Episode 122 of The Hardware Podcast dives into a microscopic engineering innovation that's quietly reshaping semiconductor packaging: on-chip microsprings. Lucas and Luna explore how these tiny compliant structures—essentially microscopic coiled wires—are replacing traditional solder bumps in chiplet-based designs. They discuss the reliability challenges of heterogeneous integration, why companies like Tesla and AMD are moving toward chiplets, and how microsprings solve the thermal mismatch problem that kills conventional interconnects. The conversation zeroes in on a specific case: the transition from microbumps to microsprings at a leading packaging foundry, citing a 10x improvement in reliability under thermal cycling. Lucas explains the fabrication process using photolithography and electroplating, while Luna asks sharp questions about yield and cost. The episode closes with a forward look at how microsprings could enable modular chip design for AI accelerators. A fresh angle on chip interconnect technology that hasn't been covered in prior episodes. #Microsprings #ChipletInterconnects #SemiconductorPackaging #HeterogeneousIntegration #AdvancedPackaging #ChipDesign #Microbumps #ThermalCycling #Reliability #AIAccelerators #Tesla #AMD #Photolithography #Electroplating #ModularChips #Engineering #Technology #FexingoBusiness Keep every episode free: buymeacoffee.com/fexingo
