circuit wafer

The invention relates to a radiator fan, which comprises a fan frame, an inner rotor motor, at least an impeller and a circuit wafer.

The print circuit wafer uses the vanguard technology and the equipment production with the processing glass cloth, has the fine electric insulation performance and workability.

When installs, If the metal falls on the product circuit wafer, because have not the insulating layer to cause the electric circuit to short-circuit, easy to burn out the product;
