Dual chip multi-functional welding fixture

Abstract

The invention relates to a multifunctional welding jig for a double-wafer. The welding jig comprises a welding seat. A lower fixed electrode is installed in the center of the welding seat. An upper movable electrode is arranged above the lower fixed electrode. A first fixing seat and a second fixing seat are installed at the portions, located on the two sides of the lower fixed electrode, of the welding seat. A locating block and a locating frame are installed on the upper end face of the first fixing seat. An upper stop column is installed on the side face of the locating block. A lower stop column located below the upper stop column in a staggered manner is installed on the side face of the first fixing seat. The double-wafer is installed between the upper stop column and the lower stop column. A square tube end of a copper wire is installed between the double-wafer and the upper stop column and the other end of the copper wire abuts against the upper end of the locating frame. A locating column for limiting a supporting board and a locating calibration frame are further arranged on the side face of the first fixing seat. An end limiting frame is installed on the second fixing seat. The end of the end limiting frame is placed on the upper end face of the lower fixed electrode and abuts against the end faces of the double-wafer, a transverse board welding end and the square tube end.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding jig for double wafers. Background technique [0002] Such as Figure 7 As shown, the workpieces to be welded include a double chip 2, a copper wire 1 and a support plate 3, the copper wire 1 is curved, and its welding end is a square pipe end 101, and the support plate 3 is a multi-bend structure with an upper horizontal The welding end 301 of the plate, the middle bending part 302 in the middle and the lower bending part 303 in the lower part, the bending directions of the middle bending part 302 and the lower bending part 303 are opposite. At present, due to the lack of special welding fixtures, the three parts can only be welded separately by hand, the welding efficiency is low, and the welding quality is difficult to control; moreover, due to the multi-bending structure of the support plate 3, it needs to be calibrated and tested after processing. , At present, an...
