"Gap" in completed solder joint between lead and pad

Electronics Forum | Tue Nov 28 09:21:58 EST 2006 | Michael Sanders

Is anyone aware of any articles, white papers, etc., that discuss the gap between the lead and the pad after a SM joint is soldered? In particular, I am looking for a formula for that "gap" for various components.

IPC 610 *C* states that the solder thickness requirement is a properly wetted termination is evident. Fillet height is another aspect and is usually specific to the package but is some function of solder thickness plus a percentage of lead height. D

Your customer is so poorly educated that you should decline their work, because this will not be the last time they waste your time with their cockamamey theories.

Does anyone know why there would be magnets on the bottom of the locating plate on a CP6 feeder ? We seem to have some feeders with them and some without.

For the criminally insane to help them locate the feeders? Or to help hold them down when changing them if you don't have those huge lumps of steel they clip into?

I am starting to use a DATAPAQ wave analysis software on our Econopak EPK II machines. I would like to know what values you may be using for alarm conditions. I can email an example if you can help. Thanks
