I had a similar problem. We wold begin to notice the debonding within hours after recieving the stencils. As it turned out, our stencil vendor, located in CA, was shipping the stencil to our facility, located in ND, before the epoxy was fully cured

You're right, manufacturers time/temps will vary. A single manufacturer will have a host of materials with different cure schedules. We currently use 2 epoxies that cure in 2 - 3 minutes at 150�C. One will also cure in 5 minutes at 125�C. Talk t

There are two primary causes of epoxy adhesive bond failure, heat and over exposure to moisture. Ultrasonic cavitation is a only a mechanical "scrubbing" action on a microscopic level. However, if the adhesive bond is week or has small areas of det

Could anyone please give me some insight on the time/temperature requirements for curing SMT adhesive used for a high temperature (96/4 solder) application in a bake oven, rather than using reflow? I understand that it would probably vary from epoxy

I appreciate both of your responses. I spoke with a tech rep at a distributor of the Loctite 3609 and asked him if this adhesive can be cured using a bake oven (Blue M, Despatch, etc.), rather than convection/IR. He stated that he's never heard of

I'd be leery curing the E-30cl Material at temps above 90 degrees C. (I believe the flashpoint is 93 Degrees C)
