The packaging and soldering process provides physical protection by encapsulating the chip in a shell with mechanical strength and temperature resistance, preventing damage to the chip from factors such as vibration, humidity, temperature changes and mechanical stress.

[0003] Welding equipment needs to limit and fix integrated circuits to ensure the accuracy of welding processing. However, the internal connection force of the pressure plate structure in current welding equipment is limited. After long-term use, the balance of the pressure plate is easily reduced, resulting in the inability to provide stable pressing force and causing compression to the integrated circuit.

[0004] Therefore, a novel pressure plate structure for an integrated circuit packaging wire bonding machine is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure plate structure for an integrated circuit packaging wire bonding machine, including a base, connecting seats fixedly connected to both sides of the top of the base, baffles fixedly connected laterally to the front and rear ends of the top of the base, and a strong connection limiting component provided on the inner side of the connecting seat;

[0007] The limiting component includes a pressure plate. The inner side of the connecting seat is recessed with a circular groove. A circular rod is fixedly connected to the inner wall of the circular groove. A socket is sleeved and fixed to the front and rear ends of the circular rod. The socket passes through the side wall of the connecting seat laterally. A guide hole is opened through the inner side of the socket. An adjusting screw is threaded through the inner side of the guide hole. The top end of the pressure plate is movably connected to the bottom end of the adjusting screw.

[0008] As a further technical solution of this utility model, a first knob is fixedly connected to the top of the adjusting screw, the two sets of pressure plates are symmetrically distributed about the vertical center line of the base, and an anti-slip pad is fixedly connected to the bottom of the base.

[0009] As a further technical solution of this utility model, the front end and the rear end of the base are fixedly connected to an external plate, and the two sides of the external plate are symmetrically fixedly connected to a fixed seat. The inner end of the fixed seat is fixedly connected to the outer end of the base. The top and bottom of the outer end of the fixed seat are fixedly connected to a fixed block. The outer end of the fixed block is fixedly connected to a limit frame, and the limit frame is sleeved on the outside of the fixed seat. The inner end of the limit frame is fixedly connected to the outer end of the base.

[0010] As a further technical solution of this utility model, fastening bolts are vertically arranged through both sides inside the outer plate, and a second knob is fixedly connected to the top of the fastening bolts.
