PE protective film for PCB circuit board dry film

Product Description

PE protective film for PCB circuit board dry film

PCB circuit board dry film is divided into three layers:
PE protective film
Middle dry film layer
PET protective layer

Among them, the PE protective film layer and the PET protective layer are used to protect the dry film layer. They will be removed before lamination and development, so that the middle dry film layer can better maintain its own viscosity and good photosensitivity.

The PE protective film produced by Chaowei Plastic Film Co., Ltd. has few crystal points, is easy to tear, easy to stick, does not leave marks, has a smooth and clean surface, no particles, bubbles, pinholes, foreign impurities, excellent mechanical properties, uniform thickness tolerance, low heat shrinkage, and good separation effect. It can better isolate oxygen and maintain and prevent product scratches. Therefore, the dry film surface used for PCB circuit boards can better protect the dry film and prevent the dry film from being damaged in various links such as production and transportation. Isolating oxygen can prevent the dry film from oxidizing, reduce the impact of the external environment on the dry film as much as possible, improve the photolithography effect, and ensure the accuracy and quality of circuit board production. In addition, the Chaowei PE protective film can also prevent the dry film from contacting other materials or objects to avoid accidental interlayer adhesion or contamination.

Super PE protective film can be used for PCB circuit board dry film protection, PCB electroplating process protection, PCB gold plating process protection, optical grade lens protection
