Alloy framedeformation correction jig

Abstract

The invention discloses an alloy frame deformation correction jig. The correction jig comprises a lower closing die, an upper closing die is arranged on the upper side of the lower closing die, a middle closing die is arranged between the lower closing die and the upper closing die, a limiting groove is formed in the upper end of the middle closing die, a plurality of alloy frames are arranged in the limiting groove and are arranged in order, the alloy frames are arranged in the limiting groove, on one side of each alloy frame, the lower closing die and the upper closing die are pressed up and down, and a cushion position bottom groove is formed in the upper end of the lower closing die. The three module mechanisms of the lower closing die, the upper closing die and the middle closing die are used for pressing the alloy frame up and down, limiting the position of the alloy frame, conducting post-curing treatment of heat preservation and correcting the alloy frame, so the effect of correcting the alloy frame after deformation is achieved, the problem of deformation of the alloy frame caused by expansion coefficients of different materials in the packaging process is solved, and the production yield of products is greatly improved, therefore, the productivity is improved, and the economic benefits of enterprises are increased.

Description

technical field [0001] The invention relates to the field of correction fixtures, in particular to a correction fixture for deformation of an alloy frame. Background technique [0002] Alloy chip resistors are made of special alloys that meet high-power electrical characteristics, high purity, high thermal conductivity, low-temperature drift and high-temperature resistance, and are integrally formed without cutting, which greatly reduces the heat dissipation area on the circuit board and can achieve almost no inductance. As a current carrier, alloy resistors have precise resistance, temperature stability, product safety, and stability are significantly higher than ordinary ceramic resistors. At the same time, the thermal conductivity of metal is also a major advantage over other resistors. Especially in the application of power supply and other related products, when instantaneous inrush current, short circuit current or pulse current is generated, the alloy is the first ch...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to propose a correction fixture for alloy frame deformation, which aims to solve the problem of the large difference between the thermal expansion coefficient of epoxy resin and the thermal expansion coefficient of the alloy in the existing packaging process of alloy chip resistors. After the plastic sealing is completed, the alloy frame will bend sideways in the lateral direction, which will affect the production of the subsequent process and seriously affect the pass rate of the product, resulting in a large waste of material resources and increasing the operating cost of the enterprise
