From the Customer’s Perspective: How to Prepare a Complete PCBA Order Package

Why Complete PcbA Documentation Matters

A complete and accurate PCBA documentation package is the foundation of successful electronics manufacturing. It enables fast quoting, precise assembly, and smooth testing. Missing or incorrect files can lead to delays, added costs, or manufacturing defects.

Whether for prototypes or large-scale production, complete files help your supplier deliver high-quality results—faster.

Essential PCBA Order Files: The Complete Checklist

1. Gerber Files (RS-274X Format)

• Include copper layers, Solder Mask, silkscreen, and drill files
• Ensure file names are clear and layers are correctly aligned
• Export from tools like Altium, Eagle, or KiCAD
•  

2. Bill of Materials (BOM)

• ·Format: Excel or CSV
• ·Include fields like:
  • ·Designator (e.g., R1, C3)
  • ·Quantity
  • ·Description & Value (e.g., resistor, 10kΩ)
  • ·Package/Footprint (e.g., 0603, QFN-32)
  • ·Manufacturer Part Number (MPN)
  • ·Preferred Vendor or Alternatives

3. Pick and Place File (Centroid)

• ·Required for automated assembly
• ·Include reference designator, X/Y coordinates, rotation, and top/bottom layer info

4. Assembly Drawing (PDF)

• ·Shows component placement and orientation visually
• ·Useful for manual soldering or verifying placement

5. Testing Instructions

• ·Include test procedures: FCT (Functional), ICT (In-Circuit)
• ·Provide test criteria and equipment/jigs if needed

6. 3D Model / Mechanical Drawing

• ·Optional but helpful for housing design and connector alignment
• ·Formats: STEP, IGES, or PDF

7. Special Requirements

• ·Examples: conformal coating, masked vias, gold fingers
• ·Specify IPC class, material standards, or packaging instructions

Typical Workflow: From Files to Final Product

[ You → Engineering Review → Quotation → Sample Build → Mass Production ]

💡 Tip: The more complete your documentation, the faster production starts.
