Description
Technical Field
The invention belongs to the technical field of microelectronic tools, and particularly relates to a deep cavity welding wedge-shaped riving knife material and a preparation method thereof.
Background
The wedge-shaped chopper is an important tool for the wire bonding process link in the integrated circuit production, and has the characteristics of small bonding wire distance, low bonding temperature, good bonding quality and the like. The special diagnosis size of the riving knife is small, and the tolerance requirement is strict, so that extremely high perforation machining precision is required when the riving knife is machined. Based on the existing numerical control processing punching equipment and technology, the numerical control processing technology is adopted to carry out punching processing on the riving knife, and a series of problems of low processing precision, high processing difficulty, low processing efficiency and the like exist. If the electric spark machining is adopted for threading the holes, the requirements on the depth-diameter ratio and the precision of the chopper machining can be met, but the machining time is extremely long, and the loss on the tool electrode is extremely high. The cost is high, the efficiency is low, and the method is not suitable for the production of a large number of riving knives. Moreover, the electric spark technology can only process vertical threading holes, and threading holes with transition structures cannot be directly prepared.
At present, the method for preparing the wire-hole rod with the transition structure mainly comprises a welding method and a compression molding method. The welding method is to connect and shape a plurality of parts which are processed separately through brazing. The method can prepare the riving knife bar with a complex threading hole structure, but has the advantages of complex processing process, long production period and weaker strength of the produced riving knife bar at the brazing joint. The pressing forming method is to lay powder in a pressed die, the die is provided with a die core with a transition structure threading hole, the powder is pressed to obtain a blank, and the blank is sintered to obtain a bar stock. The pressing forming method can obtain the riving knife bar with an integral structure, but has high precision requirements on a die and assembly, and is only suitable for preparing parts with simpler internal structures.
Disclosure of Invention

s4, sintering the presintered round bar obtained in the step S3 in vacuum to obtain a sintered round bar;
and S5, performing densification treatment on the sintered round bar obtained in the step S4, and performing hot isostatic pressing sintering in an argon atmosphere to obtain the deep cavity welding wedge-shaped chopper material.
Further, the powder of step S1Laser particle size D 50 0.1-35 μm.
Further, the solid acid in step S1 is one of boric acid, borax, succinic acid or maleic acid.
