There is no difference between a circuit board and a circuit board, and they are essentially the same. The circuit board is just a designed and manufactured substrate, and the circuit board refers to the circuit board on which various components have been
PCB has a long process, and there is a lot of room to control the production cost. The production cost includes: raw material control; water and electricity control; scrap rate control; process control, etc. 1. Raw material controlThe same board, who can
The circuit board (PCB) is arranged according to the electrical schematic diagram (SCH), and the text symbols representing the elements should be consistent with the schematic diagram. The text symbol can be checked GB7159. For example: L—reactor or induc
Circuit boards are divided into single-sided circuit boards, double-sided circuit boards and multilayer circuit boards. Multi-layer circuit boards refer to circuit boards with three or more layers. The manufacturing process of multi-layer circuit boards will add the manufacturing process of inner lamination on the basi……
PCB operation process, the following is the general production process: 1. Inner substrate (THIN CORE) 2. Inner layer circuit production (laminating) (Dry Film Resist Coat) 3. Inner circuit production (exposure) (Expose) 4. Inner circuit production (Devel
1. PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board. It is an important electronic component, a suppo……
