PCB finished products are divided into soft and hard. Below, Zhongke Circuit will introduce the difference between PCBs with different hardness.
1. PCB hard board
Rigid board is a board made of PVC as raw material. PVC rigid board is a widely used product in the industry, especially in the chemical anti-corrosion industry.
PVC is a resin resistant to acid, alkali and salt. Because of its good chemical properties and relatively low price, it is widely used in chemical, building materials, light industry, machinery and other industries.
2. FPC soft board
The soft PVC extruded sheet is prepared by adding plasticizers, stabilizers, etc. to the polyvinyl chloride resin by extrusion molding.
It is mainly used for the lining of anti-corrosion equipment such as acid and alkali resistance. It can also be used as general electrical insulation and sealing gasket material. The operating temperature is -5 to +40 °C. It can be used as a substitute for rubber sheets. product.
3. Rigid and soft board
The birth and development of FPC and PCB gave birth to the new product of flexible and rigid board. Therefore, the flexible and rigid board is a flexible circuit board and a rigid circuit board, which are combined according to the relevant process requirements after pressing and other processes to form a circuit board with FPC characteristics and PCB characteristics.
Shenzhen Zhongke Circuit Technology Co., Ltd. is a high-precision PCB multi-layer circuit board manufacturer, focusing on PCB circuit boards, HDI circuit boards, rigid-flex boards, high-frequency boards/high-frequency circuit boards, and PCB blind and buried via boards. , Long strips, super long circuit boards, strip circuit boards, double-sided super long boards, super long circuit boards, special circuit boards, etc.
