Celiav: Mark is probably spot-on on his comments about a board fab problem. It is weird that you have similar problems from two suppliers though. Recommendations are: � Get rid of any bird brain contractor that installs processes that affect your

Larry: I've got extensive experience with solder skips on both 0603 and SOT23 devices. We also installed an "Omega" vibrating wave on our machine, but it didn't really have an impact on solder skips. The major difference that the omega makes is in

Dreamsniper, The optimum contact (dwell) time in the wave should be 2 seconds. Contact band width is a function of conveyor speed. For an example, 5cm of contact band width at 150cm/min. conveyor speed will give you 2 seconds of contact time and 2cm

| | Hi, | | We are having problem with yield loss due to electrical fail. Further investigation shows that the failure is due to solder bridging under BGA. Has been there any study or experience on how this could occur and what we can do to prevent

| | I have gold fingers that I want to mask when running over the wave without pallets. They're on the leading edge of the board. I recall seeing rubber boots that slid onto the fingers to mask them. Pop 'em on before the wave; pop' em off after a
