It ensures safety, precision, and thermal control, making it an indispensable fixture for technicians handling both iPhone and Android logic board repairs.

Key Features and Benefits

• High-Strength Tempered Glass Platform:
  Built from toughened, heat-resistant glass, the GK21 offers a flat, durable, and stable surface that can withstand the high temperatures of soldering, hot air rework, and BGA reballing operations. It resists deformation, cracking, and surface warping, ensuring long-term durability.

• Superior Heat Insulation:
  The glass structure provides excellent insulation, preventing heat from transferring to your workbench or damaging components. This makes it ideal for long soldering sessions and work with high-powered rework tools.

• Adjustable Aluminum Alloy Clamps:
  The GK21 fixture is equipped with precision-machined adjustable clamps that securely hold mobile phone motherboards, PCBs, and IC chips in place. The adjustable arms accommodate various board sizes, ensuring universal compatibility with iPhone and Android devices.

• Anti-Static Protection:
  The anti-static surface of the tempered glass prevents electrostatic discharge (ESD), protecting sensitive components during high-precision electronic repair.

• Stable and Non-Slip Design:
  Fitted with magnetic suction and silicone anti-slip pads, the GK21 remains securely positioned on the work surface. This guarantees stability and precision even during complex soldering and reballing operations.

• Supports High-Temperature Work:
  The fixture can withstand continuous exposure to heat up to 500°C, making it suitable for hot air gun, soldering iron, and reflow station use.

• Efficient Heat Dissipation:
  The combination of aluminum alloy and tempered glass materials ensures efficient heat dissipation, preventing localized overheating and helping maintain safe working temperatures.

• Easy Maintenance and Cleaning:
  The smooth glass surface makes it easy to clean flux residue, solder, and debris using alcohol or standard PCB cleaning agents — maintaining a professional and clean workspace.
