Method for fabricating nickel zinc ferrite integrated with PIN and dedicated smelting tool therefor

Abstract

The invention discloses a making method of nickel-zinc ferrite joint PIN product and specific treating tool to realize the method, which comprises the following steps: dripping glue in the contact pin hole of nickel-zinc ferrite magnetic core; plugging PIN in the contact pin hole of nickel-zinc ferrite magnetic core to form semi-product; putting the semi-product in one treat tool; placing the tool in the drying device; making the position of nickel-zinc ferrite magnetic core lower than PIN to keep inclination; connecting glue, PIN and nickel-zinc ferrite magnetic core together through micro-vibration in the thermostatic drying device; setting a row of magnetic core groove to suit the size of nickel-zinc ferrite magnetic core and PIN groove to suit the position of a row of magnetic core groove sequently with one end of magnetic core groove lower than one end of PIN groove at certain inclination.

Description

technical field [0001] The invention relates to an improved method for connecting a nickel-zinc ferrite power inductor to a PIN type magnetic core. The invention also relates to a special jig for the method. Background technique [0002] Since Oersted discovered the relationship between magnetism and electricity in the first half of the 19th century, magnetoelectric technology has been developing rapidly. It affects people's lives all the time. Nickel-zinc ferrite is a backbone of the development of modern magnetoelectric technology. It has been widely used in electronic equipment such as communications, electronic computers, and televisions. After China's accession to WTO, lead-free and lead-free products have become a basic condition for us to enter the international market. The pin (PIN) is a slender needle-like object. If the nickel-zinc ferrite core is connected to the PIN type magnetic core, it can be used without lead, and the solder resistance temperature must be i...

However, if it is placed on the cardboard for drying, the needle cap will come out, the glue will have air holes, and the residual gas in the glue will stay in the glue and not be discharged, and the needle will not be in place. In the use of downstream customers, the tension will be insufficient and the needle will fall due to gas expansion.

[0007] After using the dispensing machine, although the quality and output of the product have been improved to a certain extent, it has not yet achieved a very satisfactory effect. The output has reached 4000 pieces per day per capita. The quality statistics are shown in Table 2 below:
