SUNSHINE TB-03S Mini Infrared Rapid Thermal Camera

Space under a microscope is tight, and a bulky camera gets in the way of probes and tweezers. The SUNSHINE TB-03S Mini is a compact thermal camera for spotting the hot part on a shorted board without crowding the bench.

The listing describes rapid infrared imaging that shows temperature differences across the board, sized for small ICs, capacitors and resistors, with simple operation. It gives no resolution, temperature range, screen size, battery details or package contents.

Faults it helps find

• A shorted capacitor on the main rail.

• Abnormal drain on a dead phone.

• A failing power IC that runs hot.

• Leakage after water damage.

Method

Inject a low, current-limited voltage into the shorted line and watch for the first part to warm. Check the board cold first so you know the baseline, and confirm the find with a meter before lifting the part.

If you want a bigger view, the TB-08 Ultra has a 4-inch screen. Ask for the resolution of either before choosing, since a low-resolution sensor can blur two neighboring parts into one warm spot.
