Can anyone offer guidelines on DFM and process recommendations for soldering .050" pitch connectors in the wave. The initail design had .026" drill with .043" pads so only .007" between pads. I requested .035" pads, but this still only leaves .015" b

Slump is a function of the particular paste you select and the temperature of the paste. Use a slump test like the one that follows to compare fluxes. Slump Test Step Process activity 1 Print paste on white ceramic substrate or microscope sli

I was wondering IF anybody has has success wave soldering a 50 (2 rows of 25) pin 0.050" pitch thru-hole connector. I seem to be getting alot of bridging no matter what I do. Is there a design spec for the size and shape of pads? The pads on the pcb

This works for me with ENIG finish and a SAC305 NC paste Reduce all pads by -2mil on all sides ie 0.050" x 0.050" becomes 0.046" x 0.046" EXCEPT Anything smaller than 30mil; -1.5mil Anything smaller than 20mil; -1mil Anything smaller than 15mil;

Hi Ed, It all depends on your BGA, your placement eqmt, your inspection method and your rework station. I would keep pasrts 0.050" away fromt eh part if possble. I would X-Ray inspect the part, so parts being close really wouldn't be a factor. Fo

I can't help you with your soldering problem, but I wonder if a pressfit connector is an option for you. If this connector is available as pressfit, you can avoid the solder wave proces and associated problems. Write me if you are interested in more
