1. The LED PCB Structure
2. The PCB Material
LED PCBs are typically made from FR4, a common fiberglass-reinforced laminate material that is widely used in electronics manufacturing. FR4 is highly resistant to heat, moisture, and chemical corrosion, making it the ideal choice for LED PCBs.
3. The LED Placement
LEDs are placed on the copper layer of the PCB through a process called SMT (Surface Mount Technology) or through-hole technology. SMT is the process of mounting surface-mounted components onto the surface of the PCB, while through-hole technology involves soldering components through drilled holes in the board. In either case, the goal is to ensure that the LEDs are positioned correctly for optimal performance and light output.
