JCID M3750A Continuous Zoom Microscope

For most phone board work, 7X to about 50X covers everything from locating a part to checking a single joint. The JCID M3750A is a continuous zoom stereo microscope in that range, built for chip-level repair.

The listing describes a 7–50X zoom, a dust-proof optical system, ergonomic eyepieces with light-leak masks, a metal focus knob, a 144-LED ring light and a heavy base with a heat-resistant silicone pad. It supports external lenses and cameras.

When the M3750A helps

• Cracked joints and broken traces too small to see by eye.

• Damaged FPC connectors needing close work.

• Lifted pads after chip removal.

• Shorted parts on crowded boards.

Binocular or trinocular?

The listing describes the 7050 series as binocular or trinocular, but doesn't say which head this M3750A has. If you want to add a camera later, confirm the trinocular port before ordering.

A camera or external screen isn't included. The box measures 42 × 33 × 25 cm. Fit an auxiliary lens if you need more room under the objective for hot air.
