CircuitSense™ — Spot Dead Inductors in Seconds Without Lifting a Soldering Iron

Spot a Dead Inductor in Seconds — Without Cracking Open the Board

You've got a phone on the bench with a dead rail. Instead of desoldering coil after coil hunting for the bad one, CircuitSense™ reads the PCB through electromagnetic induction while every component stays where it is. Press the button, watch the LED — a healthy inductor lights green, a dead one stays dark. No removal, no second-guessing, no scorched pads.

Stop Losing an Hour to Every Dead-Rail Diagnosis

You know the drill. A "won't turn on" job hits the bench. The multimeter says nothing useful, the LCR meter needs the coil out of circuit, and now you're warming up the iron for a fault that might be three inductors away. Conventional gear keeps you guessing. CircuitSense™ tells you which coil to focus on before you reach for the desoldering iron.

Why an LED Beats Your LCR Meter on Board-Level Repairs

LCR meters measure inductance values — useful at the bench, unreliable on a live board where parallel components throw the reading. CircuitSense™ skips that problem entirely. Its sensor picks up the high-frequency switching pulses a working inductor emits. If the coil is alive, the pulses are there. If it's open or shorted, they're not.

That's why it nails dead CPU rails, shorted VRMs, and missing gate-drive signals without you touching a single component. You move faster because you're not guessing — you're reading a binary answer straight off the board.

Why Phone Repair Techs Reach for CircuitSense™ First

Most pros start skeptical — induction-based testing sounds too simple to be reliable. Then they run it on the next no-power job and find the dead coil before the soldering iron even warms up. The reaction is consistent: not a replacement for every tool in the kit, but the first one out of the drawer on any power-rail diagnosis.

"Figured it was another gimmick. Ran it on a Galaxy board that wouldn't post and it flagged the dead inductor in under a minute. Saved me an hour of guessing." — Diego R., independent phone repair

Diagnose Faster. Protect Boards. Stop Guessing on Power Rails.

Diagnose a Dead Coil in 3 Quick Steps

Step 1: Power down the board completely and discharge any large caps. CircuitSense™ reads switching pulses, so a powered-off board is the safest, cleanest test.

Step 2: Plug CircuitSense™ into any USB-C source — power bank, phone charger, or your laptop port. Position the probe tip directly over the inductor you want to check.

Step 3: Press the single button. A green light means the coil is alive. No light means you've located the suspect — confirm with a continuity check and move on to the fix.

The Specs Worth Knowing

One Tool. Cleaner Diagnostics. Fewer Boards Ruined Hunting for Dead Coils.

CircuitSense™ pays for itself the first time it spots a dead coil before you wreck the pads digging it out. Add one to the bench kit. If it doesn't earn a permanent spot in the drawer, send it back — we'd rather refund than have it gather dust.
