PI reinforcing board plays an important role in the quality of FPC

In the production of FPC(flexible circuit board), it is necessary to strengthen the local or the whole processing, that is, to increase the local thickness or hardness, so as to solve the problem of the flexibility of the flexible circuit board, improve the strength of the plug part, convenient product integration Bulk assembly.

As an excellent supplier of FPC materials and a subsidiary of Zhengye Technology Co., LTD., Nanchang Zhengye independently researched and produced PI reinforcing board, which selects PI film, known as "gold film", as the main raw material. It has special properties such as high temperature resistance, high toughness, corrosion resistance, etc., which is widely applicable to the reinforcing needs of FPC.

Improved bearing capacity for integrated assembly

PI reinforcing board is also called reinforcing board, reinforcing board, mainly divided into adhesive reinforcing board and non-adhesive reinforcing board.

Performance advantage

Excellent heat resistance

Long-term use temperature -269-400°C, high temperature part：no obvious melting point, after improvement can reach a higher level; Low temperature：Liquid ammonia at -269°C does not crack.

Insulation and dielectric properties

Dielectric constant is usually about 3.4, through the improvement, can be reduced to about 2.5, dielectric strength of 100-300kv/mm, in a wide range of temperature and frequency range can still maintain stable performance.

Excellent chemical resistance

Some varieties are insoluble in organic solvents, stable to dilute acid, generally not resistant to hydrolysis recovery of up to 80%-90%.

Safety and environmental protection

No halogen, no antimony, UL94V-0 flame retardant grade, low smoke rate, flame retardant performance; Non-toxic, it can be used to make tableware and medical utensils and can withstand thousands of sterilizations.
