Season's Greets,
A query (actually re-query) to those in the know on the usage of plastic
microcircuits instead of ceramics.
I have some component guys who have ruled that plastic parts can only be
assembled on a no-clean flux line. Anyone using a rosin (RMA) flux is
dis-qualified from assembling for us. I know the theory is that the
microcracks formed at reflow temperatures will entrap corrosive residues,
but I have trouble buying the NO-CLEAN GOOD, ROSIN-BAD generalization.
Opinions?
