Via In Pad Fr4 PCB

Via In pcb board material fr4, using copper plating or epoxy to fill holesfor circuit board factor, prevent solder paste or flux from flowing into the via in pad, avoid solder ball getting into via or solder mask cover on pad and cause false soldering. HUIHE CIRCUITS Via In Pad Fr4 PCB has passed ISO9001/ISO13485/IATF16949/UL/RoHS/REACH certification.

What Is A Hole-In-The-Panel Circuit Board?
The hole in the disk is an important part of the multi-layer PCB. It is not only responsible for the main functions of the PCB, but also the cost of drilling usually accounts for 30% to 40% of the PCB manufacturing cost. In short, the holes pressed on the pads on the PCB can all be called holes in the disk.

Processing Requirements For Hole Plugs In The Disk
No solder mask ink entering the hole
There should be no tin beads hidden in the hole
No explosive oil, ink pads, making it difficult to mount components, etc.

Common Sense Of Circuit Board Plug Hole
Prevent the tin from penetrating the component surface from the via hole to cause a short circuit when the PCB is wave soldered
Avoid flux residue in the vias
Prevent the tin balls from popping up during wave soldering, causing short circuits
Prevent surface solder paste from flowing into the hole, causing false soldering and affecting placement
