Automobile air -conditioner actuator

The utility model relates to an automobile air -conditioner actuator, the electronic control apparatus comprises a circuit board, the circuit board includes the base plate and sets up the commutationcircuit on the base plate, commutation circuit is including silvering thick liquid circuit layer and spread the carbon film circuit layer at silvering thick liquid circuit layer upper surface, adoptssilvering thick liquid circuit layer to replace the copper foil circuit layer of executor circuit board in original technique, can the silver thick liquid fall to 0.01 with the residual resistance that the end -to -end connection place of carbon film produced 0.1 omega just so can improve the precision of carbon film to the precision that makes the rotation angle of executor improves, has possessed the requirement of high accuracy, silver paste layer's line structure is plated in the adoption, and the technology of plating silver paste layer is the same with the technology of plating the carbon film layer, just so can
