Related auxiliary devices need to be installed in semiconductor processing equipment to ensure the quality of semiconductor processed products.

[0003] The left and right sides of the existing KS gold-copper alloy wire bonding machine track are hollow, which is very easy to oxidize at high temperatures. On traditional equipment, there is only one aluminum plate on both sides of the working area to support the lead frame, which makes the frame easy to oxidize at high temperatures, affecting the quality of later product processing. Therefore, it is particularly important to design a clamp suitable for the sealing track of the KS gold-copper alloy wire bonding machine to solve the above technical problems. Utility Model Content

On traditional equipment, there is only one aluminum plate on both sides of the working area to support the lead frame, which makes the frame easy to oxidize at high temperature, affecting the quality of later product processing. A clamp suitable for the sealing track of the KS gold-copper alloy wire bonding machine is proposed.

[0006] Preferably, the left preheating cover plate includes a cover plate air blowing plate, a square air storage tank is arranged on the cover plate air blowing plate, air blowing holes are evenly distributed in the square air storage tank, and a cover plate top plate is installed above the cover plate air blowing plate.

[0007] Preferably, a gas nozzle joint is installed on the top plate of the cover plate, and the gas nozzle joint is connected to the square gas storage tank.

[0008] Preferably, the blowing holes are filled with nitrogen-hydrogen mixed gas.

[0009] Preferably, both the left preheating block and the right preheating block are made of high temperature resistant material.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] 1. In the utility model, during use, by installing preheating blocks on both sides of the lead frame and then installing a preheating cover plate structure on the outer side of the preheating block, a protective structure is formed on both sides of the lead frame, and then nitrogen-hydrogen mixed gas is transported to the position of the preheating block to form a protective gas on both sides of the lead frame. Compared with the conventional frame direct hollow structure design, the clamp adopted in the utility model forms good protection on both sides of the lead frame, and then combines the input of nitrogen-hydrogen mixed gas to form a protective gas layer.

[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0019] The utility model provides a clamp suitable for sealing the track of a KS gold-copper alloy wire bonding machine, comprising a right preheating block 1, a lead frame 2 is installed above the right preheating block 1, a left preheating block 3 is installed above the lead frame 2, a left preheating cover plate 4 is fixedly connected to the top of the left preheating block 3 by bolts 401, and a right preheating cover plate 5 is also fixedly connected to the bottom of the right preheating block 1 by bolts 401. The left preheating block 3 and the right preheating block 1 have a structure The left preheating cover plate 4 and the right preheating cover plate 5 are consistent in structure, the left preheating cover plate 4 includes a cover plate blowing plate 402, the cover plate blowing plate 402 is provided with a square gas storage tank 403, the square gas storage tank 403 is evenly distributed with blowing holes 404, a cover plate top plate 405 is installed above the cover plate blowing plate, the cover plate top plate 405 is installed with a gas nozzle joint 406, the gas nozzle joint 406 is connected to the square gas storage tank 403

[0020] When the fixture for sealing the track of the KS gold-copper alloy wire bonding machine is actually used, it enters the track from the lead frame 2 and is transferred to the working area. Because the whole is too long, the part not in the working area will be in contact with the air. Preheating blocks that can be blown are installed on the left and right sides. Specifically, they are divided into a left preheating block 3 and a right preheating block 1 structure, which can wrap up the hollow parts on both sides of the lead frame 2. The left and right preheating cover plates 5 are connected to the nitrogen-hydrogen mixed gas, and the gas is transported to the position of the preheating block through the gas nozzle joint 406, so that the gas forms a protective layer around the lead frame 2 to isolate oxygen and prevent the lead from being damaged. The frame 2 undergoes an oxidation reaction due to the high temperature of the track and the air. A preheating block is installed on both sides of the lead frame 2 and a preheating cover structure is installed on the outer side of the preheating block, so that a protective structure is formed on both sides of the lead frame 2. Then, a nitrogen-hydrogen mixture is transported to the position of the preheating block to form a protective gas on both sides of the lead frame 2. Compared with the conventional frame direct hollow structure design, the clamp adopted in the utility model forms good protection on both sides of the lead frame 2, and a protective gas layer is formed by combining the input of the nitrogen-hydrogen mixture. The overall structure of the clamp is compact and easy for the staff to install and maintain.

[0021] like Figure 1-3 As shown, the blowing hole 404 is filled with nitrogen-hydrogen mixed gas, and both the left preheating block 3 and the right preheating block are made of high temperature resistant material.

[0022] The effect achieved by the entire embodiment 1 is that, in use, the left preheating block 3 and the right preheating block 1 are made of high-temperature resistant materials, which makes it easy to conduct heat during actual working.

[0023] Working principle: When the lead frame enters the track and is transferred to the working area, the part that is not in the working area will come into contact with the air because the whole is too long. Preheating blocks that can be blown are installed on the left and right sides. They are specifically divided into left preheating block and right preheating block structures, which can wrap the hollow parts on both sides of the lead frame. The left and right preheating cover plates are connected to the nitrogen-hydrogen mixture, and the gas is transported to the preheating block position through the gas nozzle joint, so that the gas forms a protective layer around the lead frame to isolate oxygen and prevent the lead frame from oxidation reaction due to the high temperature of the track and the air.
