*Michito Hirayama¹ (1. Measurement Instruments Department Components Business HQ, ULVAC, Inc.)

Helium leak testing is used in a variety of industries, including vacuum equipment and components, automotive, air conditioning and refrigeration, electronic devices and components, food, medical, energy, and general industry. Helium leak detectors have been developed for these various applications. In recent years, the automotive industry has seen an increase in the number of products requiring helium leak testing due to the major shift to next generation vehicles such as electric and fuel cell vehicles. In particular, helium leak testing is increasingly being used for rechargeable batteries leak testing. In this presentation, I will describe the latest trends in helium leak testing and helium leak test systems used in production lines such as rechargeable batteries, and report on the performance and features required of helium leak detectors.
