Anisotropic Conductive Film (ACF) is a specialized adhesive material. It contains conductive particles within an insulating resin. This unique structure allows vertical electrical conductivity. Simultaneously, it maintains horizontal insulation between circuits. ACF is essential for modern flat panel displays. It connects delicate components without short circuits. The film provides both adhesion and conduction. This dual function is critical for reliability. Olian Automatic utilizes this advanced material effectively. Our processes optimize the ACF performance. This ensures long-lasting display connections.
Core Bonding Processes Explained
Several key bonding methods use ACF technology. Chip-on-Glass (COG) bonds IC chips directly to glass panels. This is common in LCD manufacturing. Chip-on-Film (COF) connects ICs to flexible circuits. This allows for thinner display bezels. Flex-on-Glass (FOG) attaches flexible boards to glass substrates. Flex-on-Board (FOB) connects flex circuits to rigid PCBs. Tape Automated Bonding (TAB) links TCP tapes to displays. Each process requires specific parameters. Olian Automatic masters all these techniques. We provide versatile solutions for various needs.
Glossary of ACF Bonding Terms
ACF (Anisotropic Conductive Film)
ACF stands for Anisotropic Conductive Film. It is a specialized adhesive material used in display assembly. The film contains conductive particles trapped in an insulating resin. It provides electrical conductivity in the vertical direction only. Simultaneously, it ensures electrical insulation in the horizontal direction. This unique property prevents short circuits between fine pitches. ACF also offers strong adhesion between components. It is the core material for COG, COF, and FOG bonding.
COG (Chip-on-Glass) Bonding
COG stands for Chip-on-Glass bonding. This process connects an IC chip directly onto a glass substrate. It is widely used in LCD and OLED panel manufacturing. The method eliminates the need for intermediate flexible tapes. COG bonding saves space and reduces module thickness. It requires precise alignment and controlled heat pressure. ACF is typically used as the interconnect material. This technique is common for source and gate driver ICs.
COF (Chip-on-Film) Bonding
COF stands for Chip-on-Film bonding. This technique mounts IC chips directly onto a flexible film. The film is usually a Tape Carrier Package (TCP). COF allows for very narrow display bezels. It enables the bending of the film under the panel. This creates a “bottom bezel” free design. The flexible circuit connects the glass to the main PCB. It supports high-resolution displays with many signal lines.
FOG (Flex-on-Glass) Bonding
FOG stands for Flex-on-Glass bonding. This process attaches a Flexible Printed Circuit (FPC) to a glass panel. It serves as the interface between the rigid glass and external electronics. FOG bonding is essential for transmitting signals to the display. It uses ACF to ensure reliable electrical connection. The process requires high precision to align fine circuit traces. It is a standard step in LCD module assembly.
FOB (Flex-on-Board) Bonding
FOB stands for Flex-on-Board bonding. This method connects a flexible circuit (FPC) to a rigid Printed Wiring Board (PWB). It bridges the gap between flexible and rigid electronics. FOB is often used in the final assembly stage. It links the display module to the main system board. The connection must withstand mechanical stress and bending. ACF provides both electrical continuity and mechanical strength.
COP (Chip-on-Plastic) Bonding
COP stands for Chip-on-Plastic bonding. Although less prominent in the diagrams, it is listed in the text. This technology bonds IC chips directly onto plastic substrates. It is increasingly used in flexible OLED displays. COP allows the entire display to be bendable or foldable. It replaces glass with polyimide or similar plastics. The bonding process requires lower temperatures to protect the plastic.
TCP (Tape Carrier Package)
TCP refers to Tape Carrier Package. It is a type of flexible interconnect technology. TCP carries IC chips on a thin polymer tape. It is the primary component used in COF bonding. The tape has fine metal leads for electrical connections. TCP allows for high-density packaging of driver chips. It acts as the bridge between the glass and the PCB.
FPC (Flexible Printed Circuit)
FPC stands for Flexible Printed Circuit. It is a lightweight, bendable electronic circuit board. FPCs are used in FOG and FOB bonding processes. They replace rigid cables to save space and weight. The circuit pattern is etched onto a flexible substrate. FPCs can route signals through tight spaces in devices. They are crucial for connecting moving or folded parts.
PWB (Printed Wiring Board)
PWB stands for Printed Wiring Board. It is commonly known as a rigid PCB. PWBs serve as the main backbone for electronic components. In display modules, PWBs receive signals from the FPC. FOB bonding connects the flexible display output to this board. PWBs provide mechanical support and complex circuit routing. They are essential for the final electronic assembly.
IC Chip (Integrated Circuit Chip)
IC Chip stands for Integrated Circuit Chip. In display bonding, these are typically driver ICs. They control the pixels on the screen to create images. The chip contains thousands of microscopic connection points. These points must align perfectly with the substrate pads. The IC is the “brain” of the display panel. Proper bonding is critical for its functionality.
Glass (Panel/Substrate)
Glass refers to the display panel substrate. It is the base material for LCD and OLED screens. The glass surface holds the pixel matrix and electrodes. COG and FOG bonding happen directly on this surface. The glass is fragile and requires careful handling. Cleanliness is vital before applying ACF. It provides a flat, stable platform for components.
Conductivity
Conductivity refers to the flow of electrical current. In ACF bonding, this happens vertically through the film. Conductive particles create the path between the chip and substrate. This ensures the signal reaches the display pixels. High conductivity is necessary for clear image quality. The resistance must be low and stable.
Insulation
Insulation prevents unwanted electrical flow. In ACF, the resin insulates adjacent signal lines horizontally. This prevents short circuits between neighboring traces. High insulation resistance is critical for fine-pitch connections. It ensures that signals do not cross paths. Reliable insulation guarantees the display functions correctly.
Adhesion
Adhesion is the mechanical sticking force of the bond. The ACF resin cures to hold components together firmly. Strong adhesion protects against moisture and dust ingress. It withstands thermal expansion and mechanical shock. Good adhesion ensures the long-term reliability of the device. It prevents the chip or film from peeling off.
Temperature, Pressure, Time
These are the three critical process parameters. Temperature activates the chemical curing of the ACF. Pressure forces the conductive particles into contact. Time determines the duration of the heat application. All three must be precisely controlled for a good bond. Incorrect settings lead to open circuits or weak joints. Olian Automatic systems optimize these variables perfectly.
TAB (Tape Automated Bonding)
TAB stands for Tape Automated Bonding. It is an older term often associated with TCP input. It refers to bonding the tape carrier to the LCD glass. The process uses heat and pressure to connect leads. TAB enables high-speed automated manufacturing. It is the precursor to modern COF technology.
Plasma Display
Plasma Display refers to PDP (Plasma Display Panel) technology. The images show FPC bonding for plasma displays. This indicates ACF’s versatility across different display types. Plasma panels also require reliable flex-to-glass connections. The bonding principles remain similar to LCDs. It demonstrates the broad application of Olian’s technology.
The Precision Bonding Workflow
The ACF bonding process follows strict steps. First, technicians clean the glass substrate thoroughly. Next, they apply the ACF material carefully. Then, they peel off the protective release film. Precise alignment of the IC chip follows. Finally, heat and pressure are applied simultaneously. This activates the adhesive and conductive particles. The bonding tool ensures uniform pressure distribution. Temperature and time are strictly controlled. This five-step process guarantees perfect connections. Olian Automatic automates this workflow for consistency.
Applications Across Display Sizes
Our ACF bonding solutions serve diverse markets. Small and medium-sized displays utilize COG technology. Smartphones and tablets benefit from this method.

Frequently Asked Questions (FAQ)
What Is ACF Bonding and Why Does It Matter?
In the world of LCD and OLED display manufacturing, there’s a microscopic process that makes every screen you use possible — ACF bonding.
ACF stands for Anisotropic Conductive Film — a specialized adhesive material that conducts electricity vertically (through its thickness) while remaining electrically insulating horizontally (across its surface). Originally developed by Sony Chemical (now Dexerials) in 1977, ACF has become the indispensable “neural synapse” of modern display panels, enabling electrical connections between driver ICs, flexible printed circuits (FPCs), and glass substrates at pitches as fine as 30 micrometers or below.
Think of it this way: within an area roughly the size of a fingernail, hundreds of electrical contacts must be simultaneously connected with micron-level precision — that’s exactly what ACF bonding achieves. Without this technology, the smartphones, tablets, laptops, televisions, automotive displays, and industrial HMI screens we rely on every day simply couldn’t exist.
And the machine that makes this process happen? That’s the ACF bonding machine — the precision equipment that applies temperature, pressure, and alignment control to create reliable, repeatable electrical interconnections using ACF material.
The Critical Role of ACF Bonding Machines in LCD Display Production
LCD display production is a multi-stage manufacturing process where the bonding stage is arguably the most precision-demanding step. Here’s where ACF bonding machines fit in the production flow:

Inspection equipment
As the table shows, ACF bonding machines are involved in at least 2–3 critical stages of LCD module assembly. The quality of bonding directly determines:
✅ Display image stability — no flickering, line defects, or dead pixels
✅ Signal transmission reliability — consistent electrical conductivity at every contact point
✅ Product lifespan — resistance to thermal cycling, mechanical stress, and environmental aging
✅ Yield rate — reducing rework and scrap directly improves production economics
A single bonding defect — a misaligned IC, insufficient ACF compression, or a trapped particle short — can render an entire display panel defective. This makes the choice of ACF bonding machine manufacturer a strategic production decision, not merely a procurement task.
Types of ACF Bonding Processes: COG, COF, FOG Explained
Understanding the different bonding configurations is essential when selecting equipment. Here’s a detailed breakdown:
1. COG (Chip on Glass) Bonding
COG bonding attaches a bare driver IC chip directly onto the ITO (Indium Tin Oxide) electrode pads on the LCD glass substrate using ACF as the interconnect medium.
Process Steps:
ACF film is laminated onto the glass bonding area
The driver IC is aligned to the glass electrode pads using a high-precision vision alignment system
Pre-bonding (temporary attach) with low pressure
Main bonding with controlled temperature (typically 180–220°C), pressure (typically 15–30 MPa), and time (typically 8–15 seconds)
ACF resin thermosets, conductive particles are compressed to form vertical electrical pathways
Key Challenges:
Pin pitch down to 30 μm or finer requires sub-micron alignment accuracy
Uneven pressure distribution causes connection reliability issues
Thermal management must prevent glass substrate stress
2. COF (Chip on Film/FPC) Bonding
COF bonding mounts the driver IC onto a flexible printed circuit (FPC) film first, then the COF package is bonded to the glass substrate. This configuration is increasingly preferred for:
High-resolution displays with narrow bezels
Foldable/flexible OLED displays
Displays requiring bendable interconnects
Advantages over COG:
The IC can be bent around the display edge → narrower bezel
Better thermal dissipation through the FPC substrate
Easier repair — the entire COF module can be replaced
3. FOG (FPC on Glass) Bonding
FOG bonding connects the flexible printed circuit board (FPC) to the glass substrate terminal area. This is the signal bridge between the display panel and the external system (motherboard, T-CON board, etc.).
Process Flow (after COG is completed):
Glass terminal area is cleaned
ACF is laminated onto the glass bonding pads
FPC is aligned to the glass pads
Pre-bond → Main bond (thermocompression)
FOG is often the final electrical interconnection step before the LCD module enters final assembly and testing.

Standard
±15 μm
FOG bonding, moderate-pitch applications
High-Precision
±5 μm
COF bonding, fine-pitch LCD/OLED
Ultra-High-Precision
±2 μm or better
COG bonding, finest pitch ICs
Tip from bonding-machine.com: Always verify alignment accuracy under actual production conditions (not just laboratory specs). Request a live demonstration with your specific product dimensions.
🌡️ Temperature Control

💪 Pressure Control
Pressure range: 2–5 MPa (adjustable for different ACF types and substrates)
Pressure uniformity: ±5% or better across bonding area
Parallelism of bonding head: Critical for uniform particle compression
Force measurement: Load cell-based real-time monitoring preferred
⏱️ Process Time & throughput
Single bond cycle time: 6–20 seconds (main bond)
UPH (Units Per Hour): Ranges from 300 to 1,200+ depending on machine configuration
Pre-bond + Main-bond sequential time: Total cycle including alignment, pre-bond, main-bond, and cooling
👁️ Vision Alignment System
The vision system is the “eyes” of the bonding machine. Key parameters:
Camera resolution: Minimum 2 megapixels; 5+ MP for ultra-fine pitch
Magnification: Adjustable (typically 2x–10x)
Alignment mark recognition: Support for multiple mark types (cross, circle, L-shape, custom)
💡 A machine that costs 20% more but delivers 3% higher yield can save hundreds of thousands of dollars annually on a high-volume production line.
