Abstract
Description
technical field
[0001] The present invention relates to an improved manufacturing process of thin power inductors, especially refers to the helical inductance coil of the power inductance, which is shielded with metal, and is made in conjunction with the sputtering process and copper electroplating process, and the outer surface of the formed spiral inductance coil is passed through The colloid of the magnetic material configuration is printed to form an insulating coating layer. Background technique
[0002] Existing power inductors are formed by using wires with a rectangular or circular cross-section and winding them into a helical inductance coil. The helical inductance coil has a plurality of coils extending in layers along the vertical direction, and its two ends are respectively connected with wires to connect with external electrodes. When making, put the helical wire that has been welded into the mold first, inject magnetic powder material into the mold, press the ...
