PLCC 2, or Plastic Leaded Chip Carrier 2, is a type of electronic packaging technology that has been widely used in the semiconductor industry. This article aims to provide an in-depth introduction to PLCC 2, covering its history, characteristics, applications, and future prospects.
History of PLCC 2
PLCC 2 was first introduced in the late 1980s by Japanese electronics manufacturer Hitachi. It was designed to be a smaller, more compact alternative to the traditional ceramic DIP (Dual In-line Package) packages. Since then, PLCC 2 has become one of the most popular packaging technologies for surface-mount devices (SMDs) in the electronics industry.
Characteristics of PLCC 2
PLCC 2 packages have several distinct characteristics that make them suitable for various applications:
- Small Size: PLCC 2 packages are significantly smaller than their ceramic DIP counterparts, allowing for higher component density on printed circuit boards (PCBs).
- Low Profile: The low-profile design of PLCC 2 packages helps to reduce the overall height of the PCB, making it ideal for space-constrained applications.
- Lead-free Soldering: PLCC 2 packages can be soldered using lead-free soldering processes, which are becoming increasingly popular due to environmental concerns.
- High Reliability: PLCC 2 packages are known for their high reliability, thanks to their robust construction and good thermal performance.
