The Ugly Truth About Prototyping a New Product
Host John Teel explains the iterative stages of prototyping electronic hardware, emphasizing that no single prototype suffices for mass production. He details the progression from low-cost Proof of Concept (POC) prototypes using development kits like Arduino or Raspberry Pi to 'looks-like' models made of clay or 3D printed, and 'works-like' prototypes with custom PCBs. Teel outlines the critical transition to pre-production prototypes optimized for injection molding, followed by Engineering Validation Testing (EVT), Design Validation Testing (DVT) for certifications like FCC and UL, and Production Validation Testing (PVT) for pilot runs.
