Lucas and Luna unpack Design for Test (DFT) — the engineering discipline that builds testability into hardware before the first prototype is made. They walk through a concrete case: a medical-device startup that embedded JTAG test points, boundary-scan cells, and test-access ports into its PCB layout from revision zero. The result? They caught 94 percent of soldering defects during first-article inspection, not in the field. Lucas explains how DFT cuts debug time from weeks to hours, slashes re-spin costs, and why skipping it is the single most expensive shortcut a hardware startup can take. Luna pushes back on the added board space and upfront engineering hours — and Lucas shows how the math flips by production run 500. They also touch on the open-source boundary-scan tool OpenOCD and why venture-backed founders who ignore DFT are burning their own cap table. A focused episode for anyone building physical products who wants to ship faster without the field-failure nightmare. #DesignForTest #DFT #HardwareStartups #HardwareEngineering #PCBLayout #BoundaryScan #JTAG #TestAccessPort #OpenOCD #MedicalDevice #Manufacturing #YieldImprovement #DefectDetection #FirstArticleInspection #ProductDevelopment #Business #Technology #FexingoBusiness Keep every episode free: buymeacoffee.com/fexingo
