Essential Files for PCB Manufacturing
- Gerber File: The Gerber file, derived from the PCB design, includes crucial layers like the Pad layer, solder mask layer, silk screen layer, and stencil layer. While essential for manufacturing, companies may opt to disclose only necessary data to prevent plagiarism.
- BOM (Bill of Materials): The BOM offers a detailed list of materials needed for production, directly corresponding to components in the final product. It is a vital reference for material procurement and the manufacturing process.
- Coordinate File: This file, used to create pick and place files, provides precise device location data. It should be in .txt or Excel format and must include the PCB origin, usually located in the lower-left corner.
- Location Map: The Bit Number Map visually displays the arrangement of pads and silk screen layers, assisting in verifying the accurate positioning of SMT materials during assembly.
