Chamber 9 inch – 7 bar

The Eurovacuum Helium Bombing chambers are used to inject helium into small, sealed devices in preparation for helium leak testing. The bombing method is commonly used when it is impractical to inject the helium tracer gas into the part during assembly. Generally, bombing is best suited for hermetically sealed devices with small internal cavities and is normally performed with batched parts.

During the bombing process helium flows into the test part through a leak defect. Following bombing, the part is placed in a separate vacuum chamber for helium leak testing. The helium that leaked into the part during bombing will then leak out of the part during leak testing and the part will be classified as a leak.
