An LCD-TFT-OLED-ACF-COF-IC-FPC bonding machine is the precision heart that welds chips, flex circuits, and 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 “LCD bonding machine”, “TFT bonding machine”, “OLED bonding machine”, “ACF bonding machine”, “COF bonding machine”, “IC bonding machine”, “FPC bonding machine”, and every high-value permutation.
OLED – Organic Light-Emitting Diode (the flexible/emissive panel)
ACF – Anisotropic Conductive Film (the common adhesive)
COG – Chip-On-Glass
COF – Chip-On-Film (reel-fed copper tail)
IC – Integrated Circuit (the driver die)
FPC – Flexible Printed Circuit (the soft tail)
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
ACF Lamination (Tack): Low temperature (80 °C) and low pressure (0.2 MPa) activate the adhesive just enough to hold the film in place.
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.
3. Step-by-Step Fully Automatic Workflow
Robot Loading: 6-axis arm feeds LCD/TFT/OLED glass, flex, or plastic reel; barcode scanner confirms product ID.
Atmospheric Plasma Cleaning: Raises surface energy to > 60 dynes for ACF wetting.
ACF Lamination: Precision cutter feeds 1–3 mm strip; heated roller tacks film at 80 °C, 0.2 MPa.
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 .
Controlled Bond:
LCD/TFT/OLED COG: 180–220 °C, 0.8–1.5 MPa, ~2 s
