The 2UUL BH21 Glass OX Jig is a universal fixture used in mobile phone repair, especially during glass or touch (OX) replacement on modern smartphones. It holds the phone’s frame and PCB (printed circuit board) securely in place while you work, allowing repairers to heat, separate, remove, and install components with greater safety and precision.

 

Key Features & Design

 

Universal Compatibility
Designed to fit a wide range of phone models and sizes, making it versatile for many device types.

 

Secure Clamping
Provides firm mechanical support for the phone’s glass panel and the internal PCB, reducing risk of shifting during operations like heating, applying force, or gluing.

 

Material & Build
Typically made from durable metals (aluminum alloy or steel) and rigid materials, to withstand heat, pressure, and repeated use.

 

Precision Adjustment
The jig often includes adjustable arms, sliding parts, and alignment guides so you can position the device accurately.

 

Heat & Glue Compatibility
The design accommodates heating elements (hot plates, infrared lamps) and allows access for adhesive application or removal (OX glue, B‑oxia, etc.)

 

Non‑damage Design
It’s meant to minimize stress or bending on the phone’s housing, glass, or flex cables while being clamped.

 

Stable Base
A sturdy base to prevent slipping or shifting when applying force or during heating cycles.

 

Typical Use Cases

 

Glass / Touch Screen Replacement (OX Repair)
When separating or bonding glass panels (with adhesive) from the frame, the jig holds things securely and allows controlled heating / cooling.

 

PCB Work During Rear Glass Removal
While removing or installing the rear glass or camera module, the PCB is held stable so connectivity or delicate parts aren’t disturbed.

 

Glue / Adhesive Application & Curing
You can use the jig to keep parts in correct alignment while adhesive cures.

 

Multistage Repair Workflow
In professional repair shops, the jig lets technicians move between heating, cleaning, lamination, and reassembly without repositioning the device excessively.
