In the world of PCB manufacturing, even the smallest details can make or break a product’s reliability. One such detail is the PCB solder mask, a protective layer that safeguards your circuit boards from environmental damage, electrical shorts, and soldering errors. For engineers and procurement managers sourcing PCBs for automotive,
Why the insulation solder mask on the board will peel off after the PCB passes the automatic soldering furnace.
There are three major possibilities for solder mask peeling off:
The first possibility is that the nature of solder mask oil is insufficient to withstand the test of solder furnace. This may be due to
Everyone has discussed the circuit board, that what is green layer(solder welding, green oil), what to do (to prevent welding process, solder paste and copper surface contact caused by short circuit)?
First of all, the main component of green oil is resin + green paint. Of course the resin is not green by
