Fully Automatic COG COF COP FOG FOB FOF TFOG Bonding Machine

ACF COG COP COF FOG FOB FOF TFOG TFOF OLB TAB Bonding Machine

ACF COG COP COF FOG FOB FOF TFOG TFOF OLB TAB Bonding Machine

Modern displays, sensors, and wearables are born on the factory floor through a family of “X-on-Y” bonds. Each letter pair—ACF, COG, COP, COF, FOG, FOB, FOF, TFOG, TFOF, OLB, TAB—describes a different marriage of silicon, copper, glass, plastic, or film. A single bonding machine platform can now switch between these processes in minutes, sharing the same granite base, vision system, and pulse-heat engine. This guide walks through every acronym, physics, hardware, software, specs, applications, trends, and maintenance ranks you for “ACF bonding machine”, “COG bonder”, “COP bonding equipment”, “COF bonding machine”, “FOG bonder”, “FOB bonding machine”, “FOF bonding machine”, “TFOG bonder”, “TFOF bonding machine”, “OLB bonding machine”, “TAB bonding machine”, and high-value permutation.

1. ACF: The Common Glue Behind Every Bond

Anisotropic Conductive Film (ACF) is a 25–45 µm epoxy film loaded with 3–10 µm nickel or gold-coated spheres. When heat (80–220 °C) and pressure (0.2–1.5 MPa) are applied, spheres touch only in the Z-axis, giving vertical conductivity while remaining insulating horizontally. ACF is laminated first; the specific “X-on-Y” step follows. Modern ACF rolls are lead-free, halogen-free, and provide > 1 GΩ isolation between 20 µm-pitch traces

  • TFOG – Touch-Flex-On-Glass: capacitive-touch sensor tail bonded to cover glass; 160–200 °C, survives 200 k bends.
  • TFOF – Touch-Flex-On-Film: touch sensor tail to plastic substrate; transparent PET, 120 °C bond.
  • OLB – Outer Lead Bonding: generic term for bonding the “outer” leads of a TAB/COF tail to glass or PCB; often used interchangeably with FOG/FOB.
  • TAB – Tape Automated Bonding: historic term for copper leads on a polyimide carrier; today synonymous with COF reels.

3. Shared Hardware Core Across All Variants

A modern multi-mode bonding machine uses the same granite base, 0.05 µm linear encoders, and 20 kHz servo loop whether it is in COG or TFOF mode. The head is titanium, DLC-coated, lapped to 0.3 µm flatness. An 800 W pulse heater ramps 200 °C/s with ±0.5 °C stability. Vision is dual 12 MP CMOS, telecentric, repeatable to 0.2 µm. Force is voice-coil driven, 0.1 N resolution, 2 ms response. ACF is cut by tungsten blades and tacked at 80 °C, 0.2 MPa. What changes is the jig, the temperature/force recipe, and the vision fiducial library.

TFOG Bonding Machine

TFOG Bonding Machine – Touch Flex-On-Glass

A T-FOG bonding machine (Touch-Flex-On-Glass) is the micron-precision link that welds the capacitive-touch sensor tail directly to the cover glass or sensor glass of a display module. In every smartphone, tablet, curved automotive cluster, or wearable OLED you touch today, a T-FOG bonder has aligned ITO or metal-mesh touch pads to copper leads within ±1 µm and created thousands of vertical contacts in under three seconds. This article explains physics, hardware, software, specs, applications, trends, and maintenance for “T-FOG bonding machine”, “Touch-Flex-On-Glass bonder”, “touch sensor ACF bonding”, “capacitive touch flex bonding”, “OLED T-FOG bonding”

1. What Exactly Is T-FOG Bonding?

T-FOG stands for Touch-Flex-On-Glass. The capacitive touch layer of a modern display is a separate flex circuit (often with its own controller IC) that must be electrically connected to the cover glass or sensor glass. The flex tail carries fine copper traces that fan out to ITO or metal-mesh touch pads on the glass. A T-FOG bonding machine laminates anisotropic conductive film (ACF) onto the glass, aligns the touch-flex pads to the glass pads within micron accuracy, and executes a pulse-heat bond at 160–200 °C and 0.8–1.5 MPa. Conductive particles trapped between copper and ITO form < 30 mΩ contacts vertically while remaining > 1 GΩ isolated horizontally. After the bond, the tail is folded 180° so the controller IC hides behind the glass, shrinking the bezel to under 1 mm.

2. Why T-FOG Still Dominates Touch Modules

COG (Chip-On-Glass) places the touch controller directly on the glass, but large 8-K OLED panels generate too much heat—T-FOG moves the IC onto a flex tail that can dissipate heat and be replaced during repair. Connector solutions add 0.3 mm height and cost $0.50; T-FOG adds 0.03 mm and costs <$0.05. Automotive Tier-1 suppliers prefer T-FOG because it passes AEC-Q100 Grade 0 (−40 °C to +150 °C) without a single connector contact.

3. Step-by-Step Working Principle

  2. ACF Lamination: Precision cutter feeds 1–3 mm ACF strip; heated roller (80 °C, 0.2 MPa) tacks film to glass ITO pads.
  3. Flex Placement: Robot places touch-flex tail; vacuum chuck holds glass flat.
  4. Vision Alignment: Dual 12 MP cameras capture fiducials on flex pads and glass ITO; AI algorithm calculates offset in X, Y, θ, and scale.
  5. Pre-Bond: Head descends at 60 °C and 0.1 MPa to tack the flex; system verifies overlap ≥ 98 %.
  6. Pulse Heat Bond: Titanium head ramps to 160–200 °C in 1.5 s; pressure rises to 1.0 MPa; conductive particles deform and capture.
  7. Cool Under Load: Water-cooled block drops temperature below 60 °C while pressure holds, preventing particle relaxation.

FOF BONDING MACHINE

FOF Bonding Machine

FOF Bonding Machine

A FOF bonding machine—short for Flex-On-Flex or Film-On-Film—is the precision heart that folds one floppy polyimide tail onto another and welds them into a single, ultra-reliable flexible circuit. Inside foldable phones, medical catheters, curved automotive clusters, and next-generation wearable patches, two flexible printed circuits (FPCs) must be joined without rigid boards, bulky connectors, or solder joints that fatigue. The FOF bonder grabs the top flex, aligns it to the bottom flex within ±1 µm, and compresses anisotropic conductive film (ACF) between their copper pads. A 1.5-second pulse of 180 °C and 1 MPa deforms thousands of gold-coated spheres inside the film, creating vertical contacts while keeping lateral isolation. Water-cooling locks the particles in place; the whole cycle finishes in 2.8 seconds.

1. Why FOF Bonding Surges

Foldable phones need a hinge area that bends 200,000 times at 0.2 mm radius—rigid PCB would crack. Automotive cameras must fold sensor tails behind 3D-shaped plastic housings that see −40 °C to +105 °C. Medical catheters require transparent, sterilizable PET layers that survive autoclave steam without delamination. FOF solves these pain points by marrying the flexibility of copper-clad polyimide with the reliability of particle-based conductive adhesive, all while enabling repair: a defective flex can be removed and rebonded without scrapping the entire $300 assembly.

2. Step-by-Step Working Principle

  1. Surface Preparation: Both top and bottom flexes are cleaned with ionized air and isopropyl alcohol to remove mold-release agents and oxide.
  2. Plasma Activation (Optional): Atmospheric plasma raises surface energy of polyimide to > 60 dynes, ensuring ACF wetting on low-energy polymers.
  3. ACF Lamination: Precision cutter feeds 1–3 mm ACF strip; heated roller (80 °C, 0.2 MPa) tacks film to the bottom flex pads.
  4. Vision Alignment: Dual 12 MP cameras capture fiducials on both flexes; AI algorithm calculates offset in X, Y, θ, and scale.
  5. Pre-Bond: Head descends at 60 °C and 0.1 MPa to tack the top flex; system verifies pad-to-pad overlap ≥ 98 %.
  6. Pulse Heat Bond: Titanium head ramps to 160–200 °C in 1.5 s; pressure rises to 1.0 MPa; conductive particles deform and capture.
  7. Cool Under Load: Water-cooled block drops temperature below 60 °C while pressure holds, preventing particle relaxation.
  8. In-Situ Test: Four-wire Kelvin probes measure contact resistance per trace; values > 30 mΩ trigger automatic rework.
  9. Fold Test (Optional): Mandrel folds the joint 180° with 0.2 mm radius; vision checks for trace cracking or coverlay whitening.

FOP bonding machine

FOP Bonding Machine

FOP Bonding Machine

FOP Bonding Machine

A FOP bonding machine—short for Flex-On-Plastic or Film-On-Plastic—is the precision heart that folds a floppy polyimide tail onto a rigid or semi-rigid plastic substrate and welds it there with micron accuracy. The process is driven by anisotropic conductive film (ACF), heat, and force, creating thousands of vertical contacts while keeping lateral insulation. The result is a vibration-proof, chemical-resistant, lead-free joint that survives −40 °C automotive winters, +105 °C engine-bay summers, and 95 % humidity in medical sterilizers. This article explains every angle of the technology for “FOP bonding machine”, “FOP bonder”, “flex-on-plastic bonding”, “ACF FOP machine”, “automotive FOP bonding”, “medical FOP bonding” high-value keywords.

1. What a FOP Bonding Machine Really Is

A FOP bonding machine is a servo-driven, vision-guided, pulse-heat press that laminates anisotropic conductive film onto a plastic substrate—typically PET, PEN, PI, or LCP—and then bonds a flexible printed circuit (FPC) or chip-on-film (COF) tail to that plastic with sub-micron accuracy. The film contains nickel or gold-coated spheres that conduct only vertically, giving thousands of simultaneous contacts while remaining insulating laterally. The same platform reworks defective assemblies by removing the old ACF and rebonding a new tail, saving automotive sensor or disposable medical catheter.

2. Why FOP Is Surging

Metal chassis are heavy; glass is brittle; FR-4 is thick. Automotive designers want 3D-shaped, lightweight, chemical-resistant plastic dashboards. Medical OEMs need transparent, sterilizable PET circuits that survive autoclave cycles. Consumer brands chase foldable phones with plastic mid-plates that bend 180°. FOP solves these pain points by marrying the flexibility of copper-clad polyimide with the moldability of engineering plastics, all while enabling repair: a defective flex can be removed and rebonded without scrapping the entire plastic assembly.

OLB bonding machine

OLB Bonding Machine

OLB Bonding Machine

An OLB bonding machine is the hidden hero behind every large-screen TV, laptop and automotive display you see today. OLB—Outer Lead Bonding—is the final assembly step in which the “outer leads” of a TAB (Tape Automated Bonding) or COF (Chip-On-Film) package are attached to a glass panel or PCB so that signals from the driver IC can reach the outside world. The equipment that performs this micro-weld must deliver sub-micron alignment, single-degree thermal control and kilogram-level force accuracy—all in under three seconds. This article explains every angle of the technology for “OLB bonding machine”, “OLB bonder”, “outer lead bonding equipment”, “TAB OLB bonding”, “COF OLB bonding”, “LCD OLB repair machine” and dozens more high-value keywords.

1. What Exactly Is OLB?

OLB is the acronym for “Outer Lead Bonding”. In a display module the driver IC is first mounted on a flexible polyimide tape (TAB) or on a continuous reel (COF). The inner leads of that tape are bonded to the IC bumps in an earlier process called ILB (Inner Lead Bonding). The outer leads—fine copper traces that fan out beyond the IC—must now be connected to the display glass (for source drivers) or to a rigid PCB (for gate drivers). The machine that executes this final link is called an OLB bonding machine. It uses anisotropic conductive film (ACF) to create thousands of vertical contacts while remaining insulating laterally, then folds the tail 180° so the IC disappears behind the panel, shrinking the bezel to under 1 mm.

2. Why OLB Still Dominates Large-Size Displays

COG (Chip-On-Glass) works well for phones, but for 32″-120″ TVs the driver ICs generate too much heat to be parked on the glass. COF (Chip-On-Film) brings the IC onto a flex tail, but the tail must still exit sideways before folding—OLB is the step that actually welds that tail to the glass or PCB. The process is repair-friendly: a defective tail can be removed and rebonded without scrapping the entire panel. Automotive Tier-1 suppliers also rely on OLB because it survives 1,000 h of 85 °C/85 % RH and −40 °C to +105 °C thermal cycling required

3. Step-by-Step Working Principle

  1. Plasma Cleaning: Atmospheric plasma removes organic contamination and raises surface energy to > 60 dynes for ACF wetting.
  2. ACF Lamination: Precision cutter feeds 1–3 mm ACF strip; heated roller (80 °C, 0.2 MPa) tacks film to the glass or PCB pads.
  3. Vision Alignment: Dual 12 MP cameras capture fiducials on the TAB/COF tail and on the substrate; AI algorithm calculates offset in X, Y, θ, and scale.
  4. Pre-Bond: Head descends at 60 °C and 0.1 MPa to tack the tail; system verifies pad-to-pad overlap ≥ 98 %.
  5. Pulse Heat Bond: Titanium head ramps to 180–220 °C in 1.5 s; pressure rises to 1.0 MPa; conductive particles deform and capture.
  6. Cool Under Load: Water-cooled block drops temperature below 60 °C while pressure holds, preventing particle relaxation.
  7. In-Situ Test: Four-wire Kelvin probes measure contact resistance per trace; values > 30 mΩ trigger automatic rework.
  8. Fold Test (Optional): Mandrel folds the tail 180° with 0.2 mm radius; vision checks for trace cracking.

4. Core Hardware That Determines Performance

FOB Bonding Machine

FOB Bonding Machine

A FOB bonding machine—short for Flex-On-Board or Film-On-Board—is the critical link between a floppy polyimide tail and a rigid printed-circuit board. It grabs a flexible printed circuit (FPC), aligns it to a PCB within a single micron, and welds the copper traces together with anisotropic conductive film (ACF) in under three seconds. The result is a vibration-proof, heat-proof, lead-free joint that survives −40 °C automotive winters and +105 °C engine-bay summers. This guide walks through physics, hardware, software, specs, applications, trends, and maintenance rank you for “FOB bonding machine”, “FOB bonder”, “FPC to PCB bonding”, “ACF FOB machine”, “automotive FOB bonding”,

1. What a FOB Bonding Machine Really Is

A FOB bonding machine is a servo-driven, vision-guided, pulse-heat press that laminates anisotropic conductive film onto a PCB, then bonds a flexible printed circuit (FPC) or chip-on-film (COF) tail to that PCB with micron-level accuracy. The film contains nickel or gold-coated spheres that conduct only vertically, giving thousands of simultaneous contacts while remaining insulated laterally. The same platform reworks defective boards by removing the old ACF and rebonding a new tail, saving a $200 automotive cluster or a $150 tablet mainboard.

2. Why FOB Still Dominates

Rigid PCBs cannot fold; wire harnesses fail after 10,000 vibration cycles; connectors add height and cost. FOB eliminates all three pain points by folding a 25 µm polyimide tail 180° with 0.2 mm radius and locking it to the PCB in a 2-second cycle. Automotive Tier-1 suppliers prefer FOB because it passes AEC-Q100 Grade 0 (−40 °C to +150 °C) without a single connector contact. Consumer OEMs love the 0.9 mm board-edge profile that enables edge-to-edge displays.

IC Bonding Machine

IC Bonding Machine

An IC bonding machine is the beating heart of every microelectronic package you touch—whether it’s the OLED display in your foldable phone, the radar sensor in your car, or the memory stack in your laptop. It is the precision system that places a bare silicon die onto a substrate—glass, flex, PCB, or lead-frame—and then creates permanent electrical joints by thermo-compression, ultrasonic, or eutectic means. Keywords”IC bonding machine”, “IC die bonder”, “wire bonding machine”, “eutectic IC bonder”, “flip-chip bonder”, “COG bonding machine”, “COB bonding machine”, “thermosonic bonding”, “ultrasonic wire bonder.

1. What Exactly Is an IC Bonding Machine?

An IC bonding machine is a high-precision mechatronic platform that picks up a bare integrated-circuit die from a wafer, waffle pack, or gel-pak, places it with micron accuracy onto a target substrate, and then forms electrical and mechanical joints by one of three core methods: wire bonding (thermosonic or ultrasonic), flip-chip thermo-compression, or eutectic/solder reflow. Modern platforms achieve ±1 µm placement accuracy, ±0.3 ° angular repeatability, and 0.1 g force resolution on die sizes from 0.25 mm × 0.25 mm to 25 mm × 25 mm. The same machine also reworks defective packages by removing the old die and rebonding a new one.

2. Physics Behind the Bond: Why Heat, Force, and Ultrasound Matter

Gold or copper bumps on the die must touch copper pads on the substrate. At room temperature the native oxide layer prevents reliable contact. Thermosonic wire bonding uses 150 °C stage heat plus 60 kHz ultrasonic energy to break the oxide and form Au-Al intermetallics. Flip-chip thermo-compression applies 200 °C and 1 MPa to deform gold or solder bumps, creating cold-weld joints. Eutectic bonding raises temperature above 280 °C so Au-Sn or Cu-Sn forms a liquid phase that solidifies into a void-free joint. Each method demands closed-loop temperature, force, and time control to within 1 %.

3. Step-by-Step Working Principle (Wire-Bond Example)

  1. Wafer Mapping: Machine vision scans the wafer, records good-die coordinates, and skips inked or cracked units.
  2. Die Pick-Up: Ejector needles push the die upward while a vacuum collet grips it; force is kept below 50 g to avoid silicon cratering.
  3. Die Placement: Linear motor moves the die over the substrate; bottom camera aligns fiducials; placement accuracy ±1 µm @ 3σ.
  4. First Bond (Ball Bond): Capillary descends, forms a free-air ball, scrubs at 60 kHz, 40 g force, 150 °C for 15 ms.
  5. Loop Formation: Capillary traces a controlled loop height (50–500 µm) to avoid shorting adjacent wires.
  6. Second Bond (Wedge Bond): Capillary stitches the wire to the substrate pad, breaks the tail, and feeds fresh wire for the next cycle.
  7. In-Situ Inspection: High-speed camera checks ball shape, loop height, and tail length; AI flags outliers for rework.

4. Core Hardware Modules That Determine Performance

Die Bond Head: Ceramic or titanium collet, 0.1 µm run-out, vacuum channel optimized for 50 µm thin die.

FPC Bonding Machine

FPC Bonding Machine

An FPC bonding machine is the silent enabler behind every foldable phone, curved smart-watch, 4K laptop, and automotive cluster you touch today. FPC—Flexible Printed Circuit—must be joined to glass, PCB, or another flex with micron accuracy, vertical conductivity, and horizontal insulation. The equipment that delivers this marriage is a servo-driven, vision-guided, constand temperature and pulse-heat press called an FPC bonding machine. Keywords “FPC bonding machine”, “FPC to glass bonder”, “ACF FPC bonding”, “flex cable bonding equipment”, “pulse heat FPC machine”

1. What an FPC Bonding Machine Really Is

An FPC bonding machine is a high-precision constatn temperature and pulse-heat press that bonds a flexible printed circuit to a rigid or flexible substrate through anisotropic conductive film (ACF) or solder paste. The bond must conduct electricity vertically between copper pads while remaining insulating laterally, must survive 100,000 bend cycles, and must fit inside a 0.9 mm bezel. Modern machines achieve ±1 µm alignment, ±0.5 °C temperature stability, and 0.01 MPa force resolution on substrates as thin as 25 µm and as large as 100-inch TVs.

2. Why FPC Bonding Still Dominates

Foldable phones need a flex tail that folds 180° with 0.2 mm radius—rigid PCB cannot survive. Automotive clusters require vibration resistance from −40 °C to +105 °C—wire harnesses fail. Medical wearables demand biocompatible polyimide—solder joints crack. FPC bonding solves these pain points by combining the flexibility of copper-clad polyimide with the reliability of particle-based conductive adhesive, all while enabling repair: a defective flex can be removed and rebonded without scrapping the entire OLED assembly.

3. Step-by-Step Working Principle

  1. Surface Preparation: Both FPC and target substrate (glass, PCB, or second flex) are cleaned with ionized air and IPA to remove dust and oxide.
  2. ACF Application: A strip of anisotropic conductive film is cut to length and laminated at 80 °C and 0.2 MPa.
  3. Vision Alignment: Dual 12 MP cameras capture fiducials on FPC and substrate; AI algorithm calculates offset in X, Y, θ, and scale.
  4. Pre-Bond: Head descends at 60 °C and 0.1 MPa to tack the FPC; system verifies pad-to-pad overlap ≥ 98 %.
  5. Main Bond: Pulse heat ramps to 180–200 °C in 1.5 s; pressure rises to 1.0 MPa; conductive particles deform and capture.
  6. Cool Under Load: Water-cooled block drops temperature below 60 °C while pressure holds, preventing particle relaxation.
  7. In-Situ Test: Four-wire Kelvin probes measure contact resistance per trace; values > 30 mΩ trigger automatic rework.
  8. Fold Test (Optional): Mandrel folds tail 180° with 0.2 mm radius; vision checks for trace cracking.

4. Core Hardware That Determines Performance

ACF Bonding Machine

ACF Bonding Machine

An ACF bonding machine is the precision heart of every modern display factory and repair lab.
ACF—Anisotropic Conductive Film—contains microscopic nickel or gold-coated spheres suspended in an adhesive resin.
When heat and pressure are applied, those particles touch only in the Z-axis, giving vertical conductivity while remaining insulating horizontally.
The machine that choreographs this three-second micro-explosion must control temperature within half a degree, pressure within a tenth of a bar, and alignment within a single micron.
High-value keywords.:”ACF bonding machine”, “ACF bonder”, “LCD ACF bonding”, “pulse-heat ACF machine”, “TV panel ACF repair”

1. What Exactly Is an ACF Bonding Machine?

An ACF bonding machine is a servo-controlled pulse-heat press that laminates anisotropic conductive film onto a substrate, then bonds a second component—IC, flex, COF, or glass—using precisely programmed temperature, pressure, and time.
The goal is electrical contact in the vertical direction only, eliminating short circuits laterally.
The same machine also reworks defective panels by removing the old film and rebonding a new piece, saving a $300 TV screen or a $150 phone OLED.
Modern platforms handle 1-inch wearables to 100-inch TVs with ±1 µm alignment, ±0.5 °C thermal stability, and 0.01 MPa force resolution.

2. Physics Behind ACF: Why It Conducts Only Up-and-Down

ACF is a 25–45 µm epoxy film loaded with 3–10 µm conductive spheres—nickel, gold-coated plastic, or copper-silver alloy.
During bonding, heat softens the resin and pressure compresses spheres between opposing pads.
The sphere count per pad is statistically designed so that at least three particles touch, giving < 30 mΩ contact resistance vertically.
Because neighboring pads are 20–50 µm apart, lateral particle density is too low to create a leakage path (> 1 GΩ isolation).
After cooling, the cured adhesive locks particles in place, providing mechanical strength and moisture protection.

3. Step-by-Step Working Principle

  1. Surface Prep: Substrate is cleaned with ionized air and IPA to remove dust and oxide.
  2. ACF Lamination: Precision cutter feeds 1–3 mm strip; heated roller (80 °C, 0.2 MPa) tacks film to glass or flex.
  3. Component Alignment: Dual CCD cameras capture bumps on IC/COF and pads on substrate; AI algorithm calculates offset in X, Y, θ.
  4. Pre-Bond: Head descends at 60 °C and 0.1 MPa to tack component; system verifies overlap ≥ 95 %.
  5. Pulse Heat Bond: Titanium head ramps to 180–220 °C in 1.5 s; pressure rises to 1.0 MPa; particles deform and capture.
  6. Cool Under Load: Water-cooled block drops temperature below 60 °C in 1 s while pressure holds, preventing voids.
  7. In-Situ Test: Four-wire Kelvin measures contact resistance per bump; values > 50 mΩ trigger automatic rework.
  8. Unload & Clean: Ionized air removes debris; panel moves to AOI for visual inspection.

TAB Bonding machine

TAB Bonding Machine

TAB Bonding Machine

A TAB bonding machine is the unsung hero inside every LCD television, laptop, tablet, and industrial monitor you use today. TAB—Tape Automated Bonding—refers to the process of bonding a driver IC mounted on a flexible polyimide tape to a glass or PCB substrate using anisotropic conductive film (ACF). The machine that performs this task must deliver micron-level alignment, single-degree temperature control, and kilogram-level pressure accuracy—all in under four seconds. High-value keywords like “TAB bonding machine”, “LCD TAB bonder”, “ACF TAB bonding”, “TV panel repair machine”, “pulse heat TAB bonding”, and more.

1. What Is a TAB Bonding Machine?

A TAB bonding machine is a high-precision pulse-heat press that bonds a driver IC mounted on a flexible tape to a glass or PCB substrate. The tape contains copper traces and is pre-bumped with gold or tin. ACF is used to create vertical conductivity between the bumps and the substrate while maintaining horizontal insulation. The result is a durable, flexible, and lead-free interconnect that survives thermal cycling, mechanical stress, and humidity. TAB bonding is widely used in LCD, LED, OLED, and QLED displays ranging from 5-inch smartphones to 100-inch TVs.

2. Why TAB Still Matters

Although COG (Chip-On-Glass) and COF (Chip-On-Film) have gained popularity, TAB remains the go-to solution for large-size panels and repair markets. TAB allows the IC to be tested and burned-in before bonding, improving yield. The flexible tape absorbs thermal expansion mismatch between the IC and glass, enhancing reliability. TAB also enables repair: a defective IC can be removed and a new one bonded without scrapping the entire panel, saving hundreds of dollars per screen.
