From smartphones and tablets to TVs and computers, thin displays have become integral to our modern lives.
The display technology has undergone an impressive evolution. ACF has been fundamental to advancing display technologies, from LCD to OLED and flexible OLED. Let’s explore how display technology has evolved and examine ACF’s vital contribution to this journey.
The development of liquid crystal displays (LCDs) and the contribution of ACF
The LCD story began in the 1960s with a breakthrough discovery: liquid crystals could be used to create visual displays.
This technology found its first commercial applications in calculators and wristwatches during the 1970s, before expanding to larger formats like laptops, TVs, and monitors in the 1990s.
In LCD’s evolution, the push toward thinner profiles and higher resolutions was paramount.
ACF proved instrumental in this development by providing reliable circuit connections.
The technology delivers not only ultra-thin connections but also ensures robust bonding, exceptional reliability, and effective electrical isolation between adjacent circuits.
Its versatility extends to various substrates, enabling connections for Tape Carrier Package (TCP) and Chip on Film (COF) package signal outputs to displays, while also supporting Chip on Glass (COG) driver IC implementation.
The adoption of ACF has enabled higher resolutions through the miniaturization of circuits and contributed to thinner and lighter devices through the miniaturization of driver ICs.
LCD technology has developed rapidly since the discovery of the principles behind the use of liquid crystals for visual display. but it may not have been possible to achieve the modern thin and high-resolution displays without the evolution of ACF technology.
The emergence of OLED displays and the adaptation of ACF technology
As LCD technology matured, OLED emerged as the next generation of display technology.
After the Eastman Kodak Company announced the fundamental principles behind OLED in 1987, elements that emit their own light were used to achieve display technology that featured higher contrast than conventional LCD, wide viewing angles, thinness, and lightweight.
However, initial adoption was hampered by manufacturing costs and technical hurdles. Several factors contributed to OLED’s initially slow market penetration: prohibitive production costs, limited lifespan of blue organic electroluminescent elements, and image retention issues with static content.
Additionally, the complexity of OLED manufacturing processes and low yield rates presented significant challenges for mass production.
OLED technology made its breakthrough in the late 2000s, first appearing in small displays for smartphones and digital cameras as manufacturers overcame initial technical hurdles.
As the technology’s advantages became increasingly apparent, OLED displays expanded into large-screen TVs and flexible displays. Throughout this evolution, ACF technology adapted and advanced to accommodate OLED’s unique electrical properties and circuit designs.
Flexible OLED and ACF’s technical innovation: achieving Flex on Plastic (FOP) and Chip on Plastic (COP)
The advent of flexible OLED displays, utilizing polyimide substrates, marked a breakthrough in creating durable, highly flexible foldable displays.
While this technology opened new possibilities for flexible displays and wearable devices, it presented a significant challenge: maintaining reliable electrical connectivity with flexible substrates.
To address this challenge, innovative mounting technologies emerged, including FOP (mounting flexible FPC directly On Plastic) and COP (mounting hard IC On plastic substrate).
These solutions rely heavily on ACF technology to create secure connections between flexible plastic substrates and rigid driver ICs. ArrayFIX, represents a significant advance in this field. This particle-arrayed ACF technology delivers exceptional connection reliability in an extremely small area while maintaining electrical isolation between adjacent electrodes. By ensuring precise, dependable connections even in challenging environments, ArrayFIX has dramatically enhanced flexible OLED performance.
ACF’s technical features and its contributions to display technology
ACF technology stands as a cornerstone in advancing high-definition display technologies across LCD, OLED, and flexible OLED platforms. Its distinctive capabilities include ultra-fine pitch connections at pitches below 100 micrometers and remarkable adaptability to various electrode materials.
This versatility in accommodating different conducting materials, from ITO electrodes to metal electrode, has been instrumental in pushing the boundaries of display resolution and performance across all display technologies. The innovative ArrayFIX technology showcases the continued evolution of ACF. Its precise particle alignment capability enables optimized connections for specific electrode materials and pitches, driving further improvements in display performance. The technology’s success with both FOP and COP applications has made it essential for the advancement of flexible OLED technology.
ACF will support the display technology of tomorrow
Throughout the display industry’s evolution from LCD to OLED and flexible OLED, ACF has been a crucial enabler of technological progress.
Its contributions have been fundamental to achieving higher resolution displays, enhanced designs, and reliable connectivity solutions. Looking ahead, it remains committed to advancing ACF technology to support emerging display technologies such as microLED and silicon OLED, continuing our mission to enhance products that enrich our daily lives.
Anisotropic Conductive Film (ACF) serves as an adhesive for securing and electrically connecting electronic components, like integrated circuits (ICs), to circuit boards.
Originally introduced in 1977, ACF is now a staple in nearly all digital devices that employ flat panel displays—think smartphones, tablets, and high-definition TVs.
ACFs are typically used to connect the display panel to the flexible substrate that transmits signals to the panel or to the IC. Common applications of ACF include: COG (Chip-on-Glass), which connects the IC and glass substrate FOG (Flex-on-Glass), which connects the flexible substrate and glass substrate FOB (Flex-on-Board), which connects the flexible substrate and rigid substrate Other applications of ACF extend to smart cards, camera modules for CCDs (charge-coupled devices), and CMOSs (complementary metal oxide semiconductors). Shenzhen olian design and manufactur all the COG,COF,COP,FOG,FOB,FOP,FOF,TFOG,TFOF ACF bonding machines.
How ACFs can bond, conduct, and insulate
Anisotropic Conductive Film serves three primary functions simultaneously: adhesion, electrical conduction, and insulation. This unique capability allows manufacturers to connect a large number of pads at once.
Unlike traditional soldering, ACF enables fine pitch connections. The film is composed of conductive particles dispersed in a thermoset resin. A typical particle features a polymer core coated with nickel or gold, covered by an insulating layer.
When heat and pressure are applied, the opposing pads capture these particles. This process breaks the insulating coating to establish a vertical electrical connection. Particles trapped between pads remain insulated, preventing short circuits.
Key Technical Specifications:
Bonding Temperature: Ranges from 110°C to 180°C.
Film Thickness: Available from 10 to 45μm.
Film Width: Ranges from 0.5 to 20mm.
Roll Length: Available from 10 to 300m.
The ACF structure and bonding process
The bonding process is precise and efficient. Shenzhen Olian recommends following these steps for optimal results:
Clean the surface of the board to be attached.
Apply heat and pressure to the ACF with the release liner attached.
Peel off the release film carefully.
Align the pads of the IC chip to the ACF.
Apply heat and pressure again to finalize the bond.
ACFs are sold in reels, as shown in the photo below. They come in a wide range of film thicknesses. From 10 to 45μm, widths from 0.5 to 20mm, and lengths from 10 to 300m.
The figure below illustrates two types of ACFs: a three-layer type, where ACF is sandwiched between a protective film and a release film.
And a two-layer type where only the release film is used. Each type offers different benefits. The three-layer type reduces the risk of dust contamination, while the two-layer type eliminates the need to remove the protective film during bonding.
The advantages of bonding components with ACFs
As technology advances each year, circuit boards are becoming increasingly fine pitch, the area of connecting pads is shrinking, and the spacing between them is narrowing.
While reflow soldering and connector components are traditionally used for bonding electronic components such as ICs to circuit boards, ACFs provide a solution to these trends.
However, a disadvantage of ACF is that it is challenging to bond components of different shapes simultaneously, which is common in reflow soldering.
Also, since ACF is an adhesive, it cannot be freely removed and reattached like mechanical connectors.
Why Choose ACF?
Benefits of ACF
Can bond components on glass substrates
Enables batch connections of multiple pads
Enables fine pitch connections
Pb-free
Quick bonding at relatively low temperatures
Thinner bonding area
The history of ACF and its innovation
Dexerials has been continually enhancing ACF since its introduction in 1977. Initially, the conductive particles used were carbon fiber and solder particles. However, in 1988, Dexerials developed particles plated with nickel and gold.
By the 1990s, Dexerials had successfully developed a technology to coat the surface with insulating material.
As digital devices have evolved towards higher definition, Dexerials has adapted to the trend of fine pitch connections by reducing the particle size from 5μm to 2.8μm.
In 2014, Dexerials developed a technology to uniformly align conductive particles in thermosetting resin.
And in 2016, began marketing the product as “particle-arrayed Anisotropic Conductive Film” (ArrayFIX). This product contributes to the miniaturization, slimming design of digital devices, and higher resolution displays.
Selecting the best type of ACF
When selecting the best ACF, several factors should be considered, including the type of adherend, connection area, distance between pads, height of pads, and heat resistance.
ACF is composed of either epoxy resin or acrylic resin that cures with heat. we recommends acrylic ACF for applications where Flexible Printed Circuits (FPCs) and substrates (PCBs or glass substrates) are to be bonded, and where the design is intended to be reworked after the main bonding. (Please note that Dexerials does not recommend reworking itself. Dexerials advises that rework should only be done after reliability evaluations have been conducted to ensure that there are no issues.) Dexerials does not recommend ACF with epoxy resin if there is a possibility that the customer will rework. The primary reason is that it often damages the substrate to be reworked. This is because cured epoxy resin does not dissolve in solvents, and the process involves scraping off the residue.
Reworking after bonding typically involves heating the bonding area with a heat gun, hot iron, hot plate, etc., and then peeling off the FPC. Afterward, the cured resin residue between the pads on the board should be carefully removed using a solvent such as Methyl Ethyl Ketone (MEK) or N-Methyl-2-pyrrolidone (NMP) and a cotton swab. However, Dexerials does not recommend reusing FPCs because FPCs often curl during the peeling process and cleaning the resin residue between the pads on the FPC side is challenging.
With over 40 years of leadership in ACF technology, Dexerials can provide services including the initial setup, proposing an appropriate ACF, and post-connection analysis and evaluation. If you have any questions about ACF application, please feel free to contact us.

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:
LCD Module Assembly Process Flow

8
Final inspection & testing
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.

Key Technical Specifications to Evaluate
When comparing ACF bonding machines from different manufacturers, these are the non-negotiable specifications that determine production capability:
🔧 Alignment Accuracy

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
Temperature range: Typically 100–280°C
Temperature uniformity across bonding head: ±2°C or better
Ramp-up speed: Fast heating reduces process time and ACF pre-curing risk
Temperature measurement: Thermocouple embedded in bonding tool vs. infrared sensing
Precision temperature control is critical because ACF’s conductive particles must be compressed at the exact thermosetting temperature — too hot causes ACF degradation, too cold means incomplete curing and unreliable connections.
💪 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.
