Caractéristiques et spécifications du dispositif de réparation de téléphone à double roulement Ansiki Mijing K22Pro

The double bearing rotation system uses two independent precision bearings to support the rotating arm, eliminating the lateral play that causes single-bearing fixtures to shift mid-solder and damage delicate pads. Stable phone motherboard clamping is achieved through a knurled locking screw that applies even pressure across the PCB edge without flexing thin boards, a critical detail when working on modern 0.4 mm-thick smartphone logic boards. The jaw opening adjusts from 10 mm to 120 mm, covering everything from compact phone motherboards to larger tablet PCBs and multi-layer repair panels. IC chip soldering support is built into the platform geometry — the angled work surface lets hot air flow freely beneath the board, preventing heat soak into adjacent components during BGA and QFN rework. Black glue removal becomes significantly safer with this fixture because you hold the board steady with both hands on your tools rather than one hand gripping the PCB, reducing the risk of slipping and scratching surrounding components.
