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

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

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

Pre-Bond: Head descends at 60 °C and 0.1 MPa to tack component; system verifies overlap ≥ 95 %.

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.

COP Bonding Machine

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.

COG bonding machine — COP BONDING MACHINE

1. What Exactly Is a COP Bonding Machine?

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.

2. Why COP Beats COG and COF in Ultra-Slim Designs

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.

COG bonding machine

A COG bonding machine is the micro-surgical robot of the display world.
COG—Chip-On-Glass—means the bare driver IC is flipped, aligned, and permanently fused directly to the glass substrate of an LCD, OLED, or mini-LED panel.
Because the chip sits on the glass instead of a flexible circuit, bezels shrink, signal paths shorten, and phones, tablets, laptops, TVs, automotive clusters, and medical monitors become thinner, lighter, and more reliable.
High-value keywords: “COG bonding machine”, “Chip on Glass bonder”, “LCD IC bonding equipment”, “ACF COG machine”, “pulse heat COG bonder”, “narrow bezel bonding”, “smartphone display bonding”, “automotive COG bonding”, and many more.

1. What a COG Bonding Machine Really Is

A COG bonding machine is a high-precision pulse-heat press that picks up a gold-bumped driver IC, places it face-down on a glass substrate, and bonds it through anisotropic conductive film (ACF) in one three-second cycle.
The film contains 3–5 µm nickel or gold-coated plastic spheres.
Heat and pressure trap particles between IC bump and glass pad, creating thousands of vertical contacts while remaining insulated laterally.
The result is a permanent, flexible, lead-free interconnect that survives −40 °C to +85 °C thermal shock, 1,000-cycle bend tests, and 95 % humidity at 65 °C for 1,000 h.
Modern COG bonders achieve ±1 µm alignment, ±0.3 °C temperature stability, and 0.1 kg force resolution on panels from 1 inch smartwatches to 17 inch automotive displays.

2. Why COG Still Beats COF or COB in Many Designs

COG eliminates the flexible printed circuit entirely.
Signal length from IC to pixel column drops 50 %, reducing EMI at 120 Hz and 240 Hz refresh rates.
Because the IC overhangs only 0.3 mm beyond the active area, bezels shrink to 0.9 mm, enabling edge-to-edge smartphones and seamless multi-screen video walls.
Cost drops: no flex, no connector, less copper.
Yield rises: fewer solder joints, no FPC misalignment.
Rework is possible: a laser can remove a defective IC and rebond a new one in under two minutes

3. Step-by-Step Working Principle

Pre-Bond: Head descends to 50 °C and 0.1 MPa to tack the IC; machine verifies bump-to-pad overlap ≥ 90 %.
Main Bond: Pulse heat ramps to 180–220 °C in 1.5 s; pressure climbs to 1.0–1.5 MPa; particles deform and capture; thermocouple closes loop at 1 kHz.
Cool Under Load: Water-cooled block drops temperature below 60 °C in 1 s while pressure holds, preventing voids.

COF Bonding Machine

A COF bonding machine is the quiet hero inside every ultra-slim TV, foldable phone, and curved automotive cluster. COF means Chip-On-Film: a bare driver IC is bumped, flipped, and bonded to a thin polyimide ribbon that later folds tightly behind the glass. The machine that performs this microscopic wedding must deliver micron-level alignment, single-degree temperature control, and ton-class pressure accuracy—all in under four seconds. Below you will find a dense but readable walk-through of definition, working principle, core parts, applications, specifications, trends, and maintenance keywords such as “COF bonding machine”, “Chip on Film bonder”, “LCD COF repair equipment”, “pulse heat COF machine”, and “4K TV bonding tool”.

What Exactly Is a COF Bonding Machine?

A COF bonding machine is a machine that attaches COFs to LCD OLED MINILED MICROLED FPC FFC PCB Ceramic and silicone substrates with ACF tapes. The bond must conduct vertically between bump and copper track yet stay insulated horizontally between neighboring 20 µm traces. When the film later folds behind the panel, the IC sits in the narrow bezel instead of on the glass, enabling edge-to-edge pictures in smartphones, OLED TVs, and 8K monitors. The same machine also reworks defective TV panels by removing the old IC and rebonding a new one, saving hundreds of dollars per screen.

How the Process Works Step by Step

Surface Prep: The bonding area is cleaned with ionized air and IPA to remove dust and oxide.
ACF Tacking: A short strip of ACF is cut by the built-in cutter and laminated to the film at 80 °C and 0.2 MPa.
Pre-Alignment: Up-looking and down-looking CCD cameras capture fiducial marks on the IC and on the film. Servo tables move in X, Y, θ to reach ±1 µm accuracy.
Pulse Heating: A titanium alloy head ramps from 25 °C to 180–220 °C in two seconds, stays within ±1 °C, then cools with auxiliary water or Peltier blocks.
Pressure Profiling: A closed-loop load cell applies 0.1–0.7 MPa while the adhesive flows. Parallel-bar mechanisms cancel the head’s own weight, so true force on the IC is known.
Cooling & Curing: Temperature drops below 60 °C under maintained pressure to freeze conductive particles in place.
In-Situ Testing: Four-wire Kelvin probes measure contact resistance across each bump; values above 50 mΩ trigger automatic rework.
Unloading: A soft-tip picker lifts the bonded film onto the output tray; the cycle restarts.

LCD repair machine

LCD Repair Machine

An LCD repair machine is a precision system that fixes cracked glass, failed TAB bonds, open ITO lines, color lines, and backlight problems in televisions, laptops, tablets, smartphones, and industrial monitors. Instead of throwing expensive panels away, service centers use these machines to restore original performance at component level. The following long-form article explains every angle of the technology so Google can easily index the keywords “LCD repair machine”, “TV panel repair equipment”, “laser LCD repair”, “TAB bonding machine”, “COF bonding machine”, “LCD freezing separator”, and related phrases.

1. What an LCD Repair Machine Really Is

An LCD repair machine is a collective name for several modules that separate, clean, bond, test, and sometimes laser-trim LCD glass. Each module targets a specific fault: outer glass cracks, polarizer scratches, flex cable delamination, driver IC failure, or internal short/open circuits inside the glass. Professional workshops combine these modules into one production line to handle 5″, 10″, 32″, 55″, 65″, 75″, even 100″ panels with the same daily throughput. The process is lead-free, ROHS friendly, and generates far less e-waste than replacing the whole display.

2. Main Types of LCD Repair Machines

2.1 LCD Freezing Separator Machine

The freezing separator repairs outer glass damage on phones and tablets. It cools the assembly to minus 140 °C with liquid nitrogen or compressed refrigerant. The low temperature embrittles the OCA glue so a steel wire slides between cover glass and the sensitive OLED or LCD underneath without force. After separation, the machine warms to room temperature, allowing easy pick-up of broken glass and leftover glue removal. The same cabinet can process 30–50 screens per hour with almost zero breakage when operators follow the correct recipe

2.2 Vacuum Hot-Plate Separator

A lower-cost alternative for shops that do not want liquid nitrogen. The hot plate heats the screen to 80–90 °C, while a vacuum chuck keeps the glass flat. A thin cutting wire then separates the glass. The method is slower but adequate for entry-level phone repair businesses.

2.3 TAB/COF ACF Bonding Machine

TAB (tape-automated bonding) and COF (chip-on-film) bonding machines repair flex cable failures in TV panels. A pulse-heated titanium head presses the flex against the LCD pad through anisotropic conductive film (ACF). The head ramps to 180–220 °C in two seconds, holds ±0.3 °C accuracy, then cools quickly to solidify the adhesive while conductive particles create vertical conductivity only. Modern models bond 4K/8K panels up to 100 inches with 1.5 µm alignment accuracy

2.4 Laser LCD Repair Machine

Laser systems fix internal glass defects such as bright lines, dark lines, half-lines, dot defects, short circuits, or ITO opens. A Nd:YAG or fiber laser fires microsecond pulses through a microscope objective to cut or link redundant bus lines inside the panel. Dual-wavelength machines (1064 nm + 532 nm) handle both metal and transparent oxide layers. Spot size can be as small as 3 µm, so the repair is invisible to the naked eye

2.5 Polarizer Laminator and Bubble Remover

After glass replacement or laser trimming, a new polarizing film must be laminated without dust or bubbles. The laminator uses a rubber roller in a Class-100 clean chamber to apply even pressure. A subsequent autoclave heats the stack to 45 °C under 0.4 MPa for 20 minutes to eliminate micro-bubbles.

3. Working Principle Step-by-Step

Fault Diagnosis: The operator powers the panel and checks for lines, spots, or no-image symptoms. A microscope or CCD camera captures the location.
Preparation: The defective area is cleaned with IPA. If the outer glass is cracked, the panel goes to the freezing separator first.
Separation: The machine cools or heats the glue line and separates the broken glass with cutting wire.
Glue Cleaning: A spin cleaner removes OCA residue with 530 rpm and alcohol mist.
Laser Repair (if needed): The glass is placed under the laser microscope. The software maps spare and main lines. Pulses either cut shorts or connect spare lines to bypass opens.
ACF Application: New TAB or COF flexes are tacked with fresh anisotropic film.
Bonding: The bonding head descends with programmed temperature, pressure, and time. Typical recipe: 200 °C, 1.5 MPa, 12 s.
Polarizer Lamination: A dust-free film is rolled onto the glass.
Autoclave: The panel is cured to remove bubbles.
Final Test: Power-on test confirms no lines, uniform backlight, and correct touch response.

The machine applies precise heat, pressure, and time parameters to ensure a secure and conductive connection. The primary function of the ACF bonding machine is to enable electrical conductivity in the vertical (Z-axis) direction while maintaining insulation in the horizontal (X and Y-axis) directions, thus preventing short circuits between adjacent circuits.

Working Principle

The working principle of an ACF bonding machine involves several key steps:

Application of ACF: The anisotropic conductive film is first applied to the substrate. This film contains conductive particles, which can be metallic or metal-coated plastic spheres, uniformly distributed within an adhesive matrix.
Alignment: The components to be bonded are carefully aligned using high-precision vision systems. Proper alignment is crucial to ensure that the conductive particles form the necessary electrical connections.
Bonding Process: The machine applies heat and pressure to the aligned components. The heat causes the adhesive in the ACF to soften and flow, while the pressure compresses the conductive particles between the contact pads of the components. This compression allows the particles to deform and create electrical pathways in the Z-axis direction.
