The process

How we coat your boards

  1. We pick the coating. The type depends on the environment your product faces.
  2. We mask what must stay clear. This includes connectors and test points.
  3. We apply the coating. We coat selected areas or the full board.
  4. We cure it.
  5. We inspect coverage. UV light shows gaps and thin spots.
  6. We fix any gaps before the board moves on.
Process control

Nano-coating and AI-assisted inspection

Where it makes sense, we use nano-coating. It needs much less masking, covers evenly at low thickness and takes less labor per board. It suits dense boards with many keep-out areas and products that change often.

Coating defects often show up late. We use AI-assisted inspection to find coverage gaps, edge voids, thin spots and masking errors early. It also makes pass and fail calls the same on every shift. Read more about our coating inspection.
