ACF G-450 COF/TAB Bonding Cleaning Liquid for Display Repair - 500ml

High-Performance Solvent for Display Panel Reconstruction

The ACF G-450 is a professional-grade chemical solvent specifically engineered for the high-precision requirements of display repair. During the bonding process of Chip-on-Film (COF) or Tape Automated Bonding (TAB) to glass substrates (LCD/OLED) or Printed Circuit Boards (PCB), residual Anisotropic Conductive Film (ACF) must be completely eradicated to ensure a successful repair.

G-450 is formulated to dissolve the epoxy resin and conductive particles of cured and uncured ACF without damaging the sensitive ITO (Indium Tin Oxide) tracks on the glass or the delicate copper traces on the COF flex cable. Its rapid-action formula reduces cleaning time by up to 40% compared to standard industrial thinners, making it an essential consumable for bonding technicians using specialized TAB bonding machines.

Technical Specifications & Product Overview

Key Performance Attributes

1. Precision Resin Dissolution

Unlike general-purpose cleaners, the G-450 focuses specifically on the chemical bonds of the thermosetting resins used in ACF. It softens the adhesive within seconds, allowing the technician to wipe away the residue without applying excessive mechanical pressure, which could crack the glass or tear the flex circuit.

2. ITO Track Preservation

One of the greatest risks in display repair is the oxidation or scratching of the Indium Tin Oxide tracks. G-450 is non-conductive and chemically stable when in contact with ITO. It ensures that the microscopic electrical paths remain intact, maintaining the signal integrity required for 4K and 8K panels.

3. Efficiency in TAB/COF Rework

In a high-volume repair environment, speed is critical. The G-450 is designed for a "Soak and Swipe" workflow. It penetrates the gap between the COF and the substrate quickly, ensuring that even the most stubborn, heat-cured ACF is loosened.
