Flex Bonding Machine

Flex Bonding Machine

A flex bonding machine—also marketed as a flex cable bonder, FOG bonder, FOB bonder, or FPC bonding machine—is the precision heart that welds flexible printed circuits (FPC) or flexible flat cables (FFC) onto glass, PCB, or another flex using anisotropic conductive film (ACF) and controlled heat plus pressure. Every smartphone OLED, foldable hinge, 8-K TV source driver, and curved automotive cluster you touch has passed through such a platform. This guide explains physics, hardware, software, specs, applications, trends, and maintenance for “flex bonding machine”, “flex cable bonder”, “FOG bonding machine”, “FOB bonding machine”, “FPC bonding machine”, and every high-value permutation.


1. Why “Flex Bonding” Matters in Modern Electronics

Traditional rigid PCBs cannot fold; connectors add height and cost; solder joints fatigue. Flex bonding marries the flexibility of copper-clad polyimide with the reliability of particle-based conductive adhesive, enabling:

  • 0.9 mm bezels (FOG)
  • 200,000-fold cycles at 0.2 mm radius (FOF)
  • −40 °C to +105 °C automotive survival (FOB)
  • Lead-free, repair-friendly joints

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


2. Physics: The Two-Stage Dance (All Flex Modes)

  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: Controlled temperature (140–220 °C) and pressure (0.6–1.5 MPa) deform nickel or gold-coated spheres between opposing pads, creating < 30 mΩ vertical contacts while remaining > 1 GΩ isolated horizontally .

3. Step-by-Step Semi-Automatic Workflow (Generic Multi-Mode)

  1. Operator Load: Places 1–55 in LCD/TFT/OLED or FPC onto vacuum chuck; barcode scanner confirms product ID.
  2. Atmospheric Plasma Cleaning: Raises surface energy to > 60 dynes for ACF wetting.
  3. ACF Lamination: Operator presses “Start”; machine cuts 1–3 mm ACF strip and tacks it at 80 °C, 0.2 MPa.
  4. Semi Vision Alignment: Operator jogs chip/flex under live 12 MP camera; AI calculates X, Y, θ; one-button lock achieves ±0.003 mm .

    • FOF (Flex-On-Flex): 140–180 °C, 0.6–1.0 MPa, ~2 s
    • TFOG/TFOF: same as FOG/FOF
  6. Operator Unload: Removes bonded assembly; next cycle starts.

Cycle time: 6–10 s (operator dependent), throughput: 600–3,000 UPH .

Constant Temperature Bonding Machine

Constant Temperature Bonding Machine

Constant Temperature Bonding Machine

A constant temperature bonding machine—often marketed as a constant heat bonder, constant temperature ACF press, or thermal bonding unit—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 maintains a stable set-point temperature (typically 80–220 °C) for a defined dwell time, allowing anisotropic conductive film (ACF) or thermoplastic adhesive to cure uniformly. Every smartphone OLED, foldable hinge, 8-K TV source driver, and curved automotive cluster you touch has passed through such a machine. This guide explains physics, hardware, software, specs, applications, trends, and maintenance so Google instantly ranks you for “constant temperature bonding machine”, “constant heat bonder”, “constant temperature ACF press”, and every high-value permutation.


1. Why “Constant Temperature” Matters in Modern Electronics

Traditional pulse-heat systems ramp and cool rapidly, which can over-cook adjacent components or cause thermal shock. A constant temperature bonding machine holds a stable set-point (±0.5 °C) for a defined dwell (1–10 s), ensuring:

  • Uniform curing across large-area ACF or thermoplastic films
  • Low thermal shock to adjacent LCD, OLED, or PET substrates
  • Repeatable mechanical properties (shear strength, peel force)
  • Energy efficiency: heater stays at set-point, no ramp waste

The result is a cold-to-cold cycle in < 10 s with ±0.5 °C accuracy, zero overshoot, and no thermal stress on adjacent components.


2. Physics: The Constant-Temperature Cure Cycle

  1. Pressurise: Servo or pneumatic ram lowers the hot-bar onto the work-piece; force is measured by a load cell in real time (0.1 N resolution).
  2. Constant Temperature Hold: Heater chip (titanium or molybdenum) is held at set-point (e.g., 180 °C) for a defined dwell (1–10 s); PID feedback from an embedded K-type thermocouple modulates current to maintain ±0.5 °C.
  3. Cool Under Load: Forced water or ambient air removes heat while pressure is maintained; ACF cures, thermoplastic flows, and the bar lifts only after < 60 °C is reached.

Because the bar is local and line-contact, peripheral components on the LCD/TFT/OLED panel see < 80 °C—ideal for narrow-pitch OLED drivers or PET-based foldable displays.


3. Step-by-Step Fully Automatic Workflow (Constant Temperature)

  1. Robot Loading: 6-axis arm feeds glass, flex, or plastic reel; barcode scanner confirms product ID.
  2. Atmospheric Plasma Cleaning: Raises surface energy to > 60 dynes for ACF wetting.
  3. ACF Lamination: Precision cutter feeds 1–3 mm strip; heated roller tacks film at 80 °C, 0.2 MPa.
  4. AI Vision Alignment: Dual 12 MP cameras capture fiducials; deep-learning algorithm calculates offset in X, Y, θ, and scale within ±1 µm @ 3σ in < 200 ms .
  5. Constant Temperature Bond:
    • Set-point: 80–220 °C (programmable)
    • Dwell: 1–10 s at ±0.5 °C
    • Cool: Forced water or ambient air to < 60 °C while pressure holds
  6. In-Situ Kelvin Test: Four-wire probes measure contact resistance; > 30 mΩ triggers automatic rework.
  7. Robot Unload: Soft-tip picker places bonded assembly onto output conveyor; next cycle starts.

Pulse Heat Bonding Machine

Pulse Heat Bonding Machine

A pulse heat bonding machine—often marketed as a pulse heat bonder, Hot-Bar bonder, or ACF pulse heat press—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 uses controlled heat and pressure to deform microscopic conductive particles inside anisotropic conductive film (ACF), creating thousands of vertical contacts in under three seconds while keeping lateral isolation > 1 GΩ. Every smartphone OLED, foldable hinge, 8-K TV source driver, and curved automotive cluster you touch has passed through such a machine. This guide explains physics, hardware, software, specs, applications, trends, and maintenance for “pulse heat bonding machine”, “pulse heat bonder”, “Hot-Bar bonding machine”, “ACF pulse heat press”, and every high-value permutation.


1. Why “Pulse Heat” Matters in Modern Electronics

Traditional constant-heat presses waste energy and over-cook surrounding components. A pulse heat bonder delivers instantaneous resistance heat through a titanium or molybdenum heater chip (Hot-Bar). The current is pulsed ON/OFF at kilohertz frequency, so:

  • Rise time: 200 °C/s to target (e.g., 180 °C) in < 1 s
  • Dwell: programmable plateau (e.g., 2 s)
  • Cool-down: forced water or ambient air to < 60 °C while pressure is maintained

The result is a cold-to-cold cycle in < 5 s with ±0.5 °C accuracy, zero overshoot, and no thermal stress on adjacent LCD, OLED, or PET substrates.


2. Physics: The Three-Stage Pulse Heat Cycle

  1. Pressurise: Servo or pneumatic ram lowers the Hot-Bar onto the work-piece; force is measured by a load cell in real time (0.1 g resolution).
  2. Pulse Heat: Low-voltage, high-current pulses (typ. 5 V, 800 A) flow through the bar; PID feedback from an embedded K-type thermocouple modulates pulse width to follow the exact profile (pre-heat, main-heat, reflow).
  3. Cool Under Load: Water-cooled block or ambient air removes heat while pressure is maintained; particles solidify, ACF cures, and the bar lifts only after < 60 °C is reached.

Because the bar is local and line-contact, peripheral components on the LCD/TFT/OLED panel see < 80 °C—ideal for narrow-pitch OLED drivers or PET-based foldable displays.


3. Step-by-Step Fully Automatic Workflow

  1. Robot Loading: 6-axis arm feeds glass, flex, or plastic reel; barcode scanner confirms product ID.
  2. Atmospheric Plasma Cleaning: Raises surface energy to > 60 dynes for ACF wetting.
  3. ACF Lamination: Precision cutter feeds 1–3 mm strip; heated roller tacks film at 80 °C, 0.2 MPa.
  4. AI Vision Alignment: Dual 12 MP cameras capture fiducials; deep-learning algorithm calculates offset in X, Y, θ, and scale within ±1 µm @ 3σ in < 200 ms .
  5. Pulse Heat Bond:
    • Rise: 200 °C/s to 160–220 °C (programmable)
    • Dwell: 1–3 s at ±0.5 °C
    • Cool: Forced water or ambient air to < 60 °C while pressure holds
  6. In-Situ Kelvin Test: Four-wire probes measure contact resistance; > 30 mΩ triggers automatic rework.
  7. Robot Unload: Soft-tip picker places bonded assembly onto output conveyor; next cycle starts.

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

An ACF/COG/COP/COF/FOG/FOB/FOF/TFOG/TFOF /OLB/TAB Bonding Machine is the universal welder of modern electronics. It laminates anisotropic conductive film (ACF) and then bonds chips, flex circuits, or touch sensors onto glass, plastic, or another flex—without solder, without connectors, and without added weight. Whether you need vertical conductivity between a gold-bumped IC and an ITO panel, or a foldable flex tail that survives 200,000 bends, this multi-acronym platform delivers micron alignment, single-degree thermal control, and kilogram-level force in under three seconds. This guide explains every process, physics, hardware, software, spec, application, trend, and maintenance tip so Google instantly ranks you for “ACF bonding machine”, “COG bonder”, “COP bonding machine”, “COF bonder”, “FOG bonder”, “FOB bonding machine”, “FOF bonding machine”, “TFOG bonder”, “TFOF bonding machine”, “OLB bonding machine”, “TAB bonder”, and every high-value permutation.


1. Why “Multi-Acronym” Matters in Modern Electronics

Each letter pair describes a different “X-on-Y” marriage:

  • ACF – Anisotropic Conductive Film (the common adhesive)
  • COG – Chip-On-Glass
  • COP – Chip-On-Plastic (foldable PET/PI)
  • COF – Chip-On-Film (reel-fed copper tail)
  • FOG – Flex-On-Glass
  • FOB – Flex-On-Board (PCB)
  • FOF – Flex-On-Flex
  • TFOG – Touch-Flex-On-Glass
  • TFOF – Touch-Flex-On-Film
  • OLB – Outer Lead Bonding (generic term for tail-to-glass)
  • TAB – Tape Automated Bonding (historic term for copper-on-pilm reel)

A single granite-based machine swaps jigs and recipes in < 15 s to cover all variants, sharing the same AI vision, servo force, and cloud dashboard.


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: Controlled temperature (140–220 °C) and pressure (0.6–1.5 MPa) deform nickel or gold-coated spheres between opposing pads, creating < 30 mΩ vertical contacts while remaining > 1 GΩ isolated horizontally .

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

  4. AI Vision Alignment: Dual 12 MP cameras capture fiducials; deep-learning algorithm calculates offset in X, Y, θ, and scale within ±1 µm @ 3σ in < 200 ms .
  5. Controlled Bond:
    • COG/COP/COF: 160–220 °C, 0.8–1.5 MPa, ~2 s
    • FOG/FOB/FOF/TFOG/TFOF: 140–200 °C, 0.6–1.2 MPa, ~2 s
    • OLB/TAB: same as FOG
  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.

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.


4. Step-by-Step Fully Automatic Workflow

  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.

5. Core Hardware That Determines Performance

Granite Base: 0.05 µm linear encoder, 20 kHz servo loop, passive vibration isolation.
Bonding Head: Titanium alloy, diamond-lapped to 0.3 µm flatness, DLC-coated for anti-stick, 300,000-cycle life .

OLB Bonder

OLB Bonder

OLB Bonder

An OLB bonder—short for Outer Lead Bonder—is the precision heart that welds the “outer” copper leads of a COF (Chip-On-Film) or TAB (Tape Automated Bonding) tail onto a glass panel, PCB, or flexible substrate using anisotropic conductive film (ACF) and controlled heat plus pressure. Inside every 8-K TV, curved automotive cluster, or foldable phone you see today, an OLB 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 “OLB bonder”, “OLB bonding machine”, “automatic OLB bonder”, “ACF OLB bonding”, and every high-value permutation.


1. Why “OLB” 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. OLB moves the IC onto a flexible polyimide tail (COF) that can dissipate heat, fold 180°, and be replaced during repair. The OLB bonder is the machine that welds that tail’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 an OLB Bonder?

An OLB 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 COF/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 tail.
  • 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.


4. Step-by-Step Fully Automatic Workflow

  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.

5. Core Hardware That Determines Performance

Granite Base: 0.05 µm linear encoder, 20 kHz servo loop, passive vibration isolation.
Bonding Head: Titanium alloy, diamond-lapped to 0.3 µm flatness, DLC-coated for anti-stick, 300,000-cycle life .

Semi-Automatic Bonding Machine

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.


3. Step-by-Step Fully Automatic Workflow

  1. Reel Loading: Robot loads 8–70 mm polyimide reel; dancer-arm tension control maintains < 0.5 N fluctuation.
  2. Atmospheric Plasma Cleaning: Raises surface energy to > 60 dynes for ACF wetting.
  3. ACF Lamination: Precision cutter feeds 1–3 mm strip; heated roller tacks film to plastic at 80 °C, 0.2 MPa.
  4. IC Pick-Up: Vacuum collet lifts die from waffle pack; soft-tip ejector prevents silicon cratering.
  5. AI Vision Alignment: Dual 12 MP cameras capture fiducials on bumps and copper leads; deep-learning algorithm calculates offset in X, Y, θ, and scale within ±1 µm @ 3σ in < 200 ms.
  6. Pre-Bond: Head descends at 60 °C and 0.1 MPa to tack the IC; system verifies overlap ≥ 98 %.
  7. Pulse Heat Bond: Titanium head ramps 200 °C/s to 140–180 °C; pressure rises to 0.6–1.0 MPa; spheres deform and capture.
  8. Cool Under Load: Water-cooled block drops to < 60 °C while pressure holds, preventing particle relaxation.
  9. Fold Test (Optional): Mandrel bends plastic 180° with 0.2 mm radius; vision checks for trace cracking or whitening.
