warehouse materials and parts should be stored in categories and stacked neatly. <br> <br>2. Product batch management: The defective product control procedure should clearly stipulate the isolation, identification, recording, review and treatment for these defectives. Typically, there should be no more than three times rework for product and no more than twice for component reworks. <br> <br>3. Civilized production: clean, no debris, civilized operation, no brutal and disorderly operation. On-site management must have rules and regulations, inspections, evaluations and records, and carry out &quot;6S&quot; activities every day. <br> <br>4. The maintenance for SMT production line machine and equipment: key equipment should be regularly inspected by special staff, to keep the machine in good condition at all times, we also need to track and monitor the equipment status, and if find problems for machines, we need to take correct solutions to fix and repair it in time. <br> <br> <br> <br> <br> <br>Our full turnkey PCB assembly is a highly-efficient and fast form of electronic assembly.

LED PCB Manufacturer &amp; Assembly – One-stop service

What is the LED Circuit Board assembly? <br> [email protected] <br> <br>Generally, LED PCB assembly is considered to be a circuit board that has the LED components soldered to it. The LED is soldered to the printed circuit board and features a chip that creates the light as electrically connected. A thermal heat sink and a ceramic base are used to bond the chip. Not all the PCB products can be used in Led industry, as an LED PCB is easy to create a high volume of heat, but making it hard to cool with traditional methods. For this reason, metal core PCB is widely used in LED application because of their enhanced ability to dissipate heat, especially aluminum pcb is often used to fabricate PCB for LED lights. <br> <br>We’ve had great LED PCB assembly experiences with top LED chips to brand such as Cree, Luxeon, Osram, Nichia, Lumileds, MLS, EVERLIGHT, Samsung, LG, Seoul., etc. PCB LED lights can be incorporated into numerous lighting applications due to their combination of excellent energy efficiency, low cost and maximum design flexibility. <br> <br>Application of LED PCB Assembly <br> <br> <br>Hitechpcba serves customers in different industries, providing highly reliable and innovative LED PCBs for various applications: <br> <br>• Horticulture light LED PCB Assembly <br> <br>• LED controller PCB Assembly <br> <br>• Computer LED display and indicators <br> <br>• LED lights PCB Assembly for medical use <br> <br>• Automotive LED PCBs Assembly include PCBs for brake lights and headlights <br> <br>• Street lighting LED PCB Assembly <br> <br>• Flashlights and camping accessories <br> <br>• Traffic light PCB Assembly <br> <br>• Commercial lighting LED PCB Assembly <br> <br> <br> <br> <br> <br>LED PCB Assembly specification <br> <br> <br>Number of layers for LED PCB <br> <br>These layers are made up of aluminum and magnesium, but now have Copper base material and Ceramic base materials for LED PCB industry, we can meet it. <br> <br>Aluminum LED PCBs stand out among other PCBs because it has a good insulation characteristic and has a better machinery performance, the cheap cost is one important factor too. <br> <br> <br> <br>Types of layers for LED PCB Assembly <br> <br>Normally, the base layer is made using aluminum alloy metal. <br> <br> <br> <br>This aluminum alloy substrate used in making the base makes it ideal for through-hole technology which transfers and dissipates heat. <br> <br> <br> <br>A thermal insulation layer is made using some ceramic polymer which has good viscoelasticity characteristics. <br> <br> <br> <br>It is highly heat resistant and protects the PCB against heat and mechanical stress. <br> <br> <br> <br>The circuit layer, which is covered by a copper foil which can range from one to ten ounces. <br> <br> <br> <br>LED Board type- single or in panel <br> <br>Some boards are shapeless. For this reason, LED PCB panels are used. This reduces time, labor production and testing time. <br> <br> <br> <br>Some LED PCB Assembly is done on a single board while others are done on panel boards. <br> <br>LED PCB Assembly Process <br> <br> <br>Roughly, the PCBA process can be divided into theses phases: soldering paste printing &gt; SMT (surface mounted technology) &gt; reflow soldering &gt; AOI (automated optical inspection)&gt; THT (through-hole technology) &gt; wave soldering &gt; touch-up and cleaning &gt; IC-programming &gt; FCT (functional tests) &gt; aging testing. <br> <br>Below we show you the process. <br> <br> <br> <br>Step1. Summarizing Project Information <br> <br>Before contacting your supplier, make sure you have all the project information. Suppliers will need info following for quoting LED PCB assembly: <br> <br> <br> <br>Gerber <br> <br>BOM <br> <br>LED PCB specification <br> <br>Quotation quantity <br> <br>Once you have gathered these information, you can contact us and request for a quote. <br> <br>Of course, you can also provide the schematic, LED PCB Assembly pictures and even samples to us. The more details they have, the more accurate the supplier’s quotation will be. <br> <br> <br> <br>Step2. Discussion and details about custom LED PCB Assembly <br> <br>Different projects will have different requirements. Remember the special requirements mentioned in step 1? That’s going to be the focus of this session. Equipment and engineering capacity will not be identical between suppliers. Make sure your supplier has the equipment to produce and assemble major components and the corresponding testing capabilities. <br> <br> <br> <br>For example, some vendors don’t have X-ray testing equipment, which means they can’t check the mount quality of BGA chips. Outsourcing this step will increase risk and cost. That’s what you don’t want. <br> <br> <br> <br>Also, pay attention to time taken by the supplier to quote. Motherboards often contain hundreds or even thousands of components, and they are supplied by different manufacturers. To ensure the quality of the components, the supplier sourcing team will make multi-inquiries from these manufacturers or authorized suppliers to match customer’s requirement, which usually takes 2-3 business days, and even longer for some scarce chips. Therefore, if your project is complex and the supplier quotes you within few hours, double check with them. <br> <br> <br> <br>Step3. Sample and feedback <br> <br>After confirming the PI, the supplier will usually provide pre-production samples for your approval. At the same time, the supplier will also confirm with you the logistics plan of the bulk goods. Make sure they understand your shipping requirements, including details on packaging, customs clearance, taxes, etc. <br> <br> <br> <br>For us to have a successful LED PCB Assembly process, its functions must be defined. Compliance requirement is defined to reduce the effect when components are selected. <br> <br>The Bill of Materials is then generated from the information installed on the LED PCB. <br> <br>All this information is used to assemble components which are identified from MOB to the LED PCB. <br> <br>After that, the routing of traces is determined to each component, based on the size, shape of the circuit board and location of connectors. <br> <br>Hitech Circuits is trusted by thousands of electronic engineers on their LED PCB assembly projects, from consumer, led bulb to precisely medical LED light, we can help you from the beginning of design stage; From commercial flood LED to industrial high power LED, from automotive LED to military LED, Venture is the perfect place for your LED PCB assembly requirement. <br> <br> <br> <br>Hitech Circuits has been participated in hundreds and thousands of LED lighting projects, by providing LED PCB and also LED PCB assembly service. <br> <br> <br> <br>Our LED PCB assembly had covered both ends of the Lighting Class LED size spectrum, assembling some of the largest (2 meter long boards) and some of the smallest LED Lighting applications which used in Medical Endoscopes. <br> <br> <br> <br>LED PCB Assembly is very crucial in the current industrial development.
