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

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

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
