Field of the Invention The present invention relates to a method of manufacturing a chip inductor 'and more particularly to a method of manufacturing a surface-mountable chip inductor for an electrical device.器 的 方法。 Method. 2. Description of Know-how. Chip inductors are used in various electrical devices such as electronic home appliances and electronic industrial equipment. Recently, in accordance with the trend toward miniaturization and weight reduction of various electrical devices, the electrical parts constituting the electrical devices have also been miniaturized and lightened. At the same time, based on the development of digital communication, the used frequency is gradually extended to the high-frequency region, so the electromagnetic wave environment has deteriorated. For process automation, most electronic devices are surface mounted on a printed circuit board. However, since the surface-mounting device is square, the conventional cylindrical inductor has difficulty in surface-mounting. Inductors are divided into winding type and stacked type, each of which has different application fields and manufacturing methods. In a wound inductor, a wire is wound around a substrate such as a magnetic material. In this case, when the number of windings is increased in order to obtain a high inductance, the high-frequency characteristics will be deteriorated based on the increase in the number of windings because a stray capacitance will occur between the wound coils. Meanwhile, in the stacked inductor, although the base system is the same as that of the wound inductor ', a green sheet having internal electrodes printed in a spiral shape is stacked instead of a wound wire. Pressing and sintering on this stacked green sheet 3 This paper is sized according to Chinese National Standard (CNS) A4 (210 X 297 mm) — — — — — — — — — — — Li II II Xiao Li I e I < Please read the notes on the back before filling out this page) 503408 v / f \ Instructions

On the contrary, because the number of stacked green sheets is limited, the inductance is also limited; and especially because the width of the internal electrode is limited, it is also limited to allow sufficient current. Therefore, it is not suitable for the stacked type Inductors are used in power devices, so their use is mainly limited to low voltage and low current. In addition, the method itself is extremely complicated and requires a lot of equipment costs. In order to solve the above problem, an inductor has been proposed, and its manufacture is formed by forming a metal layer on a cylindrical body and trimming the metal layer to form a line pattern on the metal layer, but because it is cylindrical Therefore, it is difficult to surface mount the manufactured inductor. In contrast, a square inductor is advantageous for surface mounting. However, a square inductor requires much time to trim the metal layer on the surface using a laser, which will increase the manufacturing cost. In addition, changes in the amount of laser light interruption will prevent the pattern on the inductor surface from being formed uniformly, thereby deteriorating its electrical properties. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a surface mountable chip inductor having excellent electrical properties. To achieve the above-mentioned object, a spiral pattern is formed on the surface of a cylindrical sensor body to facilitate manufacturing and improve electrical properties, and the cylindrical shape is deformed into a square to facilitate surface mounting. 4 This paper size applies Chinese National Standard (CNS) A4 Regulations (210 X 297 males) III ^ Installed! ----- Order ------- II (Please read the precautions on the back before filling this page) 503408 A7 _ B7___ V.

Description of the invention (1) The pulp part also has a spiral shape. The pitch between the metal coils is determined based on the width of the tape 40 wound around the periphery of the cylindrical body. In addition, the width of the metal coil formed on the periphery of the cylindrical body is determined by the distance between the expanded bands in the tape winding method. In addition, the thickness of the metal coil is almost determined by the thickness of the expanded tape itself. After forming the spiral metal coil on the periphery of the cylindrical body, the metal wire coil is hardened for a period of time. A method for manufacturing a spiral coil pattern according to a fourth embodiment of the present invention will now be explained. As shown in FIG. 5a, a linear flexible material 50 is wound around the periphery of the cylindrical body 10 in a spiral shape with a specific pitch. Here, a material such as nylon that cannot be penetrated by the conductive paste can be used as a flexible material. Next, as shown in FIG. 5b, in order to apply the conductive paste on the periphery of the cylindrical body, the cylindrical body 10 wound with the spiral flexible material will be dipped in a conductive paste 52 Container 51 for a while. And, the conductive paste coated on the cylindrical body 10 is hardened for a period of time. Since the conductive paste paddle 52 does not penetrate into the flexible material, the conductive paste coated on the cylindrical body has a spiral shape. It is preferable to remove the flexible material from the cylindrical body 10, and it is preferable that the conductive paste has a coating thickness not exceeding 1/2 of the diameter of the flexible material. In the second, third, or fourth embodiments of the present invention, it is preferable to use a flammable material for the flexible material and tape of the wire used to form the spiral coil, and it is also possible to use a non-flammable material as the Non-conductive material.

Second, as shown in FIG. 6b, the cylindrical body is Into a square mold, it is heated and pressurized to deform it into a square. As shown in FIG. 6b, the mold is divided into a lower mold 61 and an upper mold 62. The lower mold 61 is U-shaped due to the existence of the groove, and the cylindrical body can be inserted through the upper portion. After the cylindrical body is pushed in, the upper mold 62 is combined with the lower mold 61. In the present invention, since the mold is a square, the deformed body is also a square. However, depending on the type of surface mounting, the body can be deformed into a different shape. The cylindrical body can be deformed into the shape of a mold by pressing in the mold at a specific temperature. Because the cylindrical body contains a thermoplastic organic binder, it can be deformed by heating and pressing methods. In the present invention, after the outer coating layer is coated on the cylindrical body, the cylindrical body is deformed into a square body. It is also possible to apply 12 Chinese paper standard (CNS) A4 specifications (210 X 297 mm) — IIIIIIII — «Ili — ΙΙΙ 一« 4 (IIIII — — — * 1 ^ 1111111 ^^ (Please read the note on the back first) Please fill in this page again for matters) 503408 A7 ______ B7 _ 5. Description of the invention (U) The cylindrical body is deformed into a square, and then the outer coating layer is coated on the square body.
