Relays for Third Generation Semiconductor Testing Equipment

With the development of 5G, new energy vehicles, charging stations, photovoltaics, and rail transit, the demand for semiconductor devices is growing, and the requirements for their reliability and performance are becoming increasingly stringent. Thus, the third-generation semiconductor market has emerged.

Third-generation semiconductors such as silicon carbide (SiC) and gallium nitride (GaN) require high voltage and large current testing, which demands relays with high switching voltage and withstand voltage and high current pulse endurance. Micronale Electronics provides a series of relays using internationally matured mercury and dry reed technologies, which, through rigorous internal screening tests, can meet the requirements of third-generation semiconductor testing equipment:

  • High insulation resistance High insulation has always been the pursuit of semiconductor testing equipment. Leakage current between high and low voltages must be less than 0.1nA under 1000V voltage, which requires the relay’s insulation resistance to be above 10T ohms. Micronale Electronics’ HGFR series mercury relays and HVFG series dry reed relays use special processes to ensure that the insulation resistance between contacts, between contacts and coils, fully meets customer needs.
  • High withstand voltage As the first choice for testing third-generation semiconductor devices, Micronale relays have high insulation and withstand voltage characteristics, with the highest withstand voltage of the dry reed relay reaching 20KV and that of the mercury dry reed relay exceeding 10KV.
  • Long switching life Semiconductor packaging testing factories operate 24 hours a day, and have high requirements for the switching efficiency of relays. Micronale’s dry reed relays have a switching time of less than 1.2ms, and can achieve several hundred switching times per second, easily meeting customers’ efficiency requirements. At the same time, the contact coating uses rare metal ruthenium materials to ensure the stability of contact resistance after billions of switching times, meeting the requirements of high switching life.
