Wire bonding is a common technique used in the assembly of electronics, including COB (Chip-on-Board) LED module displays. In COB displays, multiple LED chips are directly mounted on a PCB (Printed Circuit Board) without using individual packages. Wire bonding is the process of connecting the LED chips to the PCB using extremely thin wires made of gold, aluminum, or copper. These wires are carefully bonded to the designated bonding pads on the LED chips and the PCB using specialized equipment.
COB LED module displays from Guangzhou Junchen Group Purchase Co., Ltd. are designed to provide a compact, high-density, energy-efficient, and durable solution for various applications such as digital signage, information display, and home theater.
