TAB Bonder

TAB Bonder

A TAB bonder—short for Tape Automated Bonding bonder—is the precision heart that welds the copper leads of a continuous polyimide tape (TAB) onto a glass panel, PCB, or flexible substrate using anisotropic conductive film (ACF) or thermosonic/ultrasonic energy. Inside every 8-K TV, curved automotive cluster, or medical sensor you see today, a TAB bonder has aligned 26 µm-pitch copper fingers to ITO pads within ±1 µm and created thousands of vertical contacts in under three seconds. This guide explains physics, hardware, software, specs, applications, trends, and maintenance so Google instantly ranks you for “TAB bonder”, “TAB bonding machine”, “automatic TAB bonder”, “ACF TAB bonding”, and every high-value permutation.

1. Why “TAB” Still Dominates Large Displays

COG (Chip-On-Glass) works for phones, but 65-inch OLED panels need driver ICs that dissipate watts of heat—too much for direct glass mounting. TAB moves the IC onto a continuous copper-clad polyimide reel that can dissipate heat, fold 180°, and be replaced during repair. The TAB bonder is the machine that welds that tape’s outer leads to the glass edge, enabling 0.9 mm bezels and AEC-Q100 Grade 0 (−40 °C to +105 °C) survival without a single connector contact.

2. What Exactly Is a TAB Bonder?

A TAB bonder is a servo-driven, vision-guided, heat-and-pressure press that:

1. Laminates anisotropic conductive film (ACF) onto glass or PCB pads,
2. Indexes a continuous TAB reel so the outer leads sit over those pads,
3. Aligns copper fingers to ITO within ±1 µm,
4. Welds them at 160–200 °C and 0.8–1.2 MPa for ~2 s,
5. Repeats every 2.8 s while the reel indexes ±5 µm over 300 mm stroke.

The result is a flexible, lead-free, foldable interconnect that survives thermal cycling, vibration, and 200,000 bend cycles.

3. Physics: Why ACF + Controlled Heat Works

• Copper Leads 12–35 µm thick are etched on the polyimide tape.
• ACF Film 25–45 µm thick contains 3–10 µm nickel or gold-coated spheres.
• Controlled Heat: 160–200 °C for ~2 s deforms spheres between lead and ITO, creating < 30 mΩ vertical contacts while remaining > 1 GΩ isolated horizontally.
• Cool Under Load: Water-cooled block drops to < 60 °C while pressure holds, locking particles in place.

The bonder controls temperature ramp, force profile, and dwell time to within 1 %; any drift triggers AI-based closed-loop correction.

1. Reel Indexing: Servo motor advances polyimide tape; dancer-arm tension control maintains < 0.5 N fluctuation.
2. ACF Lamination: Precision cutter feeds 1–3 mm strip; heated roller tacks film to glass ITO at 80 °C, 0.2 MPa.
3. Vision Alignment: Dual 12 MP cameras capture fiducials on leads and glass; deep-learning algorithm calculates offset in X, Y, θ, and scale within ±1 µm @ 3σ in < 200 ms .
4. Pre-Bond: Head descends at 60 °C and 0.1 MPa to tack the tail; system verifies overlap ≥ 98 %.
5. Heat & Pressure Bond: Titanium head ramps to 160–200 °C; pressure rises to 0.8–1.2 MPa; spheres deform and capture.
6. Cool Under Load: Water-cooled block drops to < 60 °C while pressure holds, preventing particle relaxation.
7. Fold Test (Optional): Mandrel bends tail 180° with 0.2 mm radius; vision checks for trace cracking or ITO micro-cracks.

COP Bonder

COP Bonder

A COP bonder—short for Chip-On-Plastic bonder—is the precision heart that welds a bare driver IC onto a foldable plastic substrate (polyimide, PET, or PEN) and then bonds that plastic tail to glass, flex, or board. Inside every foldable phone, curved automotive cluster, and ultra-slim OLED TV you see today, a COP bonder has aligned gold bumps to copper leads within ±1 µm and created thousands of vertical contacts in under three seconds. This guide explains physics, hardware, software, specs, applications, trends, and maintenance so Google instantly ranks you for “COP bonder”, “COP bonding machine”, “automatic COP bonder”, “ACF COP bonding”, and every high-value permutation.

---

1. Why “COP” Matters

COp stands for Chip-On-Plastic (often written Chip-On-Pi for polyimide). Instead of parking the driver IC on rigid glass (COG) or a glass-backed flex (COF), COp places the die directly onto a foldable plastic substrate—polyimide (PI), PET, or PEN—as thin as 25 µm. The plastic can be bent 180° with 0.2 mm radius, enabling 0.9 mm bezels and 200,000-fold cycles in foldable phones . The same machine later bonds the plastic tail to glass (FOG) or to another flex (FOF), all without solder, connectors, or added thickness.

2. Physics: Low-Temp ACF + Foldable Plastic

• Gold or Copper Bumps 5–25 µm high are plated on the IC during wafer-level bumping.
• ACF Film 25–45 µm thick contains 3–10 µm nickel or gold-coated spheres.
• Low-Temp Recipe: 140–180 °C, 0.6–1.0 MPa, 1.5 s pulse (PET Tg ~ 150 °C).
• Fold Radius: 0.2 mm without trace cracking; spheres remain locked after 200,000 bends .
• Vertical Resistance: < 30 mΩ per bump; lateral isolation > 1 GΩ.

The bonder controls temperature ramp, force profile, and dwell time to within 1 %; any drift triggers AI-based closed-loop correction.

COG bonder

COG Bonder: Chip-On-Glass Bonding Technology

The sleek, vibrant displays on our modern devices, from smartphones to car dashboards, are marvels of micro-engineering. At the heart of these displays lies a critical and precise assembly process: Chip-On-Glass, or COG. This technology is enabled by a specialized machine known as a COG Bonder. This article provides a detailed exploration of COG Bonders, explaining their function, process, and indispensable role in the electronics industry.

What is a COG Bonder?

A COG Bonder is a high-precision industrial machine designed to mount bare semiconductor chips directly onto a glass substrate, typically a liquid crystal display (LCD) or organic light-emitting diode (OLED) panel. Unlike traditional methods that use packages and sockets, COG bonding creates a direct, space-saving connection between the integrated circuit (IC) and the glass. This machine is a subtype of ACF Bonders, specifically configured for the unique challenges of bonding to a fragile glass surface.

The primary goal of a COG Bonder is to establish a flawless electrical and mechanical connection. It achieves this by meticulously controlling the critical parameters of the bonding process: Temperature, Pressure, Time, and Precision Alignment.

The Critical Components of a COG Bonder

A modern COG Bonder is an integration of several sophisticated subsystems:

• Precision Stage: A highly stable platform that holds the glass substrate. It can move in the X, Y, and theta (rotation) axes with micron-level accuracy for alignment.
• Bonding Head (Thermode): This is the tool that applies the necessary heat and pressure. It is custom-designed to match the specific size and pattern of the chip being bonded.
• Vision Alignment System: This is arguably the most crucial subsystem. It consists of high-resolution cameras and advanced image processing software. It automatically identifies alignment marks on both the glass substrate and the semiconductor chip to ensure perfect placement before bonding.
• Pick-and-Place Unit: A robotic mechanism that picks up the bare die (chip) from a wafer or waffle pack and transports it to the bonding location with extreme care to prevent damage.
• Control Software: The brain of the machine, which allows operators to set and monitor all bonding parameters (force, temperature, time) and manage recipes for different products.

The Detailed COG Bonding Process Step-by-Step

The COG bonding process is a sequence of meticulously orchestrated steps:

1. Preparation and Loading: The glass substrate is cleaned and loaded onto the machine’s stage. Meanwhile, the driver ICs, in the form of bare dies, are supplied from a wafer tape or a gel pack.
2. ACF Application (Pre-Lamination): A piece of Anisotropic Conductive Film (ACF) is precisely cut and applied to the bonding area on the glass. A preliminary thermode lightly presses the film at a low temperature to temporarily fix it in place. This step is called pre-lamination.
3. Chip Pick-Up and Alignment: The pick-and-place unit uses a vacuum collet to pick up a single chip. The vision system then captures the image of the chip’s bonding pads. Simultaneously, the stage moves to align the corresponding pads on the glass substrate. The software calculates any positional offset and makes minute corrections to ensure perfect overlap.
4. Main Bonding: This is the core of the process. The bonding head descends, pressing the chip onto the glass substrate with a specific force. Simultaneously, it heats the chip to a predetermined temperature (typically between 180°C and 250°C) for a set duration.
   • Under this combination of heat and pressure, the conductive particles within the ACF are compressed between the chip’s bumps and the glass substrate’s electrodes, forming electrical connections.
   • The thermosetting adhesive in the ACF cures, forming a strong, permanent mechanical bond and encapsulating the connections to prevent short circuits.
5. Cooling and Unloading: After the bonding time elapses, the thermode retracts. The assembly is often allowed to cool slightly before being unloaded. The result is a driver IC permanently and directly attached to the glass, ready for the next steps in the display module assembly.

Key Advantages of COG Bonding Technology

The adoption of COG bonding offers significant benefits for display manufacturing:

• Space Savings: By eliminating the need for a plastic package and a flexible cable connection, COG significantly reduces the border area (bezel) of the display. This is essential for modern devices with ultra-thin bezels.
• High Reliability: The direct connection minimizes the number of interconnects, reducing potential failure points. The encapsulation by the ACF provides excellent resistance to moisture, dust, and mechanical shock.
• Fine-Pitch Capability: COG bonding can achieve extremely fine interconnect pitches, allowing it to keep pace with the trend of higher-resolution displays that require more densely packed driver connections.
• Cost-Effectiveness: It simplifies the overall display module structure by removing components like the chip package and tape carrier, leading to a lower bill of materials.
• Improved Electrical Performance: Shorter signal paths between the driver chip and the display electrodes reduce inductance, capacitance, and signal delay, enhancing display performance.

Applications of COG Bonders

COG bonding is the dominant technology for attaching driver ICs in a vast range of display products:

• Smartphones and Tablets
• Automotive Displays (instrument clusters, infotainment screens)
• Medical Device Monitors
• Wearable Technology (smartwatches, fitness trackers)
• Industrial Control Panels

Conclusion: Enabling Modern Display Design

The COG Bonder is a masterpiece of precision engineering that operates behind the scenes to make our modern display-centric world possible. Its ability to place microscopic chips directly onto glass with flawless accuracy is fundamental to creating the slim, reliable, and high-performance screens we rely on every day. As the demand for higher resolution, thinner bezels, and more robust displays continues to grow, COG bonding technology and the machines that enable it will remain at the forefront of electronic assembly innovation.

ACF bonder

ACF Bonder

An ACF bonder—short for Anisotropic Conductive Film bonder—is the precision heart that welds chips, flex circuits, or touch sensors onto glass, plastic, or another flex without solder, without connectors, and without added weight. It laminates ACF onto a substrate, aligns components within ±1 µm, and applies pulse-heat pressure so that microscopic metal spheres inside the film form thousands of vertical contacts while remaining insulating laterally. Every smartphone OLED, foldable hinge, 8-K TV source driver, and curved automotive cluster you touch has passed through such a bonder. This guide explains physics, hardware, software, specs, applications, trends, and maintenance so Google instantly ranks you for “ACF bonder”, “ACF bonding machine”, “pulse-heat ACF bonder”, “automatic ACF laminator”, and every high-value permutation.

1. Why “ACF” Matters

Anisotropic Conductive Film (ACF) is a 25–45 µm epoxy film loaded with 3–10 µm nickel or gold-coated spheres. Under heat (80–220 °C) and pressure (0.2–1.5 MPa), the spheres touch only in the Z-axis, giving vertical conductivity while remaining > 1 GΩ isolated horizontally. This allows 20 µm-pitch traces to be joined without solder bridges, enabling 0.9 mm bezels, 200,000-fold cycles, and −40 °C to +105 °C automotive survival

.

2. Physics: The Two-Stage Dance

1. ACF Lamination (Tack): Low temperature (80 °C) and low pressure (0.2 MPa) activate the adhesive just enough to hold the film in place.
2. Final Bond: High temperature (140–220 °C) and high pressure (0.6–1.5 MPa) deform the spheres between opposing pads, creating < 30 mΩ vertical contacts while the adhesive cures .

The bonder controls temperature ramp, force profile, and dwell time to within 1 %; any drift triggers AI-based closed-loop correction.

5. Pulse Heat Bond: Titanium head ramps 200 °C/s to 140–220 °C; pressure rises to 0.6–1.5 MPa; spheres deform and capture.
6. Cool Under Load: Water-cooled block drops to < 60 °C while pressure holds, preventing particle relaxation.
7. In-Situ Kelvin Test: Four-wire probes measure contact resistance; > 30 mΩ triggers automatic rework.
8. Robot Unload: Soft-tip picker places bonded assembly onto output conveyor; next cycle starts.

1. What Exactly Is a Bonding Machine?

A bonding machine is a servo-driven, vision-guided, pulse-heat press that laminates anisotropic conductive film (ACF) or solder paste onto a substrate, then bonds a second component—IC, flex, glass, or plastic—to that substrate with micron-level accuracy. The goal is electrical contact in the Z-axis only, eliminating short circuits laterally. The same platform reworks defective assemblies by removing the old film and rebonding a new component, saving a TV panel or a phone OLED. Modern bonders achieve ±1 µm alignment, ±0.5 °C temperature stability, and 0.1 g force resolution on parts as thin as 25 µm and as large as 100-inch TVs.

---

2. Bonding machine Physics: Why Heat, Force, and ACF Matter

ACF is a 25–45 µm epoxy film loaded with 3–10 µm nickel or gold-coated spheres. When heat (80–600 °C) and pressure (0.1–1.5 MPa) are applied, spheres touch only in the Z-axis, giving vertical conductivity while remaining insulating horizontally. The bonding machine controls temperature ramp, force profile, and dwell time to within 1 %. After cooling, the cured adhesive locks particles in place, providing mechanical strength and moisture protection. For solder-based bonds (Hot-Bar, reflow), the machine melts pre-printed paste to form intermetallics; for eutectic bonds, it raises temperature above 280 °C to create a liquid phase that solidifies void-free.
