I have used Wondermask from Techspray, #2207-p. It is billed as a screenable
water soluble mask. I used a standard stencil, .005" thick, after curing for
30 min at 150F the solder paste was stenciled onto the assembly. After
reflow the assemblies were washed and the I/O pins hand soldered, no
problems with solderability.
