  Optimize your board layout for efficient assembly by considering component orientation, spacing, and alignment. This reduces assembly errors, minimizes costs, and speeds up turnaround time. Adhering to these guidelines makes automated processes more accurate and cost-effective.
• Gerber Files
  Submit clear and accurate Gerber files, including all necessary layers (copper, solder mask, silkscreen) and drill data. Ensure all files are correctly named and in the required format to prevent delays and errors in the manufacturing process.
• Bill of Materials (BOM)
  Provide a comprehensive BOM with accurate part numbers, manufacturer names, and quantities. Using specific part numbers and manufacturer information allows the assembly service to source the exact components, avoiding compatibility or performance issues. Proper documentation is crucial for an efficient assembly process.
• Component Footprints
  Ensure accurate component footprints in your design to avoid assembly issues. Double-check all component footprints match the manufacturer specifications before submitting for assembly. Incorrect footprints lead to misalignment, poor solder joints, and potential functional failures.
• Panelization
  When ordering multiple boards, consider panelization for efficient assembly. Panelization arranges multiple copies of the PCB on one manufacturing panel, streamlining the production process and lowering costs. Verify the panelization process is in accordance to the manufacturer’s guidelines.

Choosing the right online PCB assembly service involves understanding the specific needs of your project, along with the capabilities of various platforms. Consider factors such as assembly complexity, production volume, and required testing, when making your selection.
