PLCC 2 LED, or Plastic Leadless Chip Carrier 2, is a type of surface mount technology (SMT) component that has gained significant popularity in the electronics industry. This article aims to provide an in-depth introduction to PLCC 2 LED, covering its design, applications, advantages, and market trends.

Introduction to PLCC 2 LED

The PLCC 2 LED is a compact and efficient light-emitting diode (LED) package that is widely used in various electronic devices. It is characterized by its small size, which allows for high-density mounting on printed circuit boards (PCBs). The PLCC 2 package consists of a plastic substrate, a die, and a lead frame. The die is the light-emitting element, while the lead frame provides electrical connections to the PCB.

Design and Structure

The PLCC 2 LED package is designed with a flat top, which makes it easy to mount on PCBs. The lead frame is typically made of copper or other conductive materials, and it is attached to the plastic substrate using a reflow soldering process. The die is then mounted on the substrate and connected to the lead frame through metal bonding or wire bonding techniques. The PLCC 2 package is available in various sizes, ranging from 2.0mm x 2.0mm to 3.0mm x 3.0mm. The size of the package determines the amount of light it can emit and the viewing angle. Larger packages generally provide higher brightness and wider viewing angles.
