Introduction to LED Diodes for PCB Boards

LED diodes for PCB boards are specialized electronic components that emit light when an electric current passes through them. They are commonly used in a wide range of applications, including consumer electronics, automotive, medical devices, and industrial equipment. These diodes are designed to be directly mounted onto PCBs, which allows for greater design flexibility and space efficiency.

Types of LED Diodes for PCB Boards

There are several types of LED diodes available for PCB boards, each with its own unique characteristics and applications. Some of the most common types include: - Through-Hole LEDs: These LEDs have leads that extend through the PCB, allowing for easy mounting and soldering. They are suitable for applications where heat dissipation is not a concern. - SMD (Surface Mount Devices) LEDs: SMD LEDs are mounted directly onto the surface of the PCB, offering a smaller footprint and greater design flexibility. They are ideal for applications where space is limited. - COB (Chip-On-Board) LEDs: COB LEDs have the LED chip directly mounted onto the PCB, eliminating the need for leads. This results in a compact and efficient design, making them suitable for high-intensity lighting applications. - Module LEDs: Module LEDs are pre-assembled LED units that can be mounted directly onto the PCB. They are often used in applications that require a high level of brightness and uniformity.
