The main files involved in PCB copying board include chip program file, PCB file, bill of materials (BOM), schematic file, Gerber file, drilling file and center coordinate file. These files play a vital role in the PCB copying process, ensuring the accuracy and functionality of the copied board.
1. Chip program refers to the set of instructions stored in the chip that control the behavior and function of the chip. Chip programs usually exist in the form of binary code, which is executed by hardened circuits to achieve a specific function. If there is no MCU control board can ignore this.
Generally speaking, the program is our brain thinking to guide our actions, and the PCB and components are our bodies.
2. The PCB file is the basis of the circuit board design and contains a detailed description of the physical structure and electrical connections of the circuit board. Through the PCB file, you can accurately restore the board and analyze the layout and wiring .
3. The bill of Materials (BOM) lists all components required for the circuit board in detail, including device model, package, parameters, description and quantity, and the position of the PCB board, etc., to ensure the correct procurement and placement of the components.
4. The schematic file shows the various functional modules of the circuit and the electrical connection between them. It is the basis for understanding the working principle of the circuit and is helpful for maintenance, analysis and secondary development .
5. The Gerber file contains the geometric information of each layer of the circuit board, such as copper line, pad, solder mask layer and screen printing layer, etc., is one of the key files for the manufacture of PCB board .
6. The drilling file provides the coordinates and dimensions of the drilling to ensure the correct drilling of the PCB board and the accurate installation of the components .
7. The center coordinate file , also known as the pick and drop file, provides coordinate and orientation information for each component on the board, guiding the precise placement of the components .
These documents together constitute the complete technical data of the PCB copying board, through which the design, manufacturing and testing of the circuit board can be carried out, and the replication, secondary development, analysis and production of electronic products can be realized.
