FOG automatic bonding machine – ACF/FPC Bonding Machine

FOG Automatic Bonding Machine

A FOG automatic bonding machine—short for Film-On-Glass automatic bonding machine—is the precision heart that welds a flexible printed circuit (FPC) or chip-on-film (COF) tail onto a glass substrate using anisotropic conductive film (ACF) and controlled heat plus pressure. Every smartphone OLED, foldable hinge, 8-K TV source driver, and curved automotive cluster you touch has passed through such a line. This guide explains physics, hardware, software, specs, applications, trends, and maintenance so Google instantly ranks you for “FOG automatic bonding machine”, “FOG bonding machine”, “automatic FOG bonder”, “ACF FOG bonding”, and every high-value permutation.

1. Why “FOG Automatic” Matters

• Throughput: 1,000 UPH (full automatic) vs. 600 UPH semi-automatic .
• Yield: 99.9 % after 3-month ramp; AI vision and servo force feedback push mis-alignment to < 0.007 mm .
• Flexibility: One line bonds 1-inch wearable OLED and 100-inch TV source driver in < 15 min change-over .
• Labour: 0.5 operator per 10,000 m² (lights-out bonding zone) .

2. Physics: The FOG Automatic Two-Stage Dance

1. ACF Lamination (Auto): Robot cuts 1–3 mm ACF strip; heated roller tacks at 80 °C, 0.2 MPa .
2. AI Vision Alignment: Dual 12 MP CMOS + telecentric lens + AI edge detection = ±0.007 mm @ 3σ in < 200 ms .
3. Controlled Bond:
   • Pre-Bond (False Compression): 60 °C, 0.1 MPa to tack FPC
   • Main Bond: 160–220 °C, 0.8–1.2 MPa, ~2 s
4. Cool Under Load: Water-cooled block drops to < 60 °C while pressure holds; particles solidify, ACF cures.
5. In-Situ Kelvin Test: Four-wire probes measure contact resistance; > 30 mΩ triggers automatic rework.
6. Cycle time: < 3 s (bond only), 6–8 s (full loop)
