Scapa 557 is a low-static pressure-sensitive silicone adhesive film designed to mask and protect gold finger contacts on PCBs during high-temperature wave soldering and hot air leveling processes. This polyimide film can eliminate PCB degradation because of electrostatic discharge. The product is thin and conformable, and can mask uneven surfaces. According to the company, it can withstand operating temperatures up to 500°F, and removes cleanly, even after prolonged exposure to heat and chemicals. The product provides puncture, tear and abrasion resistance, and is impervious to chemicals. It performs well in both horizontal and vertical hot air leveling machines.
