As the core power device of modern power electronic systems, the manufacturing quality of IGBT directly determines the energy conversion efficiency and equipment reliability. Leveraging its deep vertical integration capabilities, HOLS not only provides nano-precision potting equipment (with glue thickness control of ±0.1mm), but also delivers an intelligent production line solution covering the entire IGBT module manufacturing process, including critical stages such as frame assembly, hermetic encapsulation, and functional testing. The technical highlights are as follows:

1. Full-process integration process chain, the production line integrates seven core stations with precision assembly: automated substrate loading (with a positioning accuracy of ±0.05mm), plasma surface activation, high-precision sealant coating, DCB substrate bonding, frame thermocompression welding, multi-axis collaborative locking (torque control of 0.3-3Nm), and intelligent sorting of finished products (AOI defect detection rate > 99.98%).
2. Production environment and data management: Firstly, the cleanroom compliance: The entire line meets ISO Class 6 cleanroom standards (particle concentration ≤ 35200/m³), compliant with automotive-grade IGBT manufacturing requirements (e.g., AEC-Q101). Secondly, full lifecycle traceability: QR code labeling integrated with the MES (Manufacturing Execution System) enables real-time archiving and traceability of process parameters (e.g., welding temperature profiles), material batches (DCB substrate traceability codes), and test data.
3. Equipment efficiency optimization: In terms of space utilization, HOLS adopts a multi-layer tunnel curing oven (saving 40% of floor space) and a high-efficiency cooling system (cooling rate ≥ 15°C/min) to work in tandem, significantly increasing the single-line production capacity. Regarding to energy consumption control, HOLS independently develops a thermal energy recovery device (efficiency > 65%) and variable frequency drive technology (energy-saving rate of 30%) significantly reduce operating costs.
