Aha, someone else with the same problem. Maybe it is a aqueous problem.
You may have moisture getting up inside the component thru the lead egress.
We had this problem years ago. I am assuming the component is a through
hole leaded device? We cooled down the components prior to aqueous
cleaning.
I think it was 10 to 15 min. Painful but effective. Try this: run
some product through
the process then dry them out in an oven for a few hours at 85deg C, then
retest.
If they test good it is moisture. Why hav you not sent parts to the
manufacturer for
a formal F/A? Do it-put them on the carpet.
Good luck.
