Hi Michael,

We use TempSeal DA on assemblies prior to wave flow soldering.
We cover hardware, fill in holes and tack down packages known to float.

The down side time: application and drying and removal afterwards. We've
thought of looking into a water soluble mask that will get washed off when
we clean the assemblies.

I'm also looking into pallet templates to eliminate the masking operation
all together, on at least one assembly.

Hans

Subject: [TN] Peelable SolderMask


Any manufacturers in here have experience with peelable mask? Only the good
points are ever discussed in the sales brochures. I'm looking for the evil
side. It seems to go against everything I've ever tried to accomplish with a
solder mask and it makes me a little nuts to think a customer wants to undo
what we try so hard to do! I'm afraid next they'll want removable
traces.....Any thoughts or comments appreciated.
