Foreword: What Is an LED PCB?
An LED PCB is a printed circuit board specially made for LED circuits since they produce a great amount of heat energy. LED PCBs are metal-based MCPCBS, and their substrate is aluminum, which has good thermal conductivity.
LED PCBs are made of a special thin layer of thermally conductive material which dissipates heat quickly as compared to the usual PCB boards. Aluminum is the main material used in LED circuit boards.
