As a core component of the Module (LCD/OLED) manufacturing process, the COF Bonding Machine enables precise, reliable, and high-throughput interconnection between the display panel and driver ICs via flexible printed circuits (FPCs), playing a critical role in delivering today’s high-performance visual experiences.
A COF Bonding Machines is an automated precision system designed to bond Chip-on-Film (COF) packages—where driver ICs are mounted directly onto thin, flexible polymer substrates—onto the glass display panel. This process, known as COF bonding, is essential for high-resolution displays such as QHD, 4K, and beyond, especially in large-size monitors, TVs, and high-end commercial screens.
The machine integrates advanced technologies including:
● High-accuracy vision alignment systems (CCD/CMOS)
● Thermocompression bonding with precise temperature and pressure control
● ACF (Anisotropic Conductive Film) application and curing
● Real-time misalignment (M/A) inspection and defect detection
It operates primarily in the Module (MOD) stage, following Cell assembly and preceding final aging and packaging.
With the rise of Oxide backplane technology and Dual Gate driving architectures, leading panel manufacturers are reducing the number of COFs required per panel—such as cutting from 8 to 4 COFs on a 27” QHD monitor—thereby simplifying the bonding process and improving yield. However, each remaining COF bond must be flawless, making the precision and reliability of the COF Bonding Machine more critical than ever.
The COF bonding process typically includes:
1. COF Pre-processing: COF reels are loaded and cut into individual units.
2. ACF Lamination: ACF film is precisely attached to the panel’s bonding area.
3. COF Alignment: The COF is picked up, aligned with sub-micron accuracy to the panel’s gold fingers.
4. Thermocompression Bonding: The COF is pressed onto the panel under heat and pressure, activating the ACF to form conductive pathways.
5. Post-Bond Inspection: Automated vision systems check for misalignment, insufficient adhesion, or short circuits.
● Ultra-High Precision Alignment: Achieves alignment accuracy within ±5μm, essential for fine-pitch ICs in high-PPI displays.
● High Throughput: Modern machines can process up to 1,000+ panels per hour, supporting mass production demands.
● Dual-Side & Multi-COF Capability: Supports complex layouts with multiple COFs on top/bottom or dual-side bonding.
● Low Defect Rate: Integrated AOI and M/A inspection systems detect bonding errors in real time, minimizing downstream failures.
● Process Flexibility: Adaptable to various panel sizes (from 10” to over 75”) and technologies (LCD, OLED, MicroLED).
● Smart Factory Integration: Equipped with SECS/GEM interfaces for seamless connection to MES systems, enabling Industry 4.0 compliance.
As highlighted in recent industry trends, the reduction in COF count—enabled by Oxide + Dual Gate technology—brings significant benefits to the bonding process:
● Simplified Bonding Layout: Fewer COFs reduce complexity in alignment and pressure distribution.
● Reduced Risk of Bonding Defects: Lower COF count decreases the probability of M/A (misalignment) and ACF voids.
● Improved Equipment Uptime: Less frequent tool changes and simpler handling increase overall equipment effectiveness (OEE).
● Lower Material Cost: Reduced COF and PCB usage directly cut BOM costs.
However, this also demands higher precision per bond, as each remaining COF carries more signal load—making the performance of the COF Bonding Machine even more crucial.
● Monitors & TVs: High-resolution desktop and large-format displays benefit from stable, high-yield COF bonding.
● Commercial Displays: Digital signage, kiosks, and interactive whiteboards rely on durable COF interconnections.
● Industrial & Medical Equipment: Requires long-term reliability under varied environmental conditions.
● Automotive Displays: As dashboards adopt larger, curved, or multiple screens, COF bonding ensures signal integrity and space efficiency.

Control: Utilizing servo-controlled dispensing arms and programmable logic controllers (PLC), we strictly manage the dispensing path, volume, and evenness of the glue. This prevents corrosion of ITO lines and strengthens the bond between the FPC and the LCD, ensuring long-term product reliability.
For modules requiring backlighting, our automated assembly lines ensure perfect optical alignment.
Assembly: This involves the precise stacking of optical films, frame assembly, and the application of hot-melt adhesives.
Packaging: We provide automated solutions for the final stages of production, including protective film application and automated boxing, ensuring the product is protected for shipment.
Quality is our DNA. We integrate AOI systems at critical junctures (post-bonding and post-lamination) to guarantee zero-defect delivery.
Detection: Our vision systems perform rigorous functional and cosmetic testing. They identify microscopic defects such as particles, scratches, bubbles, and Mura defects that are invisible to the naked eye, ensuring only flawless products proceed to the next stage.

A COP bonding machine is the hidden engine behind the ultra-narrow chins of foldable phones, curved smart-watches and dashboard OLEDs.
COP means “Chip On Pi” (or “Chip On Plastic”): the display driver IC is bonded to a flexible polyimide/plastic film, then the film—and the IC—are folded 180° underneath the screen so the bezel almost disappears.
The machine that executes this microscopic fold-and-bond must deliver sub-micron alignment, single-degree thermal control and gram-level force accuracy—all in a 3-second cycle.
Keywords: “COP bonding machine”, “Chip On Pi bonder”, “flexible OLED IC bonding”, “ACF COP machine”, “foldable phone bonding equipment”, “narrowest bezel bonding”
A COP bonding machine is a high-precision pulse-heat press that attaches a gold-bumped driver IC to a thin polyimide (Kapton) or specialty plastic substrate using anisotropic conductive film (ACF).
After bonding, the plastic tail is folded behind the active area, hiding the IC and releasing valuable “chin” space.
The same machine also reworks defective panels by removing the old IC and rebonding a new one, saving flexible OLED assembly.
Modern COP bonders achieve ±1 µm alignment, ±0.5 °C temperature stability and 0.1 kg force resolution on substrates as thin as 25 µm and as narrow as 0.8 mm.
COG (Chip-On-Glass) parks the IC on the glass itself, eating 3–4 mm of chin length.
COF (Chip-On-Film) moves the IC to a flex tail, but the tail still exits sideways before folding.
COP bonds the IC to a plastic film that can be folded 180° with a 0.2 mm bend radius, shrinking the bottom bezel to 0.9 mm and enabling 95 % screen-to-body ratios in flagship smartphones like iPhone X and OPPO Find X.
Plastic substrates also absorb thermal expansion mismatch better than glass, improving reliability in automotive and wearable applications.
Bonding Head: Titanium alloy, diamond-lapped to 0.3 µm flatness, plasma-nitrided to 70 HRC, anti-stick diamond-like-carbon (DLC) coating lasts 200,000 cycles.
Pulse Heater: 600 W cartridge, embedded K-type thermocouple, ramp rate 200 °C/s, overshoot < 0.5 °C.
Force Loop: Voice-coil actuator, 24-bit encoder, 0.1 N resolution, 2 ms response; active gravity cancellation for 25 µm substrates.
Vision System: 12 MP global-shutter CMOS, telecentric lens, coaxial LED + low-angle side light, sub-pixel edge detection repeatable to 0.2 µm.
Motion Stage: Cross-roller bearing, 0.05 µm linear encoder, servo feedback at 20 kHz, granite base with passive vibration isolation.
Software: Real-time Linux kernel, recipe encryption, SECS/GEM, OPC-UA, MES traceability, AI predictor for heater life.
Smartphones & Tablets: iPhone, Galaxy Fold, Huawei Mate X bond display driver and touch MCU on COP tail to achieve 0.9 mm chin
.
Wearables: Apple Watch, Xiaomi Band use COP to fold IC under OLED, creating curved edge with zero bezel.
Automotive: Curved instrument clusters and 15 inch OLED infotainment displays rely on COP for thermal cycling survival from −40 °C to +105 °C.
Medical: Flexible diagnostic patches and surgical monitors demand biocompatible polyimide and COP bonding.
Industrial & Military: Rugged handhelds and avionics displays exploit COP for shock, altitude, and fungus resistance per MIL-STD-810.
