Abstract

The invention discloses a thin inductor structure and a manufacturing method thereof. The thin inductor structure comprises a coil, two electrode tips, a first magnetic conductive plate, a second magnetic conductive plate and a body, wherein the coil comprises two pins; the two electrode tips are electrically connected with the two pins respectively; the first magnetic conductive plate is arranged between the two electrode tips and is located below the coil; the second magnetic conductive plate is arranged above the coil corresponding to the first magnetic conductive plate; and the body coats the coil and sticks the first magnetic conductive plate, the second magnetic conductive plate and the two electrode tips. The two pins of the coil are temporarily adhered to the two electrode tips of a preset customized lead frame by directly utilizing tin paste; tin paste melting is carried out in a reflow oven; and the two pins of the coil and the two electrode tips on the lead frame are welded and fixed, so that welding actions do not need to be carried out one by one between the two pins of the coil and the two electrode tips on the lead frame; the target of simplifying the process is reached; the work efficiency is effectively improved; and the output benefits are improved.

Description

technical field [0001] The invention relates to the technology in the field of inductors, in particular to a thin inductor structure and a manufacturing method. Background technique [0002] In the known thin inductor structure, although there are many types of bodies, the connection and fixation between the coil in the structure and the first wire and the second wire end on the lead frame are all done by welding, for example, as shown in the figure below : U.S. No. 6,204,744 patent of invention, please refer to shown in its No. 1B figure and No. 1 C figure, can see the lead frame 32 of the first lead 16 on the lead frame 32 and the lead frame 32 of the second lead 18 in the figure The two ends 34 , 38 are combined and fixed with the inner end 26 and the outer end 28 of the coil 24 respectively by means of welding. In addition, as shown in Figures 3, 4, and 5 of Taiwan Approved Publication No. 201234395 Patent, the two folded legs 1 1 of the conductive coil 1 0 and the weld...
