Best answer

PCB circuit board assembly requires the following documents:

1. Gerber file: Gerber file is a commonly used file format in PCB manufacturing. It contains geometric information of each layer of PCB, such as copper lines, pads, solder mask layers and silk screen layers.

2. Drilling file: The drilling file provides the drilling coordinates and size information of the PCB, and specifies the aperture sizes of components, via holes and mounting holes.

3. BOM file: The BOM order is a detailed list of all components on the PCB board, including part number, component value, description, quantity and other information.

4. Center coordinate file: The center coordinate file is also called a pick and place file. It provides the coordinate and direction information of each component on the PCB board and guides the position of the component on the PCB board.

5. Manufacturing drawings: Manufacturing drawings are engineering drawings. In order to provide PCB board manufacturers with reference during the production process, they contain key information such as PCB board size, drilling size, layer stacking, tolerances, surface treatment and other manufacturing-related details. .

6. Assembly drawings: Assembly drawings are additional information provided during the PCB board process and include all special instructions, such as component placement details, reference numbers, directions, and assembly technicians, etc.

Please note that different PCB manufacturers or PCBA projects may have different requirements and documentation requirements. If necessary, it is recommended to consult relevant personnel to obtain specific and timely information.
