The MiJing AP-11 Earphone Repair Fixture is a multi-model clamping and maintenance station engineered specifically for wireless earbud repair labs and audio refurbishing technicians. Compatible with Apple AirPods 1st, 2nd, and 3rd Generation, as well as AirPods Pro 1 and AirPods Pro 2, this fixture solves the challenge of repairing delicate acoustic hardware: opening tightly sealed earphone shells, swapping degraded button-cell batteries, and replacing flex cables without deforming or cracking the glossy plastic housing.
Manufactured with high-density synthetic stone and CNC-machined aluminum alloy, the AP-11 features custom 1:1 contoured bays tailored to the ergonomic curvature of each earbud model. By distributing mechanical pressure across the earphone body, it prevents pressure dents and cosmetic scratching while giving technicians steady access during micro-soldering, adhesive scraping, and alignment for ultrasonic or glue resealing.
Key Engineering Features & Bench Advantages:
- Multi-Generation 5-in-1 Earbud Compatibility: Features precision-milled modular slots configured for AirPods 1, AirPods 2, AirPods 3, AirPods Pro 1, and AirPods Pro 2 housings.
- 360° Rotational & Multi-Angle Positioning: Allows smooth rotational adjustment and locking so technicians can orient the earbud at an optimal angle under microscope optics for delicate pad tinning and wire jumping.
- Traceless Clamping Architecture: Contoured composite holding bays prevent gouging, scuffing, or crushing fragile white polycarbonate shells during high-pressure opening procedures.
- High-Temperature Synthetic Stone Construction: Built with heat-insulating synthetic stone (Bakelite/composite stone) that withstands direct hot air rework temperatures without warping or transferring heat to adjacent plastics.
- Steady Precision Screw Clamping: Integrated knurled thumbscrew knob delivers micrometric tension adjustment, securing the earbud firmly to prevent slippage during blade insertion or rotary tool edge milling.
- Non-Slip Weighted Base: Solid, counterweighted bench footprint with anti-static silicone foot pads keeps the fixture anchored on your silicone bench mat during high-leverage operations.

Bench Workflow & Repair Guide:
- Model Bay Selection: Identify the correct contoured groove on the MiJing AP-11 corresponding to your specific earbud (standard stem vs. Pro in-ear profile).
- Secure Earbud: Seat the earphone into the silicone/synthetic stone slot and rotate the precision side thumbscrew until the earbud is gripped firmly without over-tightening.
- Adhesive Softening: Apply targeted hot air (around 100°C–120°C with a concentrated nozzle) or a softening solvent along the ultrasonic seam line while the shell remains secured in the fixture.
- Shell Separation & Battery Desoldering: Insert an ultra-thin pry blade to crack the softened glue perimeter, lift the battery or sensor bracket, and micro-solder the new replacement battery cell leads under your microscope.
- Reassembly & Curing Clamp: Apply specialized structural earphone sealant (such as B-7000 or black acoustic adhesive), re-seat the shell, and use the fixture's uniform pressure clamp to hold the halves aligned while the adhesive cures.
