About this episode

What you’ll learn…

  • (00:12) Why design reuse is energy conservation — and IP management is energy management

  • (05:15) How the shift from physical tape-ups to CAD opened the door to reusable design data

  • (08:09) The electric car analogy: charging cheap vs. designing under pressure

  • (11:32) War stories from the field: reverse-engineering an F-14 Tomcat board and the square-pin-in-a-round-hole disaster

  • (17:07) What happens when every designer controls their own library — and why that's a nightmare

  • (21:33) Family trees, variants, and the art of tracking design history across decades

  • (25:47) Why even great processes break down — and the role of the resident expert in keeping libraries honest

  • (30:26) The designer as cross-pollinator: bridging mechanical, electrical, and manufacturing worlds

  • (38:19) AI as a routing engine: from overnight Cadnetics autorouting to Tesla autopilot — and what both teach us about human oversight

More about the episode…

In this episode of the Printed Circuit Podcast, host Steph Chavez welcomes Paul Fleming, Senior Printed Circuit Board Consultant and IPC-certified design instructor — a 45-year industry veteran who built his own PCB service bureau in San Diego before spending two decades as an application engineer across Cadnetics, Cadence, Mentor Graphics, and Siemens, and becoming an educator through the IPC Designer Council.

The conversation tackles why design reuse and IP management are the hidden levers behind every fast, cost-efficient hardware program — and why neglecting them is a tax companies keep paying long after the original engineer has left. Paul frames it simply: decisions are energy, and every design artifact is either stored potential or future debt. War stories from a reverse-engineered F-14 Tomcat board to a connector library defect that cascaded across hundreds of shipped units make the stakes concrete.

Paul also addresses the human side: the self-preservation instinct that fragments shared libraries, the management–engineering gap that lets bad habits compound, and why the PCB designer — bridging mechanical, electrical, and manufacturing domains — holds more organizational leverage than almost any other role on the product team. The episode closes with a candid take on AI: powerful when an experienced engineer is watching the road, dangerous when they're not.
