Flexible circuit board For liquid crystal display

1. Industrial positioning     

There are many ways to classify PCB. According to the # color lcd display screen # flexibility of the base material, it can be divided into rigid board (R-PCB), flexible board (FPC), and rigid-flex board; Panels, multi-layer boards. In addition, there are special product categories, such as high-speed high-frequency boards, high-density connection boards (HDI), packaging substrates, etc.

2. Production process

The production process of PC can be roughly divided into two parts, one is the production of the circuit layer, and the other is to combine. To press and reprocess the circuit layer with other layer materials, and finallymade a complete FPC. When the signal transmission line is distributed on the outermost layer of the FPC, in order to avoid # 5.5 inch touch screen display # signal distortion caused by electromagnetic interference during the signal transmission process. The FPC will press a layer of electromagnetic shielding film after pressing the cover film to shield the external electromagnetic interference. So as to ensure that the FPC circuit can work normally.

3. Classification

According to the number and structure of the conductor, FPC products can be divided into four categories: single-layer, double-layer, multi-layer FPC and rigid-flexible circuit boards. With the increase of the number of layers, the number of lines and signal # tft lcd modules # transmission capacity that can be accommodated in the same volumeboth have increased significantly. The volume occupied by the FPC board has been effectively reduced, which provides convenience for the terminal product to accommodate more functions.
