LED PLCC 4, or Quad Flat Package with Leadless Chip Carrier 4, is a type of semiconductor packaging technology widely used in the LED industry. This article aims to provide an in-depth introduction to LED PLCC 4, covering its basic structure, advantages, applications, and market trends.

Basic Structure of LED PLCC 4

LED PLCC 4 is a leadless chip carrier packaging technology that has four leads on each side. The basic structure of LED PLCC 4 includes the following components: substrate, die, lead frame, encapsulant, and protective layer. The substrate is typically made of ceramic or glass, which provides a stable foundation for the die. The die is the core component of the LED, which emits light when an electric current passes through it. The lead frame is a metal frame that supports the die and connects it to the external circuit. The encapsulant is a protective material that covers the die and lead frame, ensuring electrical insulation and protecting the LED from external damage. The protective layer is used to further protect the encapsulant and enhance the overall durability of the LED PLCC 4 package.
