Hi All, I am retrofitting a machine with a solder paste dispenser head, and am trying to decide what direction to go, with a dispense valve. The choices I know are either a standard Air over, or some kind of positive displacement valve such as a sc

Chad, We currently use the PD pump technology, and do not have any problems. I would be glad to discuss some of our process variables with you. Drop me an email with your phone number and I will give you a call. MIKE

So far I know of two dispensing system cleaner and conditioner to purge the solder paste out to preserve the valve. Valve Purge from EFD Nordson and Purgel from Interflux. Are there any other alternatives for purging and cleaning dispensing systems?

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
