LED PCB (Light Emitting Diode Printed Circuit Board) is a type of printed circuit board specifically designed for LED lighting devices, widely used in LED lamps, displays, and backlight modules. This design is particularly useful for high-power LED applications and other electronics that generate significant heat. It provides electrical connections, mechanical support, and thermal conduction — three things every LED needs to work safely. This blog will explain the basics of LED PCB assembly, including how it works, how it's made, and common issues.
