PCB PI Stiffener (Polyimide Stiffener) for FPC Profduction

PI Stiffeners is also called Polyimide Stiffeners. The products are mainly divided into glued Stiffener and non-adhesive Stiffener. It is widely used in electronic products, mainly to solve the problem of poor load-bearing capacity of flexible circuit boards, and to improve the strength of the load-bearing part to enable the overall assembly of the product.

PCB PI Stiffener (Polyimide Stiffener) for FPC Profduction

As a special engineering material, PI has been widely used in aviation, aerospace, microelectronics, nano, liquid crystal, separation membrane, laser and other fields. It has flame retardancy, high temperature resistance and low temperature resistance at the same time, and the long-term use temperature can be -200 ℃ ~ 426 ℃. In the production of FPC, the PI used is mainly PI protective film and PI Stiffener. The PI protective film is used as circuit insulation, and the PI Stiffener is used in the area on the back of the FPC gold finger. The thickness of the PI Stiffener is mainly based on the design drawings and the use environment, and PI Stiffener of different thicknesses are selected for pressing.

Features

-Excellent heat resistance
-Excellent flatness
-Excellent chemical resistance
-Excellent mechanical and electrical properties
