FOG Production Process: A Comprehensive Guide by DINGTouch

In the ever-evolving world of touch screen technology, DINGTouch stands out as a leader in providing cutting-edge solutions for various industries. One of the critical processes in our touch screen manufacturing is the FOG (FPC on Glass) production process, a technique that ensures the seamless integration of flexible printed circuits (FPC) with LCD glass. This article delves into the FOG process, highlighting its significance, the meticulous steps involved, and the stringent quality control measures that set DINGTouch apart from competitors.

What is the FOG Production Process?

The FOG (FPC on Glass) production process is a sophisticated technique that involves the mechanical and electrical bonding of liquid crystal display (LCD) glass with flexible printed circuits (FPC) using Anisotropic Conductive Film (ACF). This process is crucial in ensuring the functionality and reliability of touch screens used in various applications, from industrial controls to smart home devices.

Step-by-Step Breakdown of the FOG Process

At DINGTouch, the FOG production process is carried out with precision and care, adhering to the highest industry standards. The process involves the following key steps:

1. ACF Pre-Attachment
   The process begins with the pre-attachment of ACF to the LCD glass or FPC. Using precise temperature and pressure settings, the ACF is applied to the specific areas where the bonding will occur. The accuracy of this step is crucial, as it ensures that the ACF is applied with the correct length and position, maintaining a flat surface free of bubbles.

2. Pre-Bonding
   Next, the FPC and LCD are aligned using advanced image processing systems. This alignment must be incredibly precise, as the pitch between the lines is often as small as 0.05 mm, requiring alignment accuracy within ±0.005 mm. Once aligned, the pre-bonding process creates an initial connection between the FPC and LCD.

3. Main Bonding
   The main bonding step involves subjecting the pre-bonded assembly to higher temperatures and pressures. This causes the conductive particles in the ACF to deform and break through the insulation layer, creating a reliable electrical connection between the FPC and LCD glass. Simultaneously, the ACF adhesive hardens, providing mechanical strength to the bond.

4. Quality Inspection
   The final step in the FOG process is a thorough inspection of the bonded product. At DINGTouch, we utilize electron microscopes with magnification up to 500 times to inspect the bonds, ensuring that each product meets our stringent quality standards.

Key Technologies in FOG Production

Ensuring the highest quality in FOG production requires advanced technology and meticulous attention to detail. At DINGTouch, we focus on three critical aspects:

1. Pressure Control
   The bonding pressure directly influences the quality of the connection between the FPC and LCD. Too much pressure can crush the conductive particles in the ACF, leading to electrical failure, while too little pressure may result in an inadequate bond. DINGTouch’s state-of-the-art equipment allows for precise pressure control, ensuring optimal results.

2. Temperature Management
   The curing of the ACF adhesive depends on the rate of temperature increase and the peak temperature achieved. At DINGTouch, we carefully control these parameters to ensure that the bond is strong and the surface quality is maintained, avoiding defects such as bubbles or pinholes.

3. Flatness of the Bonding Head
   The flatness of the bonding head is crucial in the FOG process. An uneven bonding head can cause uneven pressure distribution, leading to issues such as incomplete bonding or the formation of bubbles within the ACF. DINGTouch’s equipment undergoes regular calibration and maintenance to ensure the flatness and alignment of the bonding head, preventing these issues and ensuring high-quality bonds.
