Description

Technical Field

[0001] The utility model relates to the technical field of IGBT substrates, and particularly relates to a visual arc detection device for IGBT substrate coding. Background Technique

[0002] The IGBT substrate is an important part of the IGBT module and plays a key role. The following is a detailed introduction for you: Main functions: Electrical insulation: When the IGBT works, it needs to perform switching operations under high voltage and large current conditions. The substrate can provide good electrical insulation to prevent problems such as current leakage and short circuit, ensuring the normal operation and safety of the circuit. Heat conduction and dissipation: A large amount of heat is generated during the operation of the IGBT. If the heat cannot be dissipated in time, it will cause the temperature of the IGBT to rise, affecting its performance and reliability, and even damaging the device. The substrate usually has a high thermal conductivity coefficient, which can effectively conduct the heat generated by the IGBT and play a role in heat dissipation, maintaining the normal working temperature of the IGBT. Mechanical support: Provide a stable mechanical support for the IGBT chip and other related components, ensuring that they can maintain a stable position and connection under various environmental conditions, and ensuring the integrity and reliability of the circuit.

[0003] When producing the IGBT substrate, it is necessary to detect the arc of the IGBT substrate and then perform marking. However, the existing processing devices only have one function of coding or arc detection, resulting in two steps for the arc detection and coding of the IGBT substrate, with low processing efficiency. Therefore, a visual arc detection device for IGBT substrate coding is proposed to solve such problems. Summary of the Utility Model
