Description
Technical field
The utility model relates to a kind of pellet bonding machine bonding clamper active window open flume type fixation kit.
Background technology
In semiconductor package process, on chip, the conduction of electrical property is by routing procedure, utilizes metal bonding wire to conduct on carrier, substrate etc. the signal on chip, then is connected on printed circuit board (PCB) by outside terminal.And in bonding wire operation lead frame fixedly need fix lead frame by bonding clamper, its wire welding area well can be fixed, therefore effectively can control routing procedure, assist semiconductor packages high yield.Pressing plate window is in the past (see Fig. 1) of being fixed on pressing plate, brings limitation (pressing plate is heated or stressed rear distortion) to the adjustment of pressing, and the pressing plate of this integral type just can not good pressing lead frame, the window member of current existing bonding clamper is dismantled and assembled (see Fig. 2), its stationary window parts are fixed by the triangle spring leaf of the monomer-type respectively in window both sides, its fixing point is that hemispherical links closely, every side due to window member only has a fulcrum to fix, and fixing fulcrum is positioned on the center line of window member, if the irregular words of the leadframe surfaces below window member can cause window member cannot active balance, there will be the problem of seesaw, thus cause lead frame well not fixed, and its spring leaf only has one at the stress point of apex, that the reaction force that is subject to is larger in pressing, there is limitation in the stability of spring leaf, in addition the single spring pressure in current single window left and right, when Spring deformation degree is different, tilting part does not limit, and may affect the effect of fixture pressing.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of pellet bonding machine bonding clamper active window open flume type fixation kit is provided, it adopts integrated spring piece to design, and spring leaf is fixing more convenient, and active window adopts multi-point support, window is fixing more to be balanced, thus lead frame pressing better effects if, there will not be the problem that local tilts, the stability of spring leaf is better, add the life-span of spring leaf, and reduce manufacturing cost.
The purpose of this utility model is achieved in that a kind of pellet bonding machine bonding clamper active window open flume type fixation kit, it comprises top board carrier, described top board carrier is provided with first step, described first step is provided with second step, described second step is provided with pressing window, the described pressing window left and right sides is provided with spring leaf, described spring leaf is arranged in first step, fixed head is provided with above described spring leaf, described spring leaf is connected with top board carrier by flat head screw with fixed head, described spring leaf is arranged with many flutings in parallel near pressing window side, spring leaf is divided into multiple pressure tongue near pressing window side by described many flutings, described pressure tongue front bottom end is provided with salient point.
Described fixed head bottom inside is provided with the 3rd step.
Described salient point bends downwards by pressure tongue end or the mode of electric welding is formed.
Compared with prior art, the utility model has following beneficial effect:
A kind of pellet bonding machine bonding clamper of the utility model active window open flume type fixation kit, its manufacture is convenient, it adopts integrated spring piece to design, and spring leaf is fixing more convenient, and active window adopts multi-point support, window is fixing more to be balanced, thus lead frame pressing better effects if, there will not be the problem that local tilts, the stability of spring leaf is better, add the life-span of spring leaf, and reduce manufacturing cost.
