Problems solved by technology

[0002]The enameled wires of inductors in the prior art all use copper wire as the wire. The price of copper is very high and the weight is relatively large, so the material replacement of the wire is a It is a very important issue. Many people hope to use aluminum wires to replace copper wires. However, when aluminum wires are used, the inductors cannot be soldered to the circuit board at all. Therefore, replacing copper wires with aluminum wires is one of the existing technologies. problem

Embodiment 1

[0018] The inductor of this embodiment includes an iron core 1, an enameled wire 2 is wound around the iron core 1, the enameled wire 2 includes a wire and an insulating layer, the wire in the enameled wire 2 is set as an aluminum wire 4, and the connecting end 3 of the aluminum wire 4 is provided with a solder layer 5 . The solder layer 5 is set as a high melting point solder layer. The production method is as follows: first produce the aluminum wire inductor, then remove the paint film from the connecting end 3 of the aluminum wire, knock off the oxide layer of the aluminum wire, and hang high melting point solder at the same time, the inductor with this structure greatly reduces The cost of the inductor is reduced, and the welding problem of the aluminum wire inductor is solved, and the circuit board of the prior art can be freely welded as required, and can be widely used in electric appliances.

Embodiment 2

[0020] This embodiment is a production method for a circuit board provided with an inductor. The inductor is welded on the circuit board by soldering. The inductor includes an iron core 1, and an enameled wire 3 is wound outside the iron core 1. The enameled wire 3 includes a wire and an insulating layer, and the enameled wire 3 The inner wire is set as an aluminum wire 4 , and the connecting end 3 of the aluminum wire 4 is provided with a solder layer 5 . The solder layer 5 is set as a high-melting-point solder layer, and the melting point of the solder layer 5 is higher than the temperature of molten solder in the soldering equipment when the circuit board is soldered. The production process is as follows: first produce aluminum wire inductors, then remove the paint film on the connection end of the aluminum wire inductors, remove the oxide layer of the aluminum wires, and hang high melting point solder at the same time, and then connect the aluminum wires The terminal can b...

Abstract

The invention relates to an aluminum wire inductor and a method for producing a circuit board for arranging the inductor, and provides the aluminum wire inductor which can be easily welded to the circuit board by a general welding method and a general soldering tin, and the method for producing the circuit board for arranging the inductor. The inductor is welded to the circuit board by the soldering tin; and the method comprises the following steps of: producing the aluminum wire inductor; removing a paint film from the connecting end of an aluminum wire; after paint film removal, dropping off an oxidization layer on the surface of the aluminum wire, and suspending to the high-melting-point soldering tin; and welding the inductor in the former step to the circuit board by using the soldering tin. By the inductor and the circuit board for arranging the inductor, the cost of the inductor and the circuit board product is reduced effectively, the aluminum wire in the inductor can possibly replace a copper wire, and the inductor and the circuit board can be widely used in the field of electric appliances.

Description

technical field [0001] The invention relates to an aluminum wire inductor and a production method of a circuit board provided with the inductor. Background technique [0002] The enameled wire of the inductor in the prior art uses copper wire as the wire. The price of copper is very high and the weight is relatively large, so the material replacement of the wire is a very important issue. Many people hope to use aluminum wire to replace copper. wire, but after using aluminum wire, when the inductor is soldered to the circuit board, it cannot be soldered at all, so replacing copper wire with aluminum wire is a difficult problem in the prior art. Contents of the invention [0003] The present invention overcomes the above-mentioned defects and provides an aluminum wire inductor which can be easily welded to the circuit board by ordinary soldering tin and a production method of the circuit board provided with the inductor. [0004] The production method technical scheme of i...
