FOF Bonding Machine

FOF Bonding Machine

Advanced FOF Bonding Machine: Precision Equipment for Flexible Display Manufacturing.

In the rapidly evolving world of touch panel technology, the demand for lightweight, thin, and cost-effective solutions has led to the widespread adoption of Film on Film (FOF) or FPC on FPC, or FPC on Film structures. To meet the stringent requirements of modern production lines, Shenzhen Olian Automatic Equipment Co., Ltd. presents its state-of-the-art Automatic FOF Bonding Machine.

This equipment is specifically engineered to handle the delicate process of bonding Flexible Printed Circuits (FPC) onto PET films, providing a robust solution for mass-producing film-structured touch screens.

🛠️ What is an FOF Bonding Machine?

An FOF (Film on Film),(FPC on FPC), or (FPC on Film) Bonding Machine is a specialized piece of automation equipment used in the touch screen manufacturing process. Unlike traditional glass-based bonding (such as FOG – Film on Glass), FOF technology involves bonding conductive layers and circuits entirely on flexible plastic films (PET).

Our machines are designed to overcome the unique challenges of handling flexible materials, which are prone to warping, curling, and static adhesion. The process typically involves three critical stages:

1. ACF Attachment: Precisely applying Anisotropic Conductive Film to the designated area.
2. Pre-Bonding: Aligning and temporarily pressing the FPC onto the film.
3. Main Bonding (Thermal Pressing): Applying heat, pressure, and time to create a permanent, electrically conductive connection.

🔍 Core Technological Advantages

Drawing from our extensive experience in LCD module (LCM) and touch panel equipment, our FOF Bonding Machines incorporate several key technological breakthroughs:

1. Specialized ACF Application System

Bonding film-to-film presents a unique challenge because the ITO pins on double-layer films are often recessed. Standard flat pressure can lead to uneven adhesion.

• Solution: We utilize a specialized “Convex Silicone Belt” embedded within a concave pressure head.
• Benefit: This design provides a large buffering capacity, ensuring uniform pressure even on uneven surfaces. It prevents “pulling glue” during peeling and allows for quick changeovers by simply replacing the belt, not the entire head.

2. High-Precision Visual Alignment

Precision is paramount in display manufacturing. Our machines feature advanced machine vision systems that scan fiducial marks on both the FPC and the film.

• Accuracy: Achieving a bonding accuracy of ±15μm.1）ACF attaching accuracy：X: ±0.2mm , Y±0.15mm
• 2）FPC pre-bonding accuracy：X: ±7um , Y±7um
• 3）FPC final-bonding accuracy：X: ±15um , Y±15um
• Function: The system automatically corrects positional, ensuring perfect alignment of microscopic circuits.

3. Stable Thermal Pressing Mechanism

Heat is the catalyst for the ACF to cure and form a conductive bridge.

• Temperature Control: Utilizing high-precision temperature control systems to maintain stability within the range of 0°C to 399°C.
• Pressure Control: Equipped with imported pneumatic components (such as those from SMC or Festo) to ensure stable pressure application between 0.01 to 0.2MPa.
