Chip on board (COB) is the latest innovation in the field of LED technology. It is a method of directly mounting red, green and blue chips onto a printed circuit board (PCB). As COB technology involves bonding the components to PCB using an adhesive, so it is more robust and reliable connection. This makes it less susceptible to failure due to external factors and soldering issues.
Let’s explore the other benefits of COB over SMD/ DIP products
Application Scenarios
Monitoring center, Conference room, Audio- Visual center, Product Show room, Exhibition hall, Brand Chain store, Commercial center, Broadcasting center, Cinema.
