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

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

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.

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.

COG bonding machine

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

6. Pre-Bond: Head descends to 50 °C and 0.1 MPa to tack the IC; machine verifies bump-to-pad overlap ≥ 90 %.
7. 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.
8. Cool Under Load: Water-cooled block drops temperature below 60 °C in 1 s while pressure holds, preventing voids.

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

1. Fault Diagnosis: The operator powers the panel and checks for lines, spots, or no-image symptoms. A microscope or CCD camera captures the location.
2. Preparation: The defective area is cleaned with IPA. If the outer glass is cracked, the panel goes to the freezing separator first.
3. Separation: The machine cools or heats the glue line and separates the broken glass with cutting wire.
4. Glue Cleaning: A spin cleaner removes OCA residue with 530 rpm and alcohol mist.
5. 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.
6. ACF Application: New TAB or COF flexes are tacked with fresh anisotropic film.
7. Bonding: The bonding head descends with programmed temperature, pressure, and time. Typical recipe: 200 °C, 1.5 MPa, 12 s.
8. Polarizer Lamination: A dust-free film is rolled onto the glass.
9. Autoclave: The panel is cured to remove bubbles.
10. Final Test: Power-on test confirms no lines, uniform backlight, and correct touch response.
