How Hardware Startups Use Thermal Cycling Tests

Hardware Startups with Fexingo: Devices, Robotics, and Manufacturing Tech Companies · Aug 12, 2026 · 7m · transcript

In this episode of Hardware Startups with Fexingo, Lucas and Luna explore how thermal cycling tests help hardware startups find weak points before products hit the field. They walk through a real example: a medical device startup that discovered a solder joint failure after 500 thermal cycles, a problem that would have caused field failures and recalls. The hosts break down the science of thermal cycling—how temperature swings create mechanical stress on PCBs, connectors, and enclosures—and offer practical advice on setting up test profiles, interpreting failures, and knowing when to test…
