During solder reflow indiscriminate delamina- tion of thin FR4 to aluminum rigidizers (utilizing Pressure Sensitive Adhesive (PSA)) is an unaccept- able problem that requires stringent quality control with no valued added content. The current contain- ment is to bake all the laminations prior to use in a static oven at 120°C for three hours followed by a one hour cooling period with the oven door open.
