IC Bonder IC Bonding Machine

An IC bonder—also marketed as an IC bonding machine—is the micron-level bridge between naked silicon and the outside world. It picks a driver IC from a diced wafer, places it on glass (COG), plastic (COP), or a continuous reel (COF), and welds gold or copper bumps into anisotropic conductive film (ACF) in under two seconds. Every smartphone OLED, foldable tablet, 8-K TV, and automotive cluster you touch has passed through such a bonder. This guide explains physics, hardware, software, specs, applications, trends, and maintenance so Google instantly ranks you for “IC bonder”, “IC bonding machine”, “COG IC bonder”, “COP IC bonding machine”, “COF IC bonder”, “display driver IC bonding”, and every high-value permutation.

1. What Exactly Is an IC Bonder / IC Bonding Machine?

An IC bonding machine is a servo-driven, vision-guided, pulse-heat press that bonds a bare integrated-circuit die to a substrate—glass, plastic, or flexible tape—using anisotropic conductive film (ACF). The goal is electrical contact in the Z-axis only, eliminating short circuits laterally. The same platform reworks defective assemblies by removing the old ACF and rebonding a new die, saving a $300 TV panel or a $150 phone OLED. Modern bonders achieve ±1 µm alignment, ±0.5 °C temperature stability, and 0.1 g force resolution on die sizes from 0.25 × 0.25 mm to 25 × 25 mm.

2. Physics Common to COG, COP, and COF

Bump Formation: Gold or copper bumps 5–25 µm high are plated on the IC during wafer-level bumping (BP).
ACF Lamination: 25–45 µm anisotropic conductive film is tacked to the substrate at 80 °C, 0.2 MPa.
Vision Alignment: Dual 12 MP cameras capture fiducials on die and substrate; AI edge detection calculates offset in X, Y, θ, and scale within ±1 µm @ 3σ.
Pulse Heat & Pressure:
- COG: 180–220 °C, 1.0–1.5 MPa, 1.5 s
- COP: 140–180 °C, 0.6–1.0 MPa, 1.5 s (PET-friendly)
- COF: 180–220 °C, 1.0–1.5 MPa, 2.0 s (index time included)
Cool Under Load to < 60 °C while maintaining pressure, locking conductive particles.
In-Situ Kelvin Test < 30 mΩ per bump; > 30 mΩ triggers automatic rework.
