Leading ACF Bonding Machine Manufacturer for LCD Displays
Leading ACF Bonding Machine Manufacturer for LCD Displays
What Is ACF Bonding and Why It Matters for LCD Displays
Anisotropic Conductive Film (ACF) bonding is a key process in assembling and repairing LCD, OLED, and other flat panel displays. It uses a specialized adhesive film containing conductive particles to create reliable electrical connections under controlled heat, pressure, and time—without short-circuiting adjacent traces.
This technology is essential for processes such as:
COG (Chip on Glass)
COF (Chip on Film)
FOG (Film on Glass)
FOB (Film on Board)
TAB/OLB and more

High-Precision Rework System for Defective COG and COF Bonds on Large LCD Panels
High-Precision Rework System for Defective COG and COF Bonds on Large LCD Panels
The OL-CRW017-2 by Olian Automatic Equipment Co., Ltd. is an advanced automatic repair machine designed for reworking defective COG (Chip-on-Glass) and COF (Chip-on-Film) bonds on display modules up to 17 inches. Equipped with two high-resolution cameras and supporting A+P+M (Alignment + Pre-press + Main-press) functionality, it enables precise, repeatable thermal re-bonding without damaging surrounding components.
This system is ideal for display module manufacturers, quality control centers, and repair lines where yield recovery and process consistency are critical. It handles both COG ICs and COF flex circuits—making it a versatile solution for modern LCD and touch panel production.
Dual-Camera Vision System for Accurate Alignment
The machine features two independent camera channels, each with adjustable magnification and coaxial LED lighting. Operators use live video feeds to align bonding marks before repair. The dual-view setup allows simultaneous inspection of chip and pad alignment from optimal angles—reducing parallax error and improving rework success rates.
All alignment is performed manually via intuitive controls. Once alignment is confirmed as “OK,” the operator initiates the cycle using a dual-hand start mechanism—a key safety feature that prevents accidental activation.
Three-Stage Repair Process: A + P + M
The OL-CRW017-2 executes a complete three-stage thermal rework sequence:
Alignment (A): Visual confirmation of mark-to-mark registration using dual cameras.
Pre-press (P): A low-force, low-temperature press temporarily fixes the chip or COF in place.
Main-press (M): Full heat and pressure are applied to reflow the ACF (Anisotropic Conductive Film) and form a reliable electrical bond.
Temperature is adjustable from room temperature to 400°C, with surface uniformity maintained within ±5°C across the press head. Bonding time ranges from 0.1 to 99.9 seconds. Force output is precisely controlled to match material sensitivity—preventing glass cracking or flex damage.
Standard press heads are made of wear-resistant tungsten steel. Custom sizes are available upon request.
Safety and Operational Reliability
The machine includes multiple safety layers:
EMO (Emergency Stop): Cuts power to all servos instantly. Motion units can then be moved manually.
Machine Interlock: Triggers audible alarm (buzzer) and on-screen warning if errors occur.
Hazard Labels: Clear stickers mark high-risk zones (e.g., hot surfaces, pinch points).
Three-Color Signal Tower: Shows real-time status—green (ready), yellow (running), red (fault).
These features ensure safe operation in busy production environments.
Mechanical and Environmental Requirements
The system supports panels up to 17 inches with standard thicknesses used in industrial and consumer displays. It requires a clean, static-controlled workspace with stable temperature and humidity. Compressed air must be clean, dry, and supplied at 0.4–0.7 MPa. Power input is single-phase AC 220V ±10%.
The machine frame is robust and finished in industrial-grade coating. All moving parts use precision linear guides and servo-driven actuators for smooth, repeatable motion.
Support, Training, and Warranty
Olian provides one Chinese-language operation manual. On-site training lasts one day and covers:
Machine installation and calibration
Operation, parameter setup, and alignment
Common fault diagnosis and resolution
Replacement of consumable and wear parts
Training duration can be adjusted by mutual agreement.
The machine comes with a 12-month warranty under normal use. Damage caused by misuse, improper environment, or force majeure is excluded. During the warranty period, if remote support fails, an engineer will arrive on-site within 72 hours. Lifetime technical support is available beyond the warranty term.
