seen it many times before when the resist is not cured at manufacturing. get PCB man to check with K type thermal couple that boards ARE in fact cured. this is normally 155C ON board temperture not oven setting Cheers Greg

Hello, another SME is saying the solder resist cure level is suspect. I have had a industry SME make reference to this too. Adjusting the cure of the resist changes the surface energy

What is the humidity level in your facility? We maintain ~40% year round and never have any issues regarding ESD from cover tape peeling.

Anybody who could help me what is the tape peel off speed of PANASONIC CM602 for 8mm feeder? Appreciate your feedback.

Hey, great, thanks! Now I can check with my machine maker and see what their feeders are spec'd to. I may send a reel of parts out to be tested, too.

Hi to everyone in this forum. I came across this problem recently. Im not sure how it started and its rootcause. The chip resistor termination has been peeled off. Thanks in advance for all your advise.

We only reapplied in areas where significant wear was observed. As I mentioned, shop chairs moving back and forth, combined with lead trimmings and other debris led to scraping and peeling over time. Other than that, no, we did not re-apply over

have done it in the past, used silicon as it will flex,, however its not the most robust material! tends to peel/flake off.
