Yes, they do the cleaning, we did the (apparently first) inspection and caught the problems. They tried a shorter cleaning cycle, witnessed no defects, and attributed the defects on the boards we had to their cleaning process. Now they just plan on

There are several types of lasers to do laser soldering. Panasonic also has a high intensity light that can solder as well. I've tried em' all and two over whelming things stand out when it comes to this type of soldering. #1 is preheat. It seems

Paul, I have (as many have) come across this problem due to misregistration of resist at the PCB fab. You didn't say if these boards are inexpensive double sided or costly multis. I know this shouldn't make a difference on quality but I would tend t
