Currently Playing: 5 DC Power Integrity Myths That Ruin Your PCB Design

Altium Develop connects your whole team from schematic to fabricated board, so thermal and manufacturability issues in your DC power design get flagged early instead of at the fab: https://www.altium.com/develop?utm_source=youtube&utm_medium=video&utm_campaign=power-integrity&utm_content=5-dc-power-integrity-myths-that-ruin-your-pcb-design DC power integrity quietly shapes the reliability of nearly every power electronics board you'll design, yet it's surrounded by persistent myths that lead to suboptimal decisions. In this video, Zach Peterson breaks down the five most common DC power integrity myths—covering industry standards like IPC 2152 and IPC 2221, the real limits of heavy copper, power layer allocation, via usage, and component placement—so you can size your traces and rails correctly and avoid overheating, hot spots, and current imbalance in your PCB. Using live examples from the Altium blog, real design files, and Gerber data, you'll see exactly why thermal calculators disagree, when heavy copper actually helps versus when it wrecks your manufacturability, how to divide a power plane into multiple rails, and why too many vias turn your copper into "Swiss cheese." Featuring expert insights from Mike Jouppi and Caleb Buck, this is an essential watch for any PCB designer or power electronics engineer who wants to build DC power boards that pass thermal testing the first time. 👉 Resources from this video: - IPC-2221 Calculator for PCB Trace Current and Heating: https://resources.altium.com/p/ipc-2221-calculator-pcb-trace-current-and-heating - Using an IPC-2152 Calculator: Designing to Standards: https://resources.altium.com/p/using-ipc-2152-calculator-designing-standards - Simplify Analysis with Power Analyzer by Keysight: https://www.youtube.com/watch?v=MeHowtR3_As - High Power PCB Design: Pushing the Limits with Caleb Buck: https://youtu.be/aYi080GbV08?si=a_xZbmaRw0y82NMv - Thermal Management in PCB Today: https://youtu.be/A4o2MzFRL_U?si=5467yuzo56pPSrnw 💡 Stay Connected: Don't forget to like, comment, and subscribe for more in-depth tutorials and tips from @AltiumAcademy Share your thoughts and questions in the comments below! 👉 Subscribe for more: https://www.youtube.com/@AltiumAcademy?sub_confirmation=1 Don't forget to follow us on social to stay up-to-date on the latest Altium Academy content. 👉 Follow Altium on TikTok: https://www.tiktok.com/@altiumdesigner 👉 Follow Altium on Twitter: https://twitter.com/altium 👉 Follow Altium on Linkedin: https://www.linkedin.com/company/altium/ 👉 Follow Altium on Facebook: https://www.facebook.com/AltiumOfficial/ The Altium Academy is an online experience created to bring modern education to PCB Designers and Engineers all across the world.
