OL-COF156 – 15.6-Inch Single-Side Multi-Zone Pre-Bonding Machine

OL-COF156 – 15.6-Inch Single-Side Multi-Zone Pre-Bonding Machine

Precision Thermal Alignment System for COF/IC to LCD Panel Assembly

The OL-COF156 by Olian Automatic Equipment Co., Ltd. is a semi-automatic pre-bonding machine engineered for the initial alignment and temporary bonding of Chip-on-Film (COF) or bare IC chips onto large-format rigid LCD panels up to 15.6 inches. Designed as the critical first step in the FOG (Film-on-Glass) or COG (Chip-on-Glass) process chain, this system ensures accurate terminal registration and secure tacking before final main bonding—dramatically reducing misalignment defects and rework rates.

Unlike full bonding machines, the OL-COF156 focuses exclusively on pre-compression: applying controlled heat and pressure to activate the ACF just enough to hold components in place during transfer to the main bonder.

🔍 Key Applications

• Pre-bonding of COF tapes and driver ICs onto LCD/OLED display panels
• Temporary fixation of touch sensor flex circuits
• High-mix production of industrial, automotive, medical, and consumer displays
• Ideal for panels requiring multi-segment or single-edge bonding

⚠️ Note: This machine performs pre-bonding only—it does not apply ACF, conduct final bonding, or support double-side processing.

🔄 Typical Workflow

1. Load Panel: Operator places clean LCD panel onto the platform.
2. Fixturing: Activates vacuum to hold panel flat.
3. Place COF/IC: Manually positions COF tape or IC chip onto ACF-pre-laminated area.
4. Visual Alignment: Uses external microscope or camera (user-provided) for fine adjustment.
5. Pre-Bond: Selects auto/manual mode, sets parameters, and initiates cycle.
6. Unload: Removes pre-bonded panel for transfer to main bonder.

Cycle time is typically under 20 seconds, depending on operator skill and product complexity.
