Collector motor speed controller with tachodetector on TDA1085C

The collector motor speed controller boards for the TDA1085C were received 2 weeks after shipment. The quality of manufacturing and metallization of the holes is excellent, the thickness of the copper layer corresponds to the ordered one, silkscreen printing as well as the quality of applying the protective mask are excellent. The final coating is uniform and of the same thickness. Printed tracks have a stable width and thickness. Packed very high quality in vacuum packaging and box. Instead of 10 printed circuit boards, they put 11. Everything is fine, I recommend it.
