Hello all, Thanks to all, by the way, for help on my last delamination problem on flex circuits - we think we've licked it. Here's my next question: I'm wondering about the degradation of performance of acrylic adhesives with exposure to temperature. I think I've seen a lot of people mention that the adhesive becomes brittle over time at exposure to heat. Does anyone have any data they can share? Also, are there other properties that are affected? Does the bond strength suffer? Thanks for any info! Matt Sanders Matthew Sanders PCB/Metal Procurement Engineer, Trimble Navigation Ltd.
