To us, time above liquidous plus 20*C is more important than the 60 sec [er what ever] above 183*C [which we think is meaningless] that the fine solder paste supplier suggest. Based on what you've told us and lacking any failure analysis, we'd gue

Guys When stripping conformal coating from an entire assembly, how do I know the stripping solution won't damage anything on the PCB ? stuff like electronic sensitive devices, wiring, labelling and plastic hinges. And secondly when conformally coati

Best to establish what type of residue is causing this problem and then stamp it out.Speak with SCOPE Labs who offer PCB extraction followed by IR and IC work. So many problems with porous resist at present and NON ionic materials that you really nee

Has anyone had any experience with 60/40 Sn/Ni(300 u in.) over Ni(300 u in.)? If so, what kind of solder issues might exist with 63/37 Sn/Pb reflow? Is a different paste needed? Also, what is the benefit of using the same platings with a top plating

You may struggle finding the information that you seek, because there is so much variability in the design and fabrication of boards. * What is the purpose of such a test? * What product type sees such an use environment? Consider using the guidelin

It is my understanding that per IPC specs toe fillets are not required as they do not add any strength to a solder connection. Our thoughts were allways that proper toe fillets are a sign of a good process. What are some of your guidelines and though
