 We are using and have been using a UV curable - peelable solder mask for 
about 3 years now with very good results
the maskant we are using is Dymax 945 with a conveyorized UV light source. 
Our typical cure time is 15-20 sec.
The only negative to this product is that it does leave a slight stain on 
fr4 with or without soldermask.

I am looking for information on peelable soldermask used prior to wave 
soldering.  We currently use Alpha 110 and must allow 3-4 hours drying time 
on thicker areas.

1) What peelable mask do you use and how much time must you allow for it to 
dry before you can run it through the wave?

2) Does anyone have experience with UV curable mask?
