What documents are needed for custom circuit board manufacturing?:
1. Gerber Files (Design Data)
• Gerber (.gbr) or ODB++ files.
• These are the standard industry files that contain all the layer information (copper, solder mask, silkscreen).
• Note: Please ensure the files are in RS-274X format.
2. Drill Files
• Excellon Drill File (.drl).
• This file specifies the location and size of all the holes (vias and component holes) on the board.
3. Bill of Materials (BOM)
• A list of all the components required for assembly.
• Include Part Numbers, Manufacturer Names, and the Quantity for each part.
4. Assembly Drawing
• A top/bottom view drawing showing the exact position of each component.
• This helps in verifying the placement and orientation of parts.
5. Technical Specifications (Specs)
• Layer Count: (e.g., 4 Layer, 6 Layer).
• Material: (e.g., FR-4, Rogers, ABF for IC Substrates).
• Copper Thickness: (e.g., 1oz, 2oz).
• Surface Finish: (e.g., HASL, ENIG, Immersion Gold).
• Board Dimensions: Length and width.
6. Additional Requirements
• Impedance Control: If specific impedance values are needed (e.g., 50 Ohms).
• Silkscreen: Any specific text or logos to be printed on the board.
• Packaging: Any special packaging instructions (e.g., vacuum packing).
