  • Proactive BOM Analysis: Turning Supply Chain Risk Into Competitive Advantage

    Proactive BOM Analysis: Turning Supply Chain Risk Into Competitive Advantage
    2026/07/14
    What if the part you approved in five minutes ends up costing your company ten million dollars down the line? What you’ll learn… (00:12) Why the Bill of Materials is quietly one of the biggest risk factors in electronics engineering (02:23) Eric Rimkeit's path from semiconductor procurement to HP commodity management to SupplyFrame (03:15) Ryan Chan's 20 years in supply chain strategy — and how SupplyFrame joined Siemens (04:24) A day in the life of an engineer buried under vintage charts, build checkpoints, and redesign requests (09:06) The real cost curve of a bad part: $1,000 to swap it on paper vs. $10 million once it's in the field (16:24) Why engineering and procurement don't talk — and who ends up "picking up the tab" (20:29) The unauthorized-parts-swap story from an overseas contract manufacturer (22:46) The lead-fishing-weight-and-ivy stunt Eric used to shake a team out of denial (29:43) Real results: 14,000 engineering hours saved a month, and $14 million recovered on tail-end parts (38:20) The three AI shifts reshaping BOM analysis: AI fabric, AI as a design partner, and agentic automation (43:40) The crawl-walk-run approach to actually getting a resiliency program off the ground More about the episode… In this episode of the Printed Circuit Podcast, host Steph Chavez sits down with Eric Rimkeit, Director of Marketing at SupplyFrame, and Ryan Chan, Vice President of Solutions Consulting at SupplyFrame — a Siemens company focused on Bill of Materials risk. Eric spent his career in procurement, from a semiconductor fab through commodity management at HP; Ryan spent two decades guiding companies through supply chain strategy before joining SupplyFrame. The conversation traces what happens when a design gets released without accounting for what's coming downstream: part proliferation, geopolitical disruption, tariffs, and shifting compliance standards that can turn a thousand-dollar swap into a ten-million-dollar redesign. Eric and Ryan unpack why engineering and procurement talk past each other, and share real stories — from an unauthorized parts swap caught on a factory floor to a homemade stunt involving a lead fishing weight and fake ivy — that show what's at stake when teams don't share visibility into risk. They close on where AI is headed next: not replacing engineers, but becoming a design partner that folds supply chain context directly into part selection.

  • Communication, Trust, Process: The Three Pillars Every Co-Design Team Must Get Right

    Communication, Trust, Process: The Three Pillars Every Co-Design Team Must Get Right
    2026/06/30
    What you’ll learn… (00:46) Charlene and Terrie's origin story: a teacher, a career-changer, and 45 years of PCB experience (02:29) What concurrent design actually means — and the "chasing the sun" shift model (04:10) Why communication is the foundation of co-design — and what happens when it breaks down (05:57) The trust factor: building confidence in a teammate's work to hand it straight to the customer (10:06) Where concurrent design goes south in real organizations (11:31) Version control without PLM software: the date-letter-initials convention (15:52) Partitioning a complex motherboard without enterprise software — and who holds the master (21:38) Upfront setup essentials: Gerber outputs, stackup lock-in, and avoiding the rework avalanche (27:40) Treating co-design like a scientist: test revisions and never saying "it won't work" (32:41) The CAM2 success story: world-standard connector, half the typical timeline (37:03) AI in PCB design: a tool for experienced designers — and the lesson from the taping-board era More about the episode… In this episode of the Printed Circuit Podcast, host Steph Chavez sits down with Charlene McCauley, Senior PCB Designer and owner of McCauley Design Group LLC, and Terrie Duffy, Principal Electrical Engineer of AI Automation at Dell Technologies. Charlene brings 45 years of industry experience, including server planer design at Dell and PCB instruction at Austin Community College — where Terrie was her student, worked alongside her for nine years, and now teaches the course herself. The conversation is a practical look at what concurrent and co-design require beyond the tooling: master file ownership, cross-discipline communication, and version control discipline. Real war stories — wrong revisions loaded, external teams deviating from specs — illustrate where co-design breaks down. The CAM2/DDR5 connector project anchors the episode: a world-standard achievement completed in four to five years by a small, tightly coordinated team. The episode closes on AI — not a threat to experienced designers, but a tool that rewards those willing to learn it.

  • The Library Is the Foundation: Why Design Reuse Is Energy Conservation

    The Library Is the Foundation: Why Design Reuse Is Energy Conservation
    2026/06/23
    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.
