Our company is the production of batteries, we weld two solder joints on the PCM, but in some components have a solder joint, with welding explosion phenomenon, but the welding on the battery is normal, what is the reason causing the solder joint in other places splash, please Bobo
It is possible that the laser frequency is too high to lower the level

The description of the problem is a bit simple. Does that extra solder joint look normal? Splash or real solder joint? Does each welding occur? Do you use an ordinary table or a mirror table? Is laser triggered by level or pulse?
