How Hardware Startups Use Helium Leak Testing for Hermetic Seals
In this episode of Hardware Startups with Fexingo, Lucas and Luna explore how helium leak testing helps hardware startups ensure hermetic seals in devices ranging from medical implants to outdoor sensors. They break down the physics — helium molecules are tiny, so any leak shows up fast — and walk through the setup: a vacuum chamber, a mass spectrometer, and a canister of helium. Lucas explains why the rule of thumb is a leak rate below 1 times 10 to the minus 9 standard cubic centimeters per second for truly sealed enclosures. He shares how a startup making wearable insulin pumps saved…
