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

Hi, has anyone experienced discoloration of cured non-conductive epoxy? It turned from white to deep red. The parts were returned from customer and we noticed the color change and wondered what could cause epoxy discoloration.Thank you!

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

Not sure exactly what kind of coverage your looking to get but we use Dow Corning 3-1944, it's room-temp cure and rather thick, (think warm honey). But we have found it useful on several projects. http://www.dowcorning.com/applications/search/produc

We agree with "guest" above. This a "chip bonder" type material used to improve the reliability of array type devices. "A relative comparison of the N50 values is given below: No underfill = 1.0X (baseline) Corner bond = 1.3X Non reworkable underfi

Humiseal probably won't work as most of them are solvent based or require pretty high temp cures. MicroCoat technologies manufacturers UV cure epoxy conformal coating materials that have been used to coat just about anythin (except the green fog) Cal

Try "Amicon D125 F". Good for both dispensing and screen printing. I like the yellow colour, it shows up better on green pcbs. Most smd adhesives are single part, heat cured epoxies, UV curing having gone out of fashion some years ago. Amicon used to
