Yes, I've seen it recently and it's most likely a component problem. A cap is essentially a sandwich comprised of multiple layers. the layers are either wet film or dry film. The end terminals may either be hot soldered or sputtered so there are a

Hi we are currently experiencing a problem with solder contamination of the gold contact pads on our pcbs following the reflow process, possibly through sputtering. We have been advise that this can be caused due to the pcbs being humid or due to th

Glenn, i am aware of one unique problem with voc free fluxes. since these fluxes have certain amountb of water content they cause sputtering leading to solder balls & voids problems. Regards Vinesh Gandhi | I require some feed back from any one

Any lead free will eat a leaded designed wave soldering machine. But SN100c will eat it the slowest, our soldering tips used to only last 3 months with SAC305 when we changed to SN100c solder wire we are having around 9 months tip life. Our wave sol

I am looking to apply 10-15�m of a conductive material that will withstand 280�C. Our product consists of an alumina substrate sputtered with NiCr (2000�) and Copper (2000�) and 15-60 �m of electroplated copper (all metals patterned on the substrae)

I have a question concerning what plating will go into solution during the reflow process. I am soldering a small piece of ceramic (120x180 mils 7 mil thick) onto a flex circuit. I am seeing some fractures that I am sure are being caused by handlin
