We are looking to possibly counterbore a coule of thru holes in one of our PCBs. We would counterbore the top side, and the only trace is coming out of the bottom side. The reason is to mount some LEDs flush with the board. They have some flash wh

Thank for the feedback everyone. The LED is designed to be soldered 2mm above the board, so that is their rational for allowing that much flash. And a spacer is not going to work because of the height limit of mating parts (I didn't design the boar

Thank You Guys for all your input. The reason I raised this case that it was our customer challenge us on the physical outlook of the profile board rather than its functionality no matter the profile curves looks good. Yes, we have a procedure to de

We had the exact same problem in early stages of lead-free. Very random positions of defect + some boards were 100% O.K. and others were an explosion of what I see in your picture. Turned out to be bad processing/materials from board house. I'm do

Thanks, rywman. I do have a solder sample along with dummy BGA's so we should have what we need. This BGA is actually 1152 pins (I didn't have that right in my original post). The bad part is that we are building only one board only and the actua
