Hi Bob
We specify that the solder mask material must be per a list of materials
we've found work OK. It can be an issue for us - I'd say "it depends"
on how forgiving your coating material is.

Subject: [TN] Conformal coating question part 2
Hi,
I found out I'm calling out a somewhat generic note for my soldermask:
"...APPLY GREEN LIQUID PHOTO IMAGEABLE SOLDER MASK PER IPC-SM-840, CLASS
H..."
Then we are spraying the boards using Tech Spray Fine-L-Kote, 2102,
Silicone Conformal Coating.
Is there a better way to specify my board soldermask that will not cause
compatibility issues with this type of conformal coating?
Or is my concern a non-issue?
Thanks a bunch.
Regards,
Bob Wilson
