Alan,
Yes, I said up front I've never been around PC board production but I'll have to thank you anyhow for your condescending replies, I'm sure it was the absolute best you could offer.
It never ceases to amaze me that asking a serious, simple, polite question can result in such a smart ass attempt at a reply.
Are you too intelligent for the rest of us, or too impatient to pointedly answer a question? Oops, I really don't want an answer.
Anyhow, a whole hour on the History Channel, who boy I am sorry I wasted all that time and money on Engineering and Polymeric Tech. courses.
Just study notes alone concerning rubber, I've got a 4 inch thick notebook on natural elastomers and another on synthetic elastomers up in the attic plus a couple decades of work experience. If your "5 second search on Google", label reading or watching "Oprah" doesn't give you all the education you need you may want to try Dr. Phil.
Thanks again,
Denny
