the differences between the COG (Chip On Glass), COF (Chip On Film), and COP (Chip On Plastic) bonding processes:
1. Mounting Location and Substrate
COG : In the COG process, the driver IC is directly mounted onto the glass substrate of the display module. The chip is bonded to the glass surface and connected to the display pixels through fine wires or conductive paths .
COF : In the COF process, the driver IC is mounted onto a flexible printed circuit (FPC) or a thin film substrate. The FPC with the driver IC is then attached to the display module, usually by folding it over the edge of the glass substrate .
COP : In the COP process, the driver IC is directly fixed onto a flexible plastic substrate. This allows the screen to be bent or folded, enabling a more compact and flexible design .
2. Flexibility and Design
COG : The COG process is more rigid due to the direct mounting of the driver IC on the glass substrate. This limits the flexibility of the display module and makes it more difficult to achieve a slim and lightweight design .
COF : The COF process offers greater flexibility and design freedom. The use of a flexible FPC or thin film substrate allows the display module to be bent or folded, making it suitable for applications that require a more compact and flexible design .
COP : The COP process provides the highest level of flexibility and design freedom. The flexible plastic substrate can be bent or folded to a greater extent, enabling the realization of truly borderless or flexible displays .
3. Impact on Screen Size and Bezel
COG : The COG process may result in a slightly smaller screen size compared to COF and COP. The driver IC occupies a certain amount of space on the glass substrate, which can reduce the available area for the display pixels. Additionally, the rigid nature of the COG process may require a wider bezel around the display .
COF : The COF process can provide a larger screen size and a narrower bezel. By mounting the driver IC on a flexible substrate and folding it over the edge of the glass, the chip does not occupy space on the display window, allowing for a larger usable viewing area .
COP : The COP process can further compress the screen module and achieve an almost bezel – less design. The flexible plastic substrate can be folded back directly, further reducing the space occupied by the driver IC and enabling a more seamless and edge – to – edge display .
4. Cost and Yield
COG : The COG process is a more mature and cost – effective technology. It has a relatively high production yield and lower manufacturing costs, making it a popular choice for many display manufacturers .
COF : The COF process is generally more expensive and has a lower production yield compared to COG. This is due to the more complex bonding process and the need for specialized equipment and materials to handle the flexible substrates .
COP : The COP process has the highest cost and the lowest yield among the three. The high degree of flexibility and the need for precise folding and bonding of the flexible plastic substrate make it a more challenging and costly process .
5. Applications
COG : The COG process is widely used in various display applications, including LCD TVs, computer monitors, and some older smartphone models. It is suitable for displays that do not require a high degree of flexibility or a very narrow bezel .
COF : The COF process is more commonly used in high – end smartphones, tablets, and other mobile devices that require a larger screen – to – body ratio and a more flexible design. It is also used in some OLED displays and foldable displays to achieve a slim and lightweight form factor .
COP : The COP process is mainly used in high – end smartphones and other devices that require a truly bezel – less or flexible display design. It is particularly suitable for OLED flexible screens, enabling the realization of innovative and advanced display designs .

Motorized Stage/Platform
Precise Movement Control : The ACF bonding machine features a motorized stage/platform that can be precisely controlled. After the vision system detects any misalignment, the motorized stage/platform can make micro-adjustments in the X, Y, and Z directions to bring the components into perfect alignment. This ensures that the ACF is accurately positioned between the two substrates to be bonded .
Bonding Head and Pressure Control
Uniform Pressure Distribution : The bonding head of the ACF bonding machine is designed to deliver uniform pressure across the ACF and bonding surfaces. It is usually made of heat-resistant materials like tungsten carbide to withstand the repeated high-temperature and high-pressure operations. The shape and size of the bonding head are customized according to the application, ensuring optimal contact with the components being bonded .

Temperature sensors are integrated to enable closed-loop control, maintaining the set temperature with a high degree of accuracy, typically within ±2°C. This precise temperature control is crucial for the proper activation of the ACF’s conductive particles, which in turn affects the alignment and bonding quality .
Heating Method : Different heating methods, such as constant heat and pulse heat, can be used depending on the specific bonding requirements. Pulse heating, for example, uses a transformer to generate low voltage and high current, which quickly heats the bonding area. This method allows for rapid heating and cooling, ensuring precise temperature control and efficient bonding. The choice of heating method can affect the alignment and bonding process, and the machine’s heating system is designed to provide the necessary flexibility .
Visual Inspection : After the bonding process, the machine performs a visual inspection using microscopy. This inspection checks for any signs of misalignment, air bubbles, or physical damage to the ACF. If any issues are detected, the machine can alert the operator or automatically correct the problem, ensuring that only properly aligned and bonded components are produced .
Electrical Testing : The machine also carries out electrical testing by applying a low-voltage electrical signal across the bonded areas to verify the conductivity of the connections established by the ACF. This step ensures that the alignment and bonding process have resulted in reliable electrical connections, and any defective bonds can be quickly identified and corrected .
In conclusion, the ACF bonding machine is a crucial tool in modern electronics manufacturing. Its ability to create reliable and high-quality connections between various components has made it an essential part of the production process for LCD panels, flexible circuits, and advanced display technologies.
