I have been using the Heraus paste for almost ten years. At the time we picked it, it and Loctite seemed like the only options. It was a lot less $$ than Loctite. Is there a noticable difference in performance? I think the Loctite was about 2X the pr

since 1999 we use Heraeus PD944, in time we tested Loctite also but had some issues with it - or with our machine specialist :)) we dispense with Fuji CP (2 , 3 & 4) it only creates problems when its on the solder pads ;-) best wishes

Maybe much more detailed than you have available but do you know the exact prepreg number you were using in the failed units? That is one of the only similarities I have been able to isolate on my parts - I am curious if it may be the same. Thanks,

I'm not sure what it was. It would be tough information to get as it's an old issue and sore spot with our supplier. I'm not even sure if we use them anymore for these boards.
