COB Die Bonding Services
What is the COB Process?
COB (Chip-On-Board) refers to a technique where semiconductor chips are directly mounted and bonded onto a printed circuit board (PCB) without traditional packaging. In this method, the chip is exposed and electrically connected directly to the board.
Advantages:
- High Placement Precision: COB die bonding offers superior accuracy, which is especially beneficial for mid- to long-term chip development needs.
- Lower Material Costs: Compared to traditional SMD packaging, COB reduces the need for additional packaging materials, leading to cost savings.
- Advanced Mass Transfer Capability: GIO has developed and implemented its own proprietary COB die bonding process with mass transfer capabilities. This process enhances flatness and placement uniformity, making it particularly well-suited for high-resolution flexible and rigid displays.
- Time Efficiency: Our optimized bonding process significantly shortens the overall die bonding cycle, improving production throughput.
