Mobile phone repair shops, wholesalers, training centers, and refurbishment companies increasingly rely on advanced OCA (Optically Clear Adhesive) machines to deliver spotless screen repairs. This guide introduces the TBK-708, a compact 2-in-1 OCA vacuum laminating machine that integrates lamination and bubble removal into a seamless operation. Building from beginner basics through calibration, troubleshooting, lamination processes, and maintenance, this comprehensive resource equips professionals to maximize efficiency and repair quality.
The TBK-708 combines vacuum lamination and de-foaming functions in a single, intelligent unit designed for professional mobile device screen repairs. Highlights include:
Intelligent airbag system applying even pressure on curved, straight, and flat screens without molds
One-touch start and user-friendly touchscreen for precise control of temperature, pressure, and timing
Spacious 15-inch working area accommodating phones, tablets, and watches
Compact design suited for repair shops, wholesalers, and training environments
This machine solves common OCA repair challenges, reducing bubbles and enhancing screen clarity with minimal operator effort.
For mobile repair novices, operating an OCA machine for the first time can be intimidating. The TBK-708’s intuitive touchscreen simplifies onboarding.
Steps for first-time use:
Preparation: Clean the screen and OCA film thoroughly to avoid dust and contaminants.
Power on: Press the one-touch start button to activate the machine.
Settings: Use the touchscreen to select preset programs or manually adjust temperature and pressure based on device type.
Placement: Position the screen and OCA film on the working platform beneath the intelligent airbag.
Start lamination: Initiate vacuum lamination. The airbag evenly distributes pressure to ensure perfect adhesion without bubbles.
De-foaming: The built-in bubble remover operates simultaneously to expel trapped air.
Completion: After process completion, carefully remove the laminated screen.
The machine’s design eliminates mold requirements, supporting curved and flat screens effortlessly—ideal for diverse repair needs. Beginners benefit from preset programs that simplify calibration.
Precise calibration is critical to achieve bubble-free adhesion and device compatibility. The TBK-708 allows fine-tuning of pressure and temperature, which vary by screen type and size.
Key calibration considerations:
Pressure calibration: Ensure the airbag applies enough force evenly. Excessive pressure can damage screens, while insufficient pressure results in bubbles or weak adhesion.
Temperature settings: OCA film activation varies by type; LCD and OLED screens may require different temperature profiles.
Vacuum intensity: Stronger vacuum prevents air pockets but must be adjusted per device specifications.
Calibration helps adapt the machine to a wide device range, improving first-pass yield. The TBK-708’s touchscreen interface facilitates easy calibration saves, speeding setup.
Operators may encounter issues such as bubbles, incomplete adhesion, or vacuum failures. Common causes and solutions include:
| Problem | Cause | Solution |
|---|---|---|
| Persistent bubbles | Improper pressure or dust contamination | Recalibrate pressure, clean screen and film |
| Film not sticking | Incorrect temperature or dirty surfaces | Adjust temperature, clean surfaces thoroughly |
| Vacuum pump failures | Blockages or leaks | Inspect vacuum lines for leaks or obstructions |
| Uneven lamination | Faulty airbag system or misalignment | Check airbag integrity and ensure proper placement |
The TBK-708’s diagnostic alerts and user-friendly UI simplify identifying and resolving issues efficiently.
The lamination stage merges the OCA film with the mobile screen using vacuum and pressure technology to ensure transparency and durability.
Process steps:
Cleaning: Meticulous cleaning of components and workspace to prevent dust.
Alignment: Accurate positioning of OCA film to the screen.
Vacuum lamination: Removing air bubbles via vacuum suction.
Pressurization: Even force application through the airbag.
De-foaming: Removal of remaining micro-bubbles for a flawless finish.
The TBK-708’s integrated bubble remover and large working area streamline this multi-step repair with minimal manual intervention.
Routine care ensures sustained performance and reduces downtime.
Maintenance tips:
Regularly clean the working surface and airbag with appropriate solvents.
Check vacuum pump oil levels and replace oil as needed.
Inspect vacuum seals and hoses for wear or cracks.
Calibrate sensors periodically to maintain accuracy.
Following these best practices extends the TBK-708’s operational life and maximizes repair quality consistency.
