Problems solved by technology

[0002] The existing inductance structure is mainly soldering the junction of the coil and the terminal manually. On the one hand, this mode of operation has particularly high requirements for personnel during the welding process, and personnel are prone to make mistakes during operation, and accidents are prone to occur. On the other hand, the use of tin soldering increases the cost of the enterprise, which is not conducive to the expansion and reproduction of the enterprise. Most of the existing SMD inductor device cores are directly exposed, lacking corresponding protection, resulting in the heat resistance of the inductor. The impact ability, moisture resistance and vibration resistance are poor, which cannot meet the needs in actual operation

Abstract

The invention provides an SMD inductance device with a magnetic rubber coating iron core and a processing technology thereof. The SMD inductance device with the magnetic rubber coating iron core comprises a substrate, one end of the substrate is plated with a silver paste layer, sunk parts of the substrate and the silver paste layer are wound with enamelled copper wires which are plated with a protection coat, and the protection coat is composed of plastic BASE materials. According to the SMD inductance device with the magnetic rubber coating iron core and the processing technology thereof, on one hand, the good effect of protecting the enamelled wires is achieved; on the other hand, a good induction effect in the actual operation is achieved; damage to electronic products caused by an instantaneous excessive current can be prevented.

Description

technical field [0001] The invention relates to the field of inductance parts, in particular to an SMD inductance device with a magnetic glue-coated iron core and a processing technology thereof. Background technique [0002] The existing inductance structure is mainly soldering the junction of the coil and the terminal manually. On the one hand, this mode of operation has particularly high requirements for personnel during the welding process, and personnel are prone to make mistakes during operation, and accidents are prone to occur. On the other hand, the use of tin soldering increases the cost of the enterprise, which is not conducive to the expansion and reproduction of the enterprise. Most of the existing SMD inductor device cores are directly exposed, lacking corresponding protection, resulting in the heat resistance of the inductor. The impact ability, moisture resistance and vibration resistance are poor, which cannot meet the use in actual operation. Contents of ...
