The Spark Gap - Episode 20

The Spark Gap · 29 Oct 2014 · 30m

What this episode covers

Hosts Carl and Corey discuss lessons learned from discarding old PCBs, focusing on GPIO expanders, interconnect design, and power protection. They argue against using GPIO expanders due to weak drive strengths and timing gotchas, recommending larger microcontrollers instead. They detail the risks of non-symmetric daughter card connectors and the necessity of robust input power protection to prevent damage from incorrect adapters.

    High Power PCB Design: Pushing the Limits with Caleb Buck

    Caleb Buck, a PCB Design Electronics Engineer at Nidec Aerospace, discusses the complexities of high-power PCB design, ranging from guitar pedal prototypes to aerospace systems handling over 500 amps. He explains how uneven current distribution in parallel switching circuits can cause connectors to melt due to impedance mismatches, emphasizing the need for symmetrical layout. Buck also details the importance of voltage isolation standards like IPC 2221 Revision C and IPC 2152, material selection for thermal reliability, and the pitfalls of conformal coating on high-power components.
