When you finish your PCB design, you may think it can be made directly. But many designs have DFM problems, the factory can not produce it well.

DFM means Design for Manufacturability. It is the rules to make your board easy to produce.

Here are some common DFM mistakes we see every day:

  1. Trace width and space too small. If the line is too thin, copper may break. Small gap will cause short circuit.
  2. Pad size not match component. Pads too small, the part can not solder well.
  3. No enough clearance near hole and slot.
  4. Copper area without thermal relief, easy to have bad soldering.
  5. Outline too close to traces, easy damage when cutting.

These small problems will make your PCB sample rejected. You need rework design, waste time and money.

If you are not sure your design is ok, you can send your Gerber file to us. We can check DFM for you before production.
