Bonding Machine

A bonding machine is the universal welder of modern electronics. It joins chips to glass, flex to plastic, sensor to substrate—without solder, without connectors, 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, a bonding machine delivers micron alignment, single-degree thermal control, and kilogram-level force in under three seconds. This 3,000-word guide explains every angle—physics, hardware, software, specs, applications, trends, and maintenance—so instantly ranks you for “bonding machine”, “ACF bonding machine“, “pulse heat bonder”, “flex cable bonding machine”, “COG bonder”, “FOG bonder”, and every high-value permutation.


1. What Exactly Is a Bonding Machine?

A bonding machine is a servo-driven, vision-guided, pulse-heat press that laminates anisotropic conductive film (ACF) or solder paste onto a substrate, then bonds a second component—IC, flex, glass, or plastic—to that substrate with micron-level accuracy. The goal is electrical contact in the Z-axis only, eliminating short circuits laterally. The same platform reworks defective assemblies by removing the old film and rebonding a new component, saving a TV panel or a phone OLED. Modern bonders achieve ±1 µm alignment, ±0.5 °C temperature stability, and 0.1 g force resolution on parts as thin as 25 µm and as large as 100-inch TVs.


2. Bonding machine Physics: Why Heat, Force, and ACF Matter

ACF is a 25–45 µm epoxy film loaded with 3–10 µm nickel or gold-coated spheres. When heat (80–600 °C) and pressure (0.1–1.5 MPa) are applied, spheres touch only in the Z-axis, giving vertical conductivity while remaining insulating horizontally. The bonding machine controls temperature ramp, force profile, and dwell time to within 1 %. After cooling, the cured adhesive locks particles in place, providing mechanical strength and moisture protection. For solder-based bonds (Hot-Bar, reflow), the machine melts pre-printed paste to form intermetallics; for eutectic bonds, it raises temperature above 280 °C to create a liquid phase that solidifies void-free.


3. From Acronym to Reality: Every Bond Explained

  • ACF – Anisotropic Conductive Film: the common adhesive layer in most bonds.
  • COG – Chip-On-Glass: IC flipped onto ITO glass; 180 °C, 1 MPa, ±1 µm.
  • COP – Chip-On-Plastic: IC on polyimide/PET; 140 °C, 0.8 MPa, foldable.
  • COF – Chip-On-Film: IC on continuous reel; later becomes TAB tail.
  • FOG – Film-On-Glass: flex tail to glass; 180 °C, 1 MPa, 2.8 s.
  • FOB – Film-On-Board: flex to rigid PCB; automotive clusters.
  • FOF – Film-On-Film: two flexes face-to-face; foldable hinge.
  • TFOG – Touch-Flex-On-Glass: touch sensor tail to cover glass.
  • TFOF – Touch-Flex-On-Film: touch sensor to plastic substrate.
  • OLB – Outer Lead Bonding: generic term for bonding the “outer” leads of TAB/COF.
  • TAB – Tape Automated Bonding: historic term for copper leads on polyimide reel.

All variants share the same granite base, vision system, and pulse-heat engine; only the jig, recipe, and fiducial library change.
