At present, the coating method of resist is divided into the following three methods according to the precision and output of circuit graphics: screen missing printing method, dry film / photosensitive method and liquid resist photosensitive method.

FPC soft board is an important electronic component. It is also the carrier of electronic components and the electrical connection of electronic components. Through the analysis of the development of FPC soft board in the main regions, the market development trend and the comparative analysis of dom......

of FPC is becoming more and more significant in order to achieve more functions. Now Jin Baize will talk about the characteristics of FPC on the advantages and disadvantages of FPC.

Before designing multi-layer PCB circuit board, the designer needs to first determine the circuit board structure according to the scale of the circuit, the size of the circuit board and the requirements of electromagnetic compatibility (EMC),

PCB (printed circuit board), whose Chinese name is printed circuit board, is one of the important components in the electronic industry. Almost every kind of electronic equipment, from electronic watches and calculators to computers,

FPC circuit board can be divided into single panel, double-sided board and multilayer board according to the number of circuit layers. The common multilayer board is generally 4-layer board or 6-layer board, and the complex multilayer board can reach dozens of layers.
