Just wondering if anyone else has had problems with Kester made from Mexico. We are seeing alot of bridging lately in our product and it started about a month ago.

It could be one of a dozen things besides your paste. If you do feel it's your paste, have another vendor come in awith a free sample to try it. Side by side comparisons are great and it wouldn't cost you anything.

James, Kester must have the same quality standard worldwide. If you feel your problem is related to the paste itself, you should write a report and submit it to Kester directly.

Do you have new operators at the area any any chance?

Thanks, Hiram

We have Kester 256 no-clean spec'd as an alternate paste. I bring some 256 in occasionally to make sure it still works as a backup. The last batch I brought in was bridging like crazy. Scraped it off the stencil, put our regular Alpha back down and the bridges went away. Haven't had this problem before. Kester suggested stencil aps, screen printer parameters, oven profiles and everything but their paste. Didn't check where the batch was mfg'd. Be curious to here if you find out anything.
