1. BOM list for PCBA processing

The BOM list, also known as the material list, is a standard document and production program file used to inspect the quality of PCBA processing with incoming materials. It records all electronic materials that need to be used in PCBA processing, including brand, model, description, usage, and other information. The electronic materials used on the entire PCBA board will be reflected in the BOM list, so the existence of the BOM list is the most important part in PCBA processing.

2. PCB files and Gerber files

Gerber files are files exported from PCB files, which include circuit board layers, solder mask layers, steel mesh layers, solder pad layers, silk screen layers, etc. In the actual PCBA processing and production process, Gerber data is not only used to make steel mesh, but also to make SMT programs. Usually, when quoting PCB board making and PCBA SMT processing, Gerber data is also needed to refer to for quotation.

3. Coordinate file

Coordinate files are a standard for locating the coordinates of PCBA mounting components in processing equipment programs. In the automation equipment used in PCBA processing, the coordinates of positioning points are almost always used. It is mainly used to locate the coordinates of components. When engineering programs, this file is needed (such as SMT machines, SPI, first article detectors, AOI, etc.), and the coordinate file can also be exported from PCB files.

4. Sample provision

The sample is generally provided as a reference for PCBA processing plants, such as the polarity direction of components, the amount of solder applied to solder joints, coding, marking, and other process references.

5. Process guidance documents

As the customer's control over the key quality of the PCBA processing plan in the product, they usually provide guidance documents for the PCBA processing plant. Contains special requirements and design points.

6. Test files

After completing all the processes of PCBA processing, customers generally have requirements for various testing items, including testing project parameters and technical indicators. Testing guidance documents are generally provided by customers, which include guidance and technical requirements for professional testing parameters requested by customers.
