Abstract

The invention discloses an electric inductor manufacturing method.The method comprises the following steps that 1, an electric conductor is put into a mold; 2, the mold is filled with soft magnetic metal powder, and pressure is applied to integrally press the soft magnetic metal powder and the electric conductor into a pressed body; 3, heat treatment is performed on the pressed body, so that the soft magnetic metal material has the insulation resistance of the preset degree and releases the internal stress generated during pressing forming; 4, an oxidation layer, stretching out of the surface of the electric conductor, of the pressed body subjected to heat treatment is treated, so that welding and tin plating are conveniently achieved; 5, the electric inductor stretching out of a magnet is reshaped, so that needed surface attaching or inserting is conveniently achieved.The invention further discloses an electric inductor which is manufactured through the electric inductor manufacturing method.Accordingly, high-operating temperature, large-current, low-inductance value and high-automation level production of the electric inductor can be achieved, the quality of the electric inductor is improved, and the manufacturing yield of the electric inductor is increased.

Description

technical field [0001] The invention relates to a magnetic electronic component, in particular to an inductor and a manufacturing method thereof. Background technique [0002] With the development of semiconductor technology, the operating current of a single CPU is above 50A. For a DC-DC circuit that supplies power to a PC, the operating current of its surrounding power inductors is required to increase accordingly. At the same time, due to the requirement of high energy efficiency, the resistance value of the inductor is also required to be smaller and smaller, so as to reduce the heat generated by the current. At the same time, in order to miniaturize the device, the operating frequency of the inductor is also increased. At present, the mainstream frequency is 500KHz ~ 1MHz, and the common inductance range is 50nH ~ 680nH. At present, the current application and the high current power inductance of the circuit often use the following Two mainstream modes: [0003] One ...
