This overmolded printed circuit board is part of an actuator cable. It makes an existing actuator addressable. The best way was to mold the small PCB with processor into the connector of the actuator.
This overmolding process is very delicate. The reason is there are 4 overmolding steps. In each step we can damage the PCB and as such ruin the product. Each manufacturing step requires precision tools and skilled operators. After each step we test the functionality of the PCB.
