Greetings, I have been away from the industry for about six years and returned to find myself in the black arts, the land of mystery and intrigue. Iım work in a Flex Manufacturing facility. I was hoping to pry some wisdom from this talented group about the lamination process as it involves flex and rigid flex products with respect to vacuum vs. conventional lamination presses. Items of interest or maybe I should say confusion are; 1. Benefits of vacuum ? 2. Low pressure vs. High pressure lamination in a Vacuum press. 3. Cold start up vs. Hot start up 4. Any methods to control registration in sequential, redundant, as well as general lamination 5. General dangers I realize that is asking a lot, but it doesnıt hurt to try. Is there any good information in print or electronic form that my provide me a path to follow. I am also looking for insights Plasma desmear and etchback... But I ll just try this for now. Everyone have greet Fatherıs Day, if the shoe fits as my father might have said.
