Hi All!

You're probably wondering; "What the heck? Snake board?" That's what I call
it.

Built this assembly (all PTH), waved it, and then washed it, went to get it
out of our cleaner, and all the solder mask is coming off in big slabs just
like a snake does when he sheds his skin! Go look at "Mask Peel, Mask Peel 2, &
Mask Peel 3" at:

I wash in a Electrovert MCS-1000 with Kyzen XJN, and the mask on the board
was a Dupont Vacrel dry film. Never have had a problem with Vacrel dry films.

The mask doesn't look degraded, or damaged in any way...it's just not stuck
to the board! Anybody ever seen this happen before? Unfortunately, this was a
rather expensive assembly.....:^{

Nice way to start the year off, huh?
