Board-Level Bench

Device-agnostic micro-soldering workflows: shorts, rework, reballing and schematic reading.

Repairability

9/ 10

high risk

58% of cases

Symptom: Bench supply hits current limit instantly; a component heats within seconds.
Diagnosis: Diode-mode the rails, then use freeze spray or a thermal camera to localise the short.
Solution: Remove the shorted component, verify the rail, and replace it with a matched part.

high risk

92% of cases

Symptom: No fan spin, no charge LED, board draws 0 A on the USB-C meter.
Diagnosis: Follow the power rails in order: input protection, PPBUS, then SMC handshake. A dead short on PPBUS usually points to a failed load switch.
Solution: Repair the failing rail or replace the shorted component; verify a clean 20 V input first.
