As an engineer in the electronics manufacturing industry, have you ever encountered the need to rework a printed circuit board (PCB) to remove the solder mask? If so, how did you approach this problem?
Traditionally, the solder mask is manually removed using a knife or hand grinding tool. However, this method often results in damage to the traces on the PCB, leading to a high scrap rate for both the PCB and PCB assembly.
WorkingBear would like to introduce a new method of removing the solder mask using a laser machine, which is highly efficient and reliable. By selecting the appropriate laser power, the solder mask can be removed without damaging the copper underneath. read more…》
