Here is a comprehensive overview of the parts and accessories used in ACF bonding processes:
ACF Tape is the core material used in the ACF bonding process. It is an epoxy adhesive system filled with conductive particles that provide electrical interconnection between pads through the film thickness (z-direction). The conductive particles are distributed far apart to ensure electrical insulation in the plane direction (X&Y) of the film. ACF tape is available in various models and is specific to the application for which it is designed. For example, ACF designed for flex-on-glass (FOG) assembly is usually not suitable for chip-on-glass (COG) or chip-on-film (COF) applications.
The Hot Bar or Thermode is the primary tool used to apply heat and pressure during the ACF bonding process. Hot bar bonding systems are designed to heat the hot bar to a specific temperature using low voltage electricity, which temperature is fed back to the controller via a thermocouple. The hot bar is brought into contact with the ACF film over the bonding pad, heated to the bonding temperature, and held for a specified time. This process produces the connection between the ACF tape and the components.
Bonding Heads are designed to hold the components and position the ACF tape correctly with the conductive pads on the PCB or other components. They ensure that the bonding process is accurate and consistent. Bonding heads can be manual or automated, depending on the specific requirements of the bonding process.
