What is the main advantage of flexible COF bonding?
The primary advantage of flexible COF bonding is its ability to support narrow-bezel and foldable display designs. Because the IC is mounted on a flexible film, the circuit can be bent to the back of the display panel (IC folding), significantly reducing the bottom bezel size and enabling innovative form factors like curved and foldable smartphones.
What role does ACF play in the COF bonding process?
Anisotropic Conductive Film (ACF) is the core adhesive material in COF bonding. It contains microscopic conductive particles trapped in a resin. During the bonding process, heat and pressure crush these particles between the COF bumps and the substrate electrodes, creating a vertical electrical path while maintaining horizontal insulation to prevent short circuits.
What are the critical parameters for high-yield COF bonding?
Achieving a high yield in flexible COF bonding requires precise control over three main variables: Temperature (to activate the ACF resin), Pressure (to ensure particle deformation and contact), and Time (duration of the bond). Additionally, high-precision visual alignment systems are essential to ensure accurate placement of the COF tape.
