Hello everyone, Has anyone had success dispensing ammoniated latex masking using a valve? If so, what company and type of valve are you using? Our current supplier of non-ammoniated latex masking will no longer provide a container larger than an 8 o

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

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.

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

Latex gloves will cause this kind of reaction.

You might want to try 100% nitrile gloves. They are ESD safe and will not irritate the skin like latex.

Have you considered replacing the insulative latex with disipative rubber matting?

Bill, Likely the latex isn't conductive, so charges will not be dissipated to the metal rack. Whether that constitutes an ESD risk or not will depend on the generative properties of the latex. I've never tested units inside my wash, so I can't spe
