There are many liquid masking manufacturers. Some even use acrylic vice latex. Try Contronic Devices. They make their mask in multiple viscosities depending on how you will apply it and where.

tombstonesmt: Ammonia based masks can create solderability issues after they are removed. You can get non-ammonia based latex mask material but down side is slower cure and cost a little more as they have higher levels of latex etc

Sarason, This idea has been brought to the table... The issue with the ammoniated latex is that any friction causes shear curing inside the valve. We did find a Techcon "Pinch Valve" that we will be running some samples through. It has a dispos

If you are not washing and want to stay with a peelable mask the two basic types are vinyl and latex. Although we've seen some silicone and urethanes, they cost more. * Do not use latex peelable solder mask with a low residue soldeing process withou

We use Humiseal T300 latex mask for over 17 years. No smell. That said we have been dispensing several ways. One is a Asymtek 718 in-line machine using a 1 gallon pressure pot and their DV7000 valve. It is an auger valve that has been highly successf

Try a liquid latex masking material. Youll most likely have to cover the hole with kapton, really drench the thing in the liquid latex to prevent the ultrasonic from damaging it then bake it at 50-70c for about 2-4 hours. With no bake its usually a 2

Is there a peelable solder mask which can withstand an automated aqueous wash ? I need to prevent water ingress into SMT modules during the wash cycle.

I would suggest trying an acrylic peelable mask. In most cases peelable temporary masks are latex materials. Since you use an acrylic conformal coating it makes sense to use a mask with the same make up to avoid incompatabilities. Link to acrylic mas
