How to fix iPhone x Screen without Air Bubble 2025

The Process of Laminating OCA iPhone x Front Glass with OLED

iPhone x laminating the OCA (Optically Clear Adhesive) front glass with an OLED display is a precise and delicate process that requires careful control over pressure, temperature, and air removal. If the power is unevenly distributed, the temperature is too high or too low, or if air fails to escape properly, bubbles will form. While most bubbles can be eliminated after deforming, stubborn bubbles require a second separation and re-lamination.

Key Points for Reducing Air Bubbles

Drawing from principles and practical application experience, Reformtech has identified key factors in minimizing air bubbles and avoiding persistent bubbles. These include:

• Correct Operation Techniques: Following precise procedures ensures minimal air entrapment.
• Suitable Tools and Supplies: Using high-quality tools contributes to a seamless lamination process.
• Accurate Machine Parameter Settings: Adjusting pressure, temperature, and time settings optimally prevents defects.

Step-by-Step Demonstration of the Laminating Process

Step 1: Front Glass Separation

Front glass separation can be categorized into:

1. Bracket-Preserving Separation: This method retains the original bracket, providing a better fit. However, it demands advanced skills and is recommended only if the bracket is in good condition without breaks.
2. Non-Bracket-Preserving Separation: This method is easier, especially for beginners, as it simplifies locating the gap between the front glass and OLED.

Procedure:

• Use cutting wire to create an entry point at the bottom corner of the screen.
• Separate the OLED along the bottom layer of the glass using cutting wire.

Step 2: Cleaning the OCA Adhesive

Thorough OCA adhesive removal is essential for successful lamination. The commonly used tools include:

• Electric OCA Glue Remover: Offers wider adaptability, moderate difficulty, and time-sensitive application.
• OCA Glue Remover Spray: Suitable for iPhone X and later models, dissolves OCA easily without damaging the phone, and is relatively easy to use.
• OCA Glue Remover Sheets: Used for cleaning glass residues after OLED separation; however, it is relatively difficult to operate.

After cleaning the OCA glue, the OLED’s functionality should be tested to ensure normal operation before proceeding.

Step 3: OLED Alignment and Preparation

Since the OLED is often in a bent state, it should be gently straightened before placing it into the alignment mold. High-precision molds ensure proper positioning and improved accuracy.

Steps:

1. Check the alignment to confirm it is flat, not warped, and does not slide.
2. Use a Mitsubishi OCA front glass.
3. When tearing the film, use a sticker instead of tweezers to prevent OCA deformation or air bubble formation.
4. Clean the OLED again.
5. Place the OCA front glass horizontally into the alignment mold, which has spring tabs to maintain horizontal positioning.
6. Tap the center of the front glass to allow partial attachment of OCA to the OLED. The middle of the front cover and OLED must bond first to ensure the OLED does not shift when inverted.

Step 4: Laminating the OLED and OCA Front Glass

1. Invert the mold flatly and remove the OLED.
2. Use two 6mm rubber mats to place the screen into the FM30 laminating machine.
3. Set the machine parameters accurately to ensure even pressure and temperature distribution.
4. Complete the lamination process.

Step 5: Testing and Final Assembly

1. Reinstall the laminated screen into the phone.
2. Test the display and touch functions to ensure proper operation.
3. If display and touch functions are perfect, apply OEM glue evenly around the bracket.
4. Align and secure the laminated OLED in place.

Conclusion

Following these steps meticulously ensures a high success rate in OCA front glass and OLED lamination. Proper equipment, correct operation techniques, and precise machine settings help reduce air bubbles, leading to a flawless final product. Adhering to these guidelines will enhance efficiency and quality in iPhone x screen repairs.
