At Nepcon west 1999, Al Schneider presented some work I did on Paralene
and no-clean soldering materials with disappointing results. If anyone
wants a copy, email me.

We recently had some issues with lack of adhesion of Parylene coating
What types of notes are being used on drawings to define parylene
conformal coating adhesion test on pwa's?
Is the ASTM3359-08 (for assessing the adhesion of coating films to
metallic substrates) the best spec to call out for this testing .
I presently don't have pwb coupons to perform destructive cross hatch
test.
What type of tape is being used testing parylene adhesion on the PWA's?
Some specs call out 3M-250 tape, the ASTM D 3359 calls out the Permacel
99.
Actually I prefer the Wescorp 79210 clear Anti-static Tape, does this seem
acceptable?
