: Types of IC Packages
2023/3/26
There are way too many different types of semiconductor (IC or transistor) packages. For example, SOP, QFN and BGA are some of the package names, but it is very difficult to understand which package represents which shape. Therefore, in this article, we have summarized the types and characteristics of each package in an easy-to-understand manner using diagrams. We hope you will find it helpful. List of IC Package Types The figure above shows the classification of packages. Packages can be broadly classified according to the following aspects. Difference in mounting method Whether the mounting method is "insertion mounting" or "surface ...
