The article I was referring to is called "Process Advantages of Edge
Conveying with Product Support during Reflow" and it appeared in the
September 1990 issue of SMT magazine. It talks about the causes of PCB
warpage and Product Support conveyors as a solution to that problem. Article
is pretty old but still offers insight to this problem.

I would be happy to provide a copy to anyone who would like one. Just e-mail
me with your fax number. I don't mind sending this out 100 times if
neccessary (receptionist may but that's another story) but please be patient
as I am getting quite a few requests.

Sincerely,

Brian
