I have used tooling holes and fiucial registration since the late '80's. In fact if your maximum "vision" tolerance is +/- 0.05mm, your in the same ball-park as locating pins. It is true that fiducial registration is more accurate. However, I woul

M.L. Feather- You may be better off using a square (rectangle) SMT pad instead of a Router hole. Since all the placement data will be referenced off the "fid" you use - placement problems could happen if Router holes are used as the router path can v

Adam, Is your fluxer giving you good coverage into the holes and to the top of the board? If your hole size in relation to the lead diameter is too small, this may be contributing. I'd check your fluxing first though. Just an aside.....We just sw

Folks, At the moment I bake all BGA that are in unsealed trays, to reduce moisture etc. Is this common practice or are there particular manufacturuers that cause more problems. Also, the tape for BGA tape & reel has a hole in the tape (as is normal

Russ, We can not use a wave pallet, already went that route. We have parts next to the thru-hole pins and between thru-hole pins. I am going to try an experiment in the next day or so with solder mask. I plan to solder SMT parts on the back of se

We don't have any automated machines (UIC) that insert anything into holes larger than our terminals, so about 0.050" is as big a hole we ever have to use before we've plugged them with something. Since we also do a fair amount of Man-U-Sert (yes, yo

Did you get your answer? From all the reading I've done since your posting, does this issue happen when running a "specific" program or any/all programs ? Just a thought, as MOD codes can be tricky. Also check the thru-holes on that backplain conn th

On the non-wetted holes put a solder iron to them and see if they "bubble" if so, you have some outgassing in your PCB and they will need to be baked prior to assembly. If this is okay I would investigate the grnd layer that was mentioned. What is
