"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."
Humiseal never made the tape. They procured it from St. Gobain and
renumbered it with their own part number. St. Gobain had severe production
issues with this tape and as such Humiseal got tired of dealing with it.
There was a company in Florida that was cutting it for them, but he tripled
his prices so we found another supplier.
The part number is M797 from St. Gobain and is still readily available from
various suppliers. We get ours from http://www.robertmckeown.com/ Just be
sure to tell them to cut it without silicone.

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
