Anti-tack measures for masks during exposure! Film products that are easy to peel off after exposure.
The "Solder Resist Protective Film" is a film product primarily used in the manufacturing of printed circuit boards. When forming the solder resist (SR) on the outermost layer of a printed circuit board, especially when using liquid resist to create the SR layer, measures are taken to prevent mask tack during exposure and other FM countermeasures. This product has good adhesion to SR printed or coated with screen printing or roll coating, and it is easy to peel off after exposure, which is why it is currently used by many customers. 【Features】 ■ Primarily used in the manufacturing of printed circuit boards ■ Implements FM countermeasures such as preventing mask tack during exposure ■ Good adhesion to SR printed or coated with screen printing or roll coating ■ Easy to peel off after exposure ■ Custom specifications available *For more details, please refer to the PDF document or feel free to contact us.
