The invention discloses a tooling fixture for cutting silver alloy bonding wire and its working method. The lead tube of the bonding wire, one end of the lead tube is provided with a clamping assembly for clamping the bonding wire, and a cutting assembly for cutting the bonding wire is arranged in the clamping assembly; the fixing plate One side of one side is fixedly connected with at least four sets of partitions, and a detachable pay-off assembly for placing bonding wire rolls is arranged between the partitions. In the present invention, at least four sets of baffles are fixedly connected on one side of the fixing plate, and a detachable pay-off assembly for placing bonding wire rolls is provided between the baffles, so that multiple sets of bonding wires of different types can be placed. The wire roll reduces the switching frequency of the bonding wire and improves the cutting efficiency of the bonding wire.
Description
Technical field [0001] The present invention belongs to the field of electronic equipment assembly technology, specifically relates to a kind of tooling fixture for cutting silver alloy bonding wire. It also involves a working method for cutting silver alloy bonding wires with work fixtures. Background [0002] Lead bonding dominates connection methods due to process simplicity, low cost, and a variety of package forms, with more than 90% of all package pins currently bonded. Bonding wire is a suitable for fine metal wire, the use of heat, pressure, ultrasonic energy to provide the ability of the electronic interconnection technology, lead bonding is a process that can be firmly welded, in this process, two metal materials (metal wire and substrate surface) tight bonding, once the surface is in close contact, there will be electron sharing or atomic mutual diffusion. [0003] In micro-assembly technology, there are often cases of coexistence of multiple wire diameter bonding wire...
