Files Requirement

  1. Gerber or ODB++ Files

    Please include all the layers (copper, solder mask, silkscreen, solder paste, outline, thru-via hole, blind and buried via, micro-via, carbon ink printing, FPC stiffener, EMI film and etc.).

  2. Bill of Materials (BOM)

    Preferred in .xls or .xlsx format. Your BOM should include:

    - Reference Designators

    - Quantity of each part

    - Manufacturer Part Number (P/N)

    - Manufacturer

    - Part Description

    - Type (SMD, Thru-Hole, Fine-Pitch, BGA, etc.). (optional)

    - Package (QFN32, SOIC, SOT23-5, 0402, 0805, etc. package is very helpful and optional, but not required).

    While, it is highly desirable to include columns to indicate whether the parts are consigned by you, MADPCB supplied or not fitted. Download our free Bill of Materials (BOM) template for excel for reference.

  3. Centroid File

    Also known as pick and place file, or coordinates file. It should include component locations, rotations and reference designators in .csv format.

  4. Assembly Drawings (Optional)

    Supplementary, but useful for complex PCB and assembly manufacturing requirements. Usually in .pdf format.

During the PCB and assembly process, MADPCB may find some questions, and need to communicate the turnkey PCB assembly and shipping with you.

BOM Questions: Parts procurement of MADPCB might have questions in the first 1-2 days after a turnkey PCB assembly order is placed, normally solved over email.

DFM Questions: Our engineering team performs a review of your design in the first 1-2 days after the PCB fabrication order is placed, often send over email as an excel file with figures to explain engineering questions (EQs) and suggestions.

PCBA Photos & Shipping: When PCB assembly finished, the PCBA photos will be sent out via email immediately, and the shipment is held pending your review and approval of the photos.

With advanced assembly equipment and skilled technicians, now our assembly lines are versatile for Rigid PCB Assembly, Flex PCB Assembly and Rigid-flex PCB Assembly with FR4, Rogers, Metal Core, Ceramic, Polyimide (PI) and Polyester (PET) substrates. Daily SMT capacity reaches 1.5 million points.
