Technetters- As the industry moves more and more toward SMT, our TH line
continues to mfg mature products. The problem is that as qty rises on SMT,
the qty are dropping on TH. We are seeing older and older parts on the
shelf and would like to avoid solderability problems proactively. I
understand that solderability can vary widely between manufacturers, parts
and lots....but is there an industry standard for how long axial parts can
sit on the shelf (reels in an air conditioned factory, 65-75F, 45-55RH)? I
am looking for a broad guideline (something like: don't use anything older
than X, test parts that are Y-Z, incoming test for new parts). Thanks in
advance. Joe
