Please check with Fab house, what is the thickness of the immersion gold if the gold thicknesss is less than say 2.5 micron, you will found dewetting or open. It is recommend the gold thickness is around 5 micron. Good Luck Dason

This "thieving" idea is a good one. There is a SMTnet thread on connector thiefs from a coupla years ago that you might check.

John makes good points that are in line with those made [in the SMTnet Archives] when trying to solve solder side bridging problems in SOIC and such.

BGA Manufacture and process control. To X-ray or not to X-ray, that is the question!!! Are there any bench top or sample inspection units avaliable with good(useable) software?? Help me SMT netters, you are my only hope. Marc

George and the others make good points. Check Les Hymes response to a similar question in 7/00 "Circuits Assembly"

1. It is hard to tell, but your PCB vendor should test the PCB. 2. I think the important thing is the width of the apertures. You should have it laser-cut, and control the width no more than 90% of half pitch. Good luck.

CJ: Arturo and the others make good suggestions. Consider: IPC-7525 Stencil Design Guidelines

Hi, Instead of using High Temp solder, I would like to use a UV epoxy to atach termocouples to reflow profile boards. Does any one know a good one? Thanks in advance. Alberto
