How NLCRC expects short-finding to be done safely (paraphrased from widely taught bench rules; original text).
Rules of thumb
- Know the rail and a safe current budget before injecting.
- Start low; watch for heating components; do not cook a multilayer short blindly.
- Prefer resistance mapping and BoardView net lists before high current.
Never
- Inject into a lithium pack path.
- Leave injection unattended.
- Assume “the hottest chip is always the fault” — copper pours lie.
Document amps used, rail name, and what warmed up when you report success (or failure).
