Traditional COB vs Flip Chip COB LED Technology: A Complete Guide
In the world of LED display and lighting solutions, COB (Chip on Board) technology has played a crucial role in shaping modern applications. Over the years, two major approaches have emerged— Traditional COB and Flip Chip COB . While both serve similar purposes, they differ significantly in design, performance, cost, and reliability. Let’s explore each in detail. Traditional COB Technology Traditional COB is a widely used method where LED chips are directly mounted on a PCB (Printed Circuit Board) with the help of wire bonding. These tiny gold or aluminum wires connect the LED chip to the circuit, while protective encapsulation safeguards the chip and ensures even light distribution. Key Features of Traditional COB: Cost-Effective: Uses mature manufacturing methods, making it suitable for cost-sensitive projects. High Light Output: Enables high-density chip placement for brighter designs. Thermal Limitations: Heat dissipation relies heavily on the PCB and externa...
