I have a need to dispense a latex masking material using an automated dispensing system. We are presently looking at the I&J750. Does anyone have any experience with this piece of equipment, or have a better solution available?

Currently use Hysol TS300 latex mask and need to explore alternative methods of drying the mask. The mask is applied with a Asymtek Century Dispenser and placed on drying shelves. Air dry is dependent on temperature/humidity. Tried all the UV masks o

Eric: I�ll pass on the uV and ammonia, also. Thoughts are: 1 You�re correct that the temperature/humidity mix can be a big driver to latex peelable solder mask cure time, but don�t overlook material thickness. Dispensers put material in a very th

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

The only thing ammonia can do is tarnish copper and make it more difficult to solder. And the higher temp in lead-free will discolor the latex (giving it a sticky surface), but the functionality of the mask will be intact. There should be greater co
