This section provides guidance on key aspects to consider when designing PCBs for online manufacturing.

• Gerber File Accuracy
  Ensure your Gerber files are accurate and correspond precisely to your design. Use the correct export settings from your design software, verify the files using a Gerber viewer before submitting and double-check each layer. A misplaced trace or via can cause a board to fail. Most online manufacturers have their own free Gerber viewers.
• Clear Drill Files
  Verify your drill files are in the correct format (typically Excellon) and that the hole sizes are clearly specified. Overlapping holes, incorrect units, or missing hole sizes cause processing delays and potential board defects.
• Minimum Trace Width and Spacing
  Adhere to the manufacturer's minimum trace width and spacing specifications. Insufficient width or spacing can lead to opens, shorts, and reduced signal integrity. Online manufacturers often have limitations based on their equipment capabilities. For example, a common trace width/space might be 6 mil (0.1524 mm) but smaller feature sizes are also common.
• Via Size and Placement
  Use appropriate via sizes and follow manufacturer guidelines for via placement. Incorrect via sizes or poorly placed vias can cause issues with drilling, plating, and ultimately impact the board's reliability. Always check the manufacturing capability of the PCB fab you plan to use, for example, some PCB fabricators have limitations on minimum drill size.
• Solder Mask and Silkscreen
  Ensure that your solder mask and silkscreen layers are well-defined and correctly positioned. Clearances around pads and vias in the solder mask layer are critical to avoid solder bridges. Ensure that the silkscreen is not overlapping pads, since this may lead to manufacturing errors. Inconsistent silkscreen text can lead to problems when identifying components.
• Board Dimensions and Outline
  Provide accurate board dimensions and a well-defined board outline. Ensure that the outline is closed and does not have any self-intersecting segments. This will help eliminate routing issues with the manufacturer's machines.
• Layer Stack-up
  Specify your layer stack-up precisely. Many online platforms offer standard stack-ups, but for complex designs, ensure your stack-up is manufacturable and is compatible with the materials available at your chosen manufacturer. The dielectric thickness and copper weight for each layer should be clearly defined.
• Panelization
  If panelization is required, clearly specify the panel arrangement, including any tooling holes or fiducials. If the panelization is performed incorrectly this may lead to issues when the boards are assembled.
• Design Rule Check (DRC)
  Run a thorough Design Rule Check (DRC) in your PCB design software to identify and correct design rule violations before submitting your design for fabrication. This can significantly reduce manufacturing issues. Pay close attention to clearance rules for components, traces, and vias.
