Your point about thermosets getting soft in the preheater of the wave is well taken. But an adhesive that is used past its expiry or other up-front lack of process control represent 99 & 44/100 percent of the reason for �glued parts falling off in

Wudduya mean ya can�t replace that ol� John Trieber? We agree. * Waverider thingies are best used to set-up process and in machine start-up. * Monitoring product characteristics is expensive, gives little information, and is so sloooow. [Plus we tu

I'd tend to agree with what the others have said. Check the basics, board supports, setup, wiper paper working correctly. If it's a humidity issue, try taking some paste, place it on a chem wipe, and roll it around a bit, which removes some of the mo

Dave, you are ahead of me again. I was thinking that this morning. however it clearly is a problem for him and I based the rest on my experience, anything can be improved but at what cost. If nothing else he can get more boards off his line at the

Thanks for all the responses! I definitely agree, I don't like the idea of using floppies, either - and our HD is WELL, and regularly, backed up. While I both program and operate the machine, mgmt is insistent on this method. I ended up just copyi
