I wouldn't raise the temps just slow the conveyor, You need to get the PCB "soaked in". It seems as if you are applying more thermal energy than the PCB can accept in all areas. Does this oven have convection heating? Hopefully so. I have found t

Thanks Mr.Dave. Sorry for the delay. One of our major prolems in ENIG plated surface is that wire does not stick. For many years we were getting a bond strength of 14 grams in both ENIG and electroplated surfaces. Now one vendor supplies ENIG boards

We been using the Sayaka SAM-CT23Q machine to depanel PCB, it was fine. But now, we have to depanel the Aluminum PCBs the current bits from IMPEC we are using are not strong enough (1.5x8.0 diamond downcut). Need to find much strong bit or bits des

Can you post pictures here ? It should be quite straightforward to solve.

I'm having trouble picturing your setup, but can you put kapton on the columns? Or heat shrink tubing?
