Episode 54 of Hardware Startups with Fexingo dives into thermal interface materials (TIMs) — the unsung heroes of heat management in compact devices. Lucas and Luna explore why TIMs matter more than ever as hardware shrinks and power densities climb. They break down the differences between thermal pastes, gap pads, and phase-change materials, using real-world examples like a drone startup that avoided field failures by switching from a cheap thermal pad to a high-performance thermal grease. The hosts explain key metrics like thermal conductivity and thermal impedance, and discuss how to select the right TIM for cost-sensitive production runs. They also touch on application methods — from screen printing to automated dispensing — and warn about common pitfalls like pump-out and dry-out. By the end, listeners will know how to evaluate TIMs for their own hardware projects without over-engineering. A must-hear for anyone designing electronics that generate heat.
