There's some nice low-VOC uV coatings out there. We don�t use uV cured coatings, but try: * http://www.emersoncuming.com * http://www.dymax.com * http://www.mgchemicals.com * http://www.loctite.com * http://www.humiseal.com Be aware that uV co

We use one quite often. Our machine is a Uvitron Conveyor 40 as we are a large coating house and this allows us to process many boards. Dymax also maufactures and sells machines as well. Humiseal and Dymax both manufacture UV coatings. Emerson Cuming

Gary: It doesn't matter what you use to cure your glue. SMA adhesives are thermosets. This means they become hard on cure and this is not reversible. A couple of things go on with SMA adhesives when you heat them. * Their rheology is temperature

What can cause solder balls to appear after conformal coating? Using Dymax 9-20557, light curing for 1.5 mins. Can too much heat from light cure cause solder balls?

Well Dave, Check the number that is on your adhesive tube. They make several different types of adhesives for use on different substrates. The rep from Dymax recommended the 3073 for bonding to FR4. We use a Dymax HHL400 handheld curing light. Click

UV40 for you info was developed in Humiseal EU and has been tested heavily against Dymax product. UV40 is a great product has many approvals from major auto and whitegoods makers.... I have seen comparisons UV40 to Dymax 984LV and Dymax comes out se

A few other data points to consider. My experience working with Dymax 984LVF material was that its UV cure must be initiated immediately after coating, otherwise is surface will remain tacky forever, something like a post-it note tackiness, which wi
