What Is an IC Package?
An IC package is a case component attached to semiconductor chips. It serves multiple functions, including supplying power, protecting the chip from external environmental factors, transmitting signals to and from the chip, and enhancing chip performance.
Applications of IC Packages
These packages are integral to a wide range of devices, from smartphones and tablets to various sophisticated electronic devices in homes. As technology evolves, there is a growing demand for smaller, lighter, and more functional packages. They are also adapting to incorporate multiple mechanisms in a single package, especially in sensor devices that operate on multiple wavelengths.
Principle of IC Package
IC packages consist of structures for electrical connection and protection. Electrical connections often use gold plating for high-specification applications. The protective part, known as the sealing material, has traditionally used metal but is now increasingly using resin-based materials for weight and cost efficiency. Ceramics are also gaining popularity due to their superior properties.
Types of IC Packages
Package types vary based on the terminal extension method and the material used for the package body. They range from plastic packages to ceramic packages and include:
1. System In Package (SIP)
Encapsulates multiple chips in one package, suitable for cost reduction and insertion mounting, with excellent heat dissipation performance.
2. Small Outline Package (SOP)
Features terminals extending in two directions, often used for small semiconductor chips.
3. Quad Flat Package (QFP)
Has terminals extending in four directions, suitable for various applications.
4. Land Grid Array (LGA)
Includes terminals at the package bottom, allowing for grid-pattern socket mounting.
