How Can an Auto Leak Test Machine Be Integrated with Robots and PLCs?
As manufacturers continue to accelerate digital transformation and move toward Smart Factory environments, leak testing is no longer expected to provide only high accuracy. It must also deliver fast cycle times, complete data traceability, and seamless integration with automated production lines. As a result, today’s Auto Leak Test Machine is no longer a standalone inspection […]
Cooling Gas and Vacuum Heat Treatment Quality
In vacuum heat treatment technology, heating a material to the required temperature is only the first step. The final quality of the product largely depends on the cooling stage. Instead of using quenching oil as in conventional systems, modern vacuum furnaces utilize Cooling Gas (high-pressure cooling gas) to reduce the temperature of the workpiece quickly, […]
90% of Factories Overlook This Issue — Leading to Early Failure of Vacuum Furnace Transformers
In many manufacturing facilities across Vietnam, vacuum furnaces are critical assets that directly impact product quality and production efficiency. However, in reality, most major failures such as vacuum furnace transformer burnout, motor damage, and unexpected downtime are not caused by mechanical issues, but by poor power quality. The combination of unstable grid power and high-power […]
COOLING WATER IN VACUUM FURNACES: A CRITICAL SYSTEM FOR EQUIPMENT PROTECTION
In industrial vacuum furnace systems, processing temperatures can range from 800°C to over 2,000°C depending on the application, including heat treatment, sintering, vacuum brazing, carburizing, and advanced materials processing. While the heating zone must operate at extremely high temperatures, the furnace shell, door assembly, vacuum system, and supporting components must be maintained within safe operating […]
Real-World Review of ULVAC Vacuum Furnace After 6 Years of Operation in Vietnam
In the heat treatment and material processing industry, long-term equipment stability is one of the most important factors for manufacturers. A system that performs well immediately after installation is not enough to prove its quality. More importantly, a vacuum heat treatment furnace must maintain its performance, vacuum level, and thermal stability after many years of […]
How to Detect Ultra-Small Gas Leaks (< 10⁻⁹ mbar·L/s) in Semiconductor Vacuum Chambers
In the semiconductor industry, especially in Front-End processes such as Dry Etching, thin film deposition (CVD/ALD), and Ion Implantation, an Ultra-High Vacuum (UHV) environment is absolutely critical. Even a nano-scale gas leak smaller than 10⁻⁹ mbar·L/s can damage an entire wafer worth hundreds of thousands of dollars. In other words, this is an extremely tiny […]
Front-End Semiconductor Manufacturing Process: Where the Magic of Technology Begins
In today’s modern technology world, we constantly hear about powerful semiconductor chips. These chips power supercomputers, smartphones, AI systems, and even autonomous vehicles. However, before a chip becomes fully functional, the silicon wafer must undergo an extremely complex manufacturing journey. This journey is known as the Front-End Process (Wafer Fabrication). This stage is considered the […]
