This material contains acetone in 30% plus range and toluene with this solvent combination ink is not an option. You will have to get a CC that doesn’t contain acetone as solvent.

Having success with Circuit Boards #432 Solvent Resistant Ink - Designed specifically for circuit boards. This medium dry ink is highly resistant to solvents .... It is also non-conducting. Note: this ink contains an aggressive solvent so should not

Since the bubbles: * Are only on the solder connection, we'd guess there must be some compatibility issue between the flux residues and the conformal coat materials. * Occur after curing, we'd guess the cure recipe is too rapid and is entrapping voli

The coating thickness is more a property of the individual coating itself. The 0.03 - 0.13 is based on average properties of acrylics in general. It's like trying to pour 3 mils of motor oil on a table. The material will find it's own thickness.

Tom: Once again - why are you using solvent based conformal coating. 1B31 is OK as a CC but it contains Toluene and MEK!! It is only 35% solids which means you are trying to get rid of 65% solvent. If you must use it due to customers requirement then

We're unaware of any such reaction. The RoHS Directive bans the use of six hazardous materials. The materials are four metals: lead, cadmium, hexavalent chromium, and mercury; and two brominated flame retardants: polybrominated biphenyls (PBB) and p

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

Hi sforman1 Are you refering that the UV is able to cure on solvent based material too ?

have done it in the past, used silicon as it will flex,, however its not the most robust material! tends to peel/flake off.
