A making method for fully automated small ultra-thin chip inductor

Abstract

This invention relates to automatic small film slice induction process method, which comprises the following steps: a, arraying copper material band onto inductor bottom; setting folded wire end and small protruding bench on each weld board and impacting position hole on band part; b, sticking I-shaped iron core onto center of inductor; c, rolling coil with two ends of coil onto roller ends; d, welding by laser on rolling coil; e, spraying glue onto iron core; f, combing hollow iron chip; g, spraying glue; h, printing; I, cutting along isolation hole two ends; j, testing and packing.

Description

【Technical field】 [0001] The invention relates to a manufacturing method of an inductor, in particular to a fully automatic manufacturing method of a small ultra-thin chip inductor. 【Background technique】 [0002] At present, people adopt manual production when making small ultra-thin chip inductors (as shown in Figure 1), and its production efficiency is low, and its technology is like this: a), stick the hollow iron core 100 on the copper On the band terminal 200; b), winding the coil 400 on the I-shaped iron core 300; c), flipping the I-shaped iron core 300 with the coil 400 in the hollow iron core 100; The two ends of the coil 400 are on the copper strip terminal 200 on both sides respectively; e), soldering tin—take the copper strip terminal 200 in the tin furnace for welding; f), print on the surface of the I-shaped iron core 300; g), test, Package. This method has the following disadvantages: ①. Since this production method requires tin furnace welding, it will caus...

[0002] At present, people adopt manual production when making small ultra-thin chip inductors (as shown in Figure 1), and its production efficiency is low, and its technology is like this: a), stick the hollow iron core 100 on the copper On the band terminal 200; b), winding the coil 400 on the I-shaped iron core 300; c), flipping the I-shaped iron core 300 with the coil 400 in the hollow iron core 100; The two ends of the coil 400 are on the copper strip terminal 200 on both sides respectively; e), soldering tin—take the copper strip terminal 200 in the tin furnace for welding; f), print on the surface of the I-shaped iron core 300; g), test, Package

This method has the following disadvantages: ①. Since this production method requires tin furnace welding, it will cause certain damage to the copper wire coil of the product during tin furnace welding, so that some of the inductance products produced will have poor copper wire short circuits. situation, which will ultimately affect the reliability of the product

②. At the same ti
