Fellow Technetters,

        I am looking for a water soluble solder mask that can be compatible
with stencil applications. We do quite a lot of solder mask applications
with a dispensing machine, but I am really looking into using a stencil
since it would speed up the process and help the ability to apply thinner SM
layers. I tried to do it with the one we use on the dispensing machines, but
it's too liquid and starts to cure at ambient temperature after 30 minutes,
so it was not possible.

        Ha anybody accomplished this? Would there be a special WS solder
mask for stencil applications?


        Any comments would be appreciated
