In addition, we all know that HASL is a nasty, dirty, filthy, rotton (fill
in the descriptor of your choice) process and often leaves nasty, dirty
filthy rotton residues behind. It does nasty things to insulation
resistance. If you are going the no-clean route, HASL residues can kill
your product and sometimes, users of your product. By comparison, OSP is a
much cleaner process and does not impact insulation resistance.
Amazing that any planes are still flying or equipment is still functioning
after all
these years of that "nasty" process that has provided adequate product.
