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”.
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.

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.

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.
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.
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
.
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.
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
.
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
.
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.

AI-driven vision will auto-select laser cut or link paths, reducing technician training time. IoT modules will send yield data to cloud dashboards for predictive maintenance. Green refrigerants will replace liquid nitrogen in freezing separators, cutting operating cost by 30%. Roll-to-roll ACF will enable continuous bonding of ultra-wide 110″ panels. Micro-LED hybrid displays will adopt the same laser micro-machining platforms, extending the machine’s useful life well into the next decade.
An LCD repair machine is no longer a single-purpose tool; it is a strategic investment that restores value to damaged displays, supports environmental goals, and delivers rapid return on investment across smartphones, TVs, laptops, automotive, and industrial applications. By choosing the right combination of freezing separation, TAB/COF bonding, laser trimming, and polarizer lamination modules, service centers can handle virtually any LCD faults.

These components play a crucial role in the production line, from initial material preparation to final product testing. Here is a comprehensive overview of the parts and accessories used in ACF bonding processes:
ACF Tape is the core material used in the ACF bonding process. It is an epoxy adhesive system filled with conductive particles that provide electrical interconnection between pads through the film thickness (z-direction). The conductive particles are distributed far apart to ensure electrical insulation in the plane direction (X&Y) of the film. ACF tape is available in various models and is specific to the application for which it is designed. For example, ACF designed for flex-on-glass (FOG) assembly is usually not suitable for chip-on-glass (COG) or chip-on-film (COF) applications.
The Hot Bar or Thermode is the primary tool used to apply heat and pressure during the ACF bonding process. Hot bar bonding systems are designed to heat the hot bar to a specific temperature using low voltage electricity, which temperature is fed back to the controller via a thermocouple. The hot bar is brought into contact with the ACF film over the bonding pad, heated to the bonding temperature, and held for a specified time. This process produces the connection between the ACF tape and the components.
Bonding Heads are designed to hold the components and position the ACF tape correctly with the conductive pads on the PCB or other components. They ensure that the bonding process is accurate and consistent. Bonding heads can be manual or automated, depending on the specific requirements of the bonding process.
ACF Cutting Machines are used to cut the ACF tape to the required length and shape. These machines ensure that the ACF tape is accurately cut and positioned for the bonding process. The cutting is done using the half-cut method, where only the actual ACF material is cut, and the cover-layer is used for tape transport.
Pre-Bonding Machines are used to pre-bond ICs or COF on the panel that has been attached to the ACF. The pick and place of the panel is achieved manually, and the pre-alignment is automatically completed by the equipment.
