I have a customer that is requesting their flex circuit be conformally coated. Is this something that is done? Which coating would stand up to the stresses of flexing? Wouldn't that put stress on the components? Thanks! Shannon

At a previous job I had been taught that when reflow soldering polyimide flex circuits, it was necessary to pre-bake them before reflow soldering to prevent delamination. Our procedures said that there must be a 1hr bake prior to reflow, and the flex
