[0002] High-speed electronic switching semiconductor devices are semiconductor components that can quickly control the on and off of circuits. They are widely used in modern electronic technology. Common high-speed electronic switching semiconductor devices include high-speed switching diodes, MOSFETs, and IGBTs.
[0003] The patent application with application number CN201720256249.8 discloses a high-speed power switching device, including a control signal input terminal, a first switch connection terminal, a second switch connection terminal and a high electron mobility transistor, the high electron mobility transistor including a substrate; a semiconductor layer located on the substrate, wherein the semiconductor layer includes a heterostructure, the heterojunction forms a two-dimensional electron gas, a groove is formed on the semiconductor layer in the gate region, and the thickness of the semiconductor layer below the groove is greater than the thickness that meets the conditions of an enhancement-mode transistor; a source and a drain located at both ends of the semiconductor layer, the source being electrically connected to the first switch connection terminal, and the drain being electrically connected to the second switch connection terminal; a first dielectric layer located in the groove; a floating gate located on the first dielectric layer; a second dielectric layer covering the floating gate and the first dielectric layer; a control gate located on the second dielectric layer, the control gate being electrically connected to the control signal input terminal.
[0004] During the soldering and installation process of existing high-speed electronic switching semiconductor devices on circuit boards, external solder connections are generally used. This traditional installation mode can easily lead to uneven solder distribution, resulting in welding stress concentration, insufficient interface bonding strength, and a high probability of cold solder joints in the finished welding product, which in turn affects the electrical connection reliability of the circuit board and may eventually cause operational failure of the entire circuit system. Summary of the Invention
[0005] In view of the deficiencies of the prior art, the present invention provides a high-speed electronic switch semiconductor device to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a high-speed electronic switch semiconductor device, comprising a semiconductor, wherein the outer wall of the semiconductor is provided with a first slide groove, the outer wall of the first slide groove being fixedly connected to a right-angle plate, and further comprising: The connecting mechanism comprises a connecting plate movably connected to the inner wall of a slide groove, the inner wall of the top of the connecting plate is fixedly connected to an embedded plate, the outer wall of the embedded plate is movably connected to the right-angle plate, the inner wall of the embedded plate is fixedly connected to a tin plate one, the bottom of the connecting plate is fixedly connected to the shell, the bottom of the shell is provided with a cross groove, the top of the shell is provided with a slide groove two, the inner wall of the shell is movably connected to a movable component, the cross groove opens up the bottom of the shell to facilitate the passage of tin, thereby enhancing the fixing effect, and by setting the connecting mechanism, the solder is pre-placed inside the connection interface, and no additional external solder is required during the welding process. This structure enables the solder to be evenly distributed on the connection interface between the shell and the circuit board, effectively enhancing the mechanical strength and electrical conductivity of the connection part, reducing the quality defects such as cold soldering and false soldering common in traditional welding methods, thereby improving the connection reliability and long-term operation stability of the equipment.
[0007] According to the above technical solution, a U-shaped groove 1 is provided on the top of the shell, a U-shaped groove 2 is provided on the outer wall of the shell, a right-angle groove is provided on the outer wall of the shell, and a heat-conducting component is fixedly connected to the inner wall of the right-angle groove. The multiple notches of the shell allow the heat-conducting component to be embedded in the shell, thereby controlling the direction of heat transfer.
[0008] According to the above technical solution, the bottom of the shell is fixedly connected with a raised ring, and the outer wall of the raised ring is fixedly connected with a soldering rod. After heating, the soldering rod will flow to the bottom of the shell, thereby enhancing the soldering effect of the bottom.
[0009] According to the above technical solution, the side of the right-angle plate away from the slide groove is fixedly connected to the heat conducting plate 1, and the outer wall of the slide groove is fixedly connected to the serrated plate. The heat conducting plate 1 is used to transfer temperature and melt the tin plate 1. By setting a connecting mechanism, when the semiconductor is damaged, there is no need to replace the entire equipment, and only the semiconductor needs to be disassembled separately. This reduces the difficulty and technical requirements of the welding operation, shortens the equipment maintenance time, and improves the maintenance efficiency.
[0010] The U-shaped slot is fixedly connected to the bottom of the heat-conducting right-angle rod, and the outer wall of the heat-conducting right-angle rod is fixedly connected to the U-shaped slot. The top of the heat-conducting right-angle rod is fixedly connected to the U-shaped rod. The outer wall of the heat-conducting U-shaped rod is fixedly connected to the U-shaped slot. The U-shaped rod transfers the temperature to the U-shaped rod, melting the soldering rod. By setting the heat-conducting component, when the top of the connecting mechanism is heated, the heat is transferred to the periphery of the shell through the heat-conducting component, causing the soldering rod to melt due to the heat. Under the action of gravity, the molten flux automatically fills the connection gap between the shell and the circuit board to form a sealing layer, effectively isolating the air and preventing oxidation of the welding part. The uniform distribution of the flux ensures the integrity of the welding interface and improves the connection reliability.
[0011] According to the above technical solution, the movable assembly includes a movable plate, the outer wall of which is movably connected to the outer shell. The bottom of the movable plate is fixedly connected to a second tin plate. After being melted by high temperature, the second tin plate is used to fill the gap between the outer shell and the circuit board. By setting up the movable assembly, during the soldering process, the pre-installed second tin plate is heated and melted. However, due to the surface tension of the tin itself, it is difficult to completely fill the right-angle gap between the outer shell and the circuit board by gravity alone. To this end, a controllable vertical downward force can be applied to the molten tin to ensure that the molten tin fully fills the connection gap, improving the integrity and connection strength of the soldering interface, thereby ensuring the reliability and stability of the soldering quality.
[0012] According to the above technical solution, a ramp plate is fixedly connected to the top of the movable plate, a through groove is provided on the outer wall of the movable plate, and a strip groove is provided on the top of the ramp plate. The strip groove passes through the ramp plate and extends to the inner wall of the through groove. When the ramp plate is subjected to pressure, it will move downward, thereby flattening the tin material.
[0013] According to the above technical solution, the inner wall of the ramp plate is fixedly connected to the heat-conducting strip 2, the bottom of the heat-conducting strip 2 is fixedly connected to the heat-conducting strip 1, the outer wall of the heat-conducting strip 1 is fixedly connected to the strip groove, the bottom of the heat-conducting strip 1 is fixedly connected to the heat-conducting plate 3, the outer wall of the heat-conducting plate 3 is fixedly connected to the heat-conducting plate 2, and the outer wall of the heat-conducting plate 2 is fixedly connected to the through groove. The heat-conducting strip 1 is used to transfer heat, thereby accelerating the melting speed of the tin plate 2.
[0014] Compared with the prior art, the present invention provides a high-speed electronic switch semiconductor device with the following beneficial effects: 1. The present invention pre-places solder inside the connection interface by providing a connection mechanism, eliminating the need for additional external solder during the welding process. This structure allows the solder to be evenly distributed at the connection interface between the housing and the circuit board, effectively enhancing the mechanical strength and electrical conductivity of the connection, and reducing quality defects such as cold solder joints and false solder joints that are common in traditional welding methods, thereby improving the connection reliability and long-term operational stability of the equipment.
[0015] 2. The present invention provides a heat-conducting component. When the top of the connecting mechanism is heated, the heat is conducted to the periphery of the shell through the heat-conducting component, causing the soldering rod to melt. Under the action of gravity, the molten soldering flux automatically fills the connection gap between the shell and the circuit board to form a sealing layer, effectively isolating the air and preventing oxidation of the welding part. In addition, the uniform distribution of the soldering flux ensures the integrity of the welding interface and improves the connection reliability.
[0016] 3. This invention incorporates a movable assembly. During the soldering process, the pre-placed tin plate 2 melts due to heat. However, due to the surface tension of the tin itself, gravity alone cannot completely fill the right-angle gap between the housing and the circuit board. Therefore, a controllable vertical downward force is applied to the molten tin, ensuring that the molten tin fully fills the connection gap, improving the integrity and strength of the soldering interface, thereby ensuring the reliability and stability of the soldering quality.
[0017] 4. By setting up a connecting mechanism, the present invention does not need to replace the entire device when the semiconductor is damaged. It only needs to disassemble the semiconductor separately, which reduces the difficulty and technical requirements of the welding operation, shortens the equipment maintenance time, and improves the maintenance efficiency.
