Welding heavy industry jig

Technical Field

The invention relates to the field of thermal processing of electronic components, in particular to a welding rework fixture.

Background

With the increasing progress of technology, the semiconductor industry is rapidly developing, and the development of electronic devices is also changing day by day, especially the progress of computer systems and their related peripheral industries is still a thousand days. Therefore, in consideration of pursuing portability and practicability, electronic components on the market generally tend to be light, thin, small and small so as to meet the life style of the modern society.

Generally, when an electronic device is operated, the electronic device itself generates heat to raise the ambient temperature of the whole system, which results in a decrease in the stability of the system and even a failure. Therefore, a heat sink is required to maintain the system operating at a stable ambient temperature. There are many types and types of heat sinks, and the most common heat sink is a metal structure attached to the surface of an electronic device, which can dissipate heat quickly due to the high thermal conductivity of the metal.

However, when the pin elements in the ATA interface are heated, because the ATA interface is long and the pins in the interface are dense, inconvenience is brought to heating, if the heating tube is set to be long along with the length of the interface, the heat will be dispersed, the heating effect is not ideal, and if the heating tube is short, the elements in the ATA interface need to be heated several times, but the movement of the heating tube in the ATA interface is influenced by the pins, which is not favorable for completing the heating process. It is a current problem to design a device that is suitable in heat pipe length and can be conveniently moved in the ATA interface.

Furthermore, the two groups of turned edges are symmetrically arranged on the side wall of the lower box body, the turned edges are of an L-shaped structure, and the two groups of turned edges are symmetrically bent towards the inner side of the side wall.

Further, the heating method of the welding rework fixture comprises the following steps:

step 1, butting the caking of the heater and the upper box body, pressing the jig to an ATA interface by holding the heater by hand, enabling the lower box body of the jig to collapse downwards under the pressure, enabling the part of the upper box body inserted into the lower box body to move downwards under the stress until pins in the ATA interface are covered by a cage, enabling two groups of symmetrical flanging on the outer side of the lower box body to simultaneously contract inwards under the stress, enabling the pin through holes on the side wall to be sealed, and achieving the heat gathering effect in the lower box body;

and 2, after the ATA interface part is heated, recovering the pressure, restoring the lower box body, removing the sealing state of the pin perforation at the moment, after hot air in the lower box body is released, moving the handheld heater to the next heating position along the length direction of the ATA interface, and repeating the heating step in the step 1, wherein in the moving process, the pins in the ATA interface pass through the pin perforation.

Compared with the prior art, the invention has the following advantages:

the scheme of the invention ensures that the heating device can conveniently move in the ATA interface and has the advantages of quick heat accumulation, good sealing and high heating efficiency.
