IPC-2221
The (Generic Standard on Printed Board Design) is the industry foundation for PCB design, establishing requirements for electrical spacing, material selection, and thermal management. Core Design Pillars
- Select trace widths based on operating current, acceptable temperature rise, copper thickness (oz/ft2), and allowable temperature rise.
- Use IPC-2152 for detailed current-carrying capacity if precise thermal modeling is required.
- Example guideline: For typical 1 oz copper and up to 1 A on an external layer, use ≈10–12 mils; internal layers require wider traces for the same current due to reduced cooling.
