Sorry folks. I really screwed up with my loose comment concerning delamination being assured. I should have, and meant to say, without effective process management (right equipment, tools, processes, parameters, materials, training, etc.) delamination will be assured. I also should have said a major adhesive material is acrylic. Again, my apologies and thanks for jumping on it all.
