Drone PDB Trace Width Calculator
25 A-per-ESC copper on a 40 mm board — burst-duty sizing, battery-pad reinforcement and the input-capacitor rule.
Preset for this niche — adjust to your stack-up. IPC-2221 assumes still air; verify hot paths with a thermal camera.
Drone PDB Trace Width Calculator computes power-distribution copper for multirotors where burst duty and prop wash change the rules — free, instant and private in your browser. FPV builders making or reviewing PDBs and 4-in-1 ESC layouts use it to skip the datasheet algebra: type your numbers, read the answer with the substituted formula shown step by step, and share an exact permalink of the calculation.
About Drone PDB Trace Width Calculator
Drone PDB Trace Width Calculator computes power-distribution copper for multirotors where burst duty and prop wash change the rules using the standard engineering relation: IPC-2221 with quad presets: 25 A/ESC, 30 °C transient rise, 2 oz multi-layer copper. Worked live: a 5-inch quad's 100 A punch-out rides on paralleled 2–3 oz layers a few millimetres long — duty cycle is the saviour. The result recalculates on every keystroke, the worked-example panel shows your numbers substituted into the formula, and the Copy permalink button encodes the inputs in the URL so a colleague opens exactly your calculation. Everything runs client-side — nothing you type leaves your device.

Frequently asked questions
How do you calculate drone pdb trace width?+
Power-distribution copper for multirotors where burst duty and prop wash change the rules follows IPC-2221 with quad presets: 25 A/ESC, 30 °C transient rise, 2 oz multi-layer copper. For example, a 5-inch quad's 100 A punch-out rides on paralleled 2–3 oz layers a few millimetres long — duty cycle is the saviour. The calculator applies the same relation and shows the substituted arithmetic so you can verify every step.
Why do drone boards survive currents that would melt normal PCBs?+
Three discounts: bursts of seconds ride on copper thermal mass (hover current is 4–5× lower), every layer of a 4–6 layer stack carries current in parallel, and propeller wash is forced-air cooling most electronics never get. Ground-vehicle or fixed-mount builds lose discount #3 — derate accordingly.
What kills PDBs and 4-in-1s in practice?+
Battery-lead pads: a heavy pigtail vibrating on a cold-soldered pad cracks it; the resistance rises and the pad chars. Pre-tin, use an 80 W+ iron for fast wetting, strain-relieve the pigtail to the frame, and add the low-ESR capacitor — it tames the spikes that finish weakened FETs.
Is the Drone PDB Trace Width Calculator free and private?+
Yes — completely free with no sign-up or usage limits, and it runs entirely in your browser: the values you enter are never uploaded or stored on a server.
