Abstract

The invention discloses a chip eutectic welding equipment, specifically relates to the field of chip processing technology, comprising a base and a column, one side of the top of the base is fixedly connected with a column, the interior of the column is provided with an adjustment mechanism, and the column One side is fixedly connected with a dust suction mechanism, and the other side of the column is provided with a cross bar. The present invention is provided with a chute, an adjustment block, a suction cup, a baffle and a central axis. When the traditional welding device clamps and fixes the chip, it is easy to cause damage to the corner of the chip. It is installed on the top of the worktable for processing. Several groups of suction cups, place the chips on the top of the suction cups and press down gently, the chips can be placed on the suction cups stably, and the angle between the baffles outside the central axis can be adjusted according to the width of different chips. The angle of the baffle can be adjusted by moving the adjustment block, so that fixing the chip can avoid damage to the corners caused by hard objects clamping the chip.

Description

technical field [0001] The invention relates to the technical field of chip processing, in particular to a chip eutectic welding device. Background technique [0002] Chip processing needs to be packaged and welded. The existing packaging and welding technology includes eutectic welding technology. Eutectic welding technology has the advantages of fast heat transfer and strong adhesion, so it is the most widely used electronic packaging technology. The eutectic soldering technology still has some deficiencies when it is used. For example, when the chip is soldered, sometimes there is too much tin, and some tin remains on the surface of the chip during soldering and cannot be cleaned, or the soldering head of the device used for soldering cannot be cleaned. Disassemble and replace, once the welding head fails, the whole device cannot be used. [0003] In the process of realizing the present invention, the inventors have found that at least the following problems in the prior...
