Superflo 26F is a no-clean flux, I bet your trying to wash it in water. You could not clean the board that flux will not hurt it at all, that is unless your conformal coating it. You could also run a simi-aqueous wash or maybe a saponifier in your wa

It has been our experience that the problem you have discribed was not solder process related. We had two such instances in the past and both were component related. The first case involved a PLCC28 that failed test. Reflowing the solder seemed to co

Compared to paper tape, I find a higher defect rate on 0402 components in plastic tape even without the PSA tape. The plastic tape appears to be less shock absorbent and this may be the reason for feeding problems on small components. PSA tape has it

I am trying to find the plastic family used in manufacturing the bodies of integrated circuits. Usually our product is fully encapsulated in ScotchCast however a new application requires part of a pressure sensor chip to be free of encapsulant. The S

Point well taken John. Expanding on epoxies: Novolac is a multifunctional epoxy ... a phenolic resin. Most phenolic resins are made using phenol (P) and formaldehyde (F). They comprise the bulk of IC packaging and are divided into two classes:
