So at incoming inspection, what are the results for your "dip & look" solderability testing [IPC/JEDEC J-STD-002A] of the specific problem component?

We've just started running a lot of double sided assemblies. What is the preferred method for removing paste from a board that is populated on side 1 if the side 2 print is poor? Thanks John S.

SnPb No-Clean. We've done it on bare boards with alcohol and an ultrasonic bath, but that seems very agressive on a half populated board. Thanks John S.

I don't know for sure who would have these but would start by asking the used equipment guys that advertise on this forum. Jerry

Check with sigmaprint. They are the origional designer and have an upgrade package. The reason that piece is so expensive is it is a one piece machined stainless steel foil that is 0.010 inch thick. http://www.sigmaprint.co.uk/spares.htm

The ideal and most cost effective solution to this problem is to purchase the FineFoil/CustomFoil retrofit kit that we have designed and can supply. http://www.sigmaprint.co.uk/customfoil.htm

Which nozzles are coming up NG on the large camera? If it's the smaller ones, don't worry about it. Those nozzles don't use the large camera anyways. Be concerned if the small nozzles are coming out NG on the small camera.

The is a serious concern of lead contamination of leadfree solder connections. For background, search the fine SMTnet Archives. For instance: http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=30307
