A real Automotive Rain Sensor PCB is far more than reliable solder joints. Infrared light must pass through an air gap, a coupling medium, a lens, and the windshield, and a bubble or uneven adhesive layer at any interface shifts the optical path. Even if every electrical test is green, the sensor can still fail in the rain once installed in the vehicle. This small board forcibly merges the optical path with circuit design, which places demanding requirements on PCB manufacturing."}
