If it will cause a problem, then it is a problem.
If it will not cause a problem, then it is not a problem.

Simple...

Hi Linda!

 

Gosh, I'm sorry I didn't get these posted earlier. I was planning to as
soon
as I got them, but I got busy doing something else and forgot about your
request. Thanks for reminding me.

 

Anyways, here's your pictures:

I know it's bit of a challenge to find good conformal coat masking tape
that
doesn't leave residues and debris, especially if you bake the boards to
tack
cure the coating.

 

I don't know why Humiseal quit making their tape, it was one of the best
tapes I ever used. But then they just stopped making it for some reason.

Steve,

Could you please post these pictures? We are having problems where there
is
adhesive is sticking to the board when we pull the tape off.

Does anyone know if this would be a problem according to IPC? Would this
be
considered Particulate Matter? Any info will be greatly appreciated.

 

Thanks
