Embodiment Construction
[0030] Magnetic core of the present invention, chip inductor with magnetic core and manufacturing method thereof, the magnetic core of the first preferred embodiment of the present invention is as Figure 1 to Figure 3 As shown, make as Figure 1-3 The shown magnetic core 2, the magnetic core 2 is composed of non-conductive ferromagnetic material such as ferric oxide, and the side view is like a letter I. The basic structure includes a top 22, a base 23, and a depression connecting the top 22 and the base 23 Winding part 24. Among them such as image 3 As shown in the perspective view of the bottom, the outlines of the top 22 and the base 23 are larger than the outline of the concave winding portion 24 (broken oval line). The uppermost surface of the top 22 is an adsorption plane 220 , which is used to facilitate the adsorption and movement of the suction nozzle of the mechanical arm when the inductance element is finally formed and surface-mounted to the circuit board.
