Do you mean "how to solve or reduce this defect at wave soldering process" while continuing to use-up my SACX solder? If so, try: * Smaller solder volumes lower shrinkage hole / hot tears [Higher hole diameter versus pin diameter helps in reducing v

Have you heard about the stamp soldering solution for THT? With a 25 second tact time maximum, for any size board and regardless of the THT component count, and much better yields than a fine tuned SMT process, stamp soldering can remove the largest

We've never seen the defect that you describe, but in wave soldering-land blowholes usually are caused by moisture in the board that out-gasses through the too thin plating of through holes. * Bandaid fix: bake the boards * Long-term fix: Obtain boar

Marcin, Think outside the box. If you are glueing the SMT part down, why not have an aperture cut in your stencil (or recut a stencil) between the SMT part and thru-hole. Wave solder hates SMT glue. This will get rid of your solder short problem

I just reread your message. The wave soldering is on the other side? I.E. The Through hole parts are on the same side as the BGA. This would be the only way to do it. But reading the message again it could be interepted as the through hole parts

Dave: I haven't located something to support your contention, yet, and I'm not going to comment on the factors that drive reliability beyond component selection, because I know that you've got some sweaty-palmed sales type wringing his hands waiting

Hi, The distance between the two terminations/endings/pads of 0603 (0201)is 0.15mm i.e. lesser than than the distance between the 0603 and through hole i.e. 0.5mm My ques is that, then why its termination doesnot short as it has a minimum distance.A
