description: "Discussion on \"When a PCB Carries 1,000 Amps: The Thermodynamics, Materials Science, and Manufacturing Limits You Must Face\". Based on AnyPCBA's small-to-medium volume PCB and PCBA manufacturing experience, this guide explains the thermodynamics, materials science, and manufacturing limits of high-current PCBs—from heavy copper and thermal vias to IPC-2152 trace width and etching undercut—and how DFM review prevents catastrophic failure before production."
