A FOG (Film On Glass) bonding machine is a critical piece of equipment used in the electronics industry, particularly for the assembly of liquid crystal displays (LCDs) and other display technologies. It is designed to establish a stable mechanical and electrical connection between a flexible printed circuit (FPC) and a glass substrate, such as an ITO (Indium Tin Oxide) panel
Key Features and Specifications
ACF Application: The machine applies Anisotropic Conductive Film (ACF) to the substrate with high precision. This ensures that the ACF is accurately positioned to facilitate a reliable bond.
Precision Alignment: Advanced vision systems are used to align the FPC with the glass substrate. This ensures sub-micron alignment accuracy, which is crucial for maintaining electrical and mechanical integrity.
Bonding Process: The bonding process involves applying heat and pressure to the assembly. The machine typically uses a thermocompression bonding method, where the ACF is crimped to bond the FPC to the glass substrate.
Technical Specifications:
Bonding Accuracy: ± 10µm (3σ) from pre-pressing to final crimping.
Temperature Range: RT to 499°C.
Pressure Range: 3 to 40 Kgf.
