Hi Lloyd,

I'm sorry I didn't make it clear. I'm referring to water soluble masks
before wave solder, not conformal coating....

Tough to put into practice. With masking you want to get the masking
material off before the coating has completely cured to minimize lifting
and peeling. The washing machine could damage that uncured coating. Plus
the coating is covering the masking so the water will not touch the
masking to dissolve it until the coating is removed from it first. I
tried it with parylene and we had to pick holes in the film so the water
could access the masking then go back and trim off the excess after the
masking dissolved and we were left with a "tent" of film

Re-usable boots are ideal but could be costly when you have many
different style/sizes of connectors.

Like we tell all our customers, cheapest way to coat something is leave
off all the connectors!!
