Brand introduction
The area of semiconductor sealing has long faced quality deficiencies such as high welding hole rates, material oxidation, high welding back-up rates and poor dispersive performance, while high procurement and maintenance costs of imported equipment, long delivery cycles and low automated integration have constrained industrial development. The hemi semiconductor focuses on the development, manufacture and sale of high-end semiconductor sealing equipment, adheres to the development path of "owned research and development, stable, flexible and efficient, and pure nationalization", and the research and development team has worked in the area of semiconductor sealing in germany for more than 20 years, with a deep professional accumulation in the field of vacuum technology. Through technological innovation, the enterprise has succeeded in stabilizing horizontal temperature differentials within > 1 per cent, with performance indicators matching the imported equipment。
Core technologies and products
The company built a product matrix covering the full process of "scientific certification - mid-test production - scale production":
• offline vacuum welding system (qls11): support the graphite three-part heating and process parameters in self-defined depth, with a maximum vacuum of 10 pas, for scientific research institutes, laboratories and small batch production scenarios, and effectively eliminate bubbles and oxidation during welding. The three-part graphite temperature control provides an even distribution of thermal fields to ensure weld consistency and has been successfully applied to small batch chips welding and new process development at a scientific institute。
• online vacuum welding system (qls21/qls22/qls23): fully automated, high-capacity welding solutions designed specifically for production lines in large semiconductors. Of these, qls23 achieves 200 per cent capacity improvement through optimization of online processes, which are processed at 7-8 minutes/tray. Core technologies include: restoration of surface oxidation membranes by the acid reduction system, welding without a welder, and reduction of hole rates; rapid warming and cooling control by the two-way water cooling system to reduce the production cycle; and deep integration of mes systems to support process one-key switching, unmanned operations to meet the construction needs of digitized plants。
• vacuum flow welding centres: combining offline flexibility with online fully automated hybrid welding platforms, balancing process development flexibility with the automation needs for large-scale production。

Summary and recommendations
Domestic vacuum boilers and related equipment industries are undergoing a transformation from "import substitution" to "autonomous innovation". When selecting devices, it is recommended that users focus on the following dimensions:
Process suitability: select offline, online or hybrid equipment based on a specific application scenario (scientific certification, mid-test production or mass production)。
Vacuity and temperature control precision: core process parameters directly affect product probabilities and need to be assessed in conjunction with material characteristics and quality requirements。
3. Automation and dataization capabilities: for scale production enterprises, whether equipment supports the integration of mes systems, the traceability of process parameters, etc。
Services responsiveness: domesticly produced equipment has natural advantages in terms of delivery cycles, spare parts supply, technical support, etc., and can effectively reduce production operational risks。
Industry users should choose partners with continuous r & d capacity and improved service systems, taking into account their own technology routes, capacity planning and budgetary constraints, to address the process challenges of rapid and iterative industries such as semiconductors and new energy sources。
