History of Chip LED SMD

The journey of chip LED SMD began in the late 20th century when researchers and engineers started exploring the potential of light-emitting diodes (LEDs). Initially, LEDs were bulky and inefficient, but with advancements in semiconductor technology, they evolved into smaller, more efficient devices. The first chip LED was developed in the 1970s, and it was a significant breakthrough in the lighting industry. In the 1980s, the introduction of the surface mount technology (SMT) further enhanced the efficiency and compactness of LEDs. SMT allowed for the direct attachment of components onto the printed circuit board (PCB), reducing the size of the LED devices. This technology paved the way for the development of chip LED SMD, which became widely adopted in various applications.
