Circuit Designers And Builders: You Need To Understand IC Packages

Integrated circuits (ICs) are etched into tiny silicon chips. ICs may be part of larger electronic circuits or they may be a complete system by themselves. These components are packaged in ceramic, plastic, leadless or glass.


The sizes of the packages have assigned names and specifications. Often, we finish design with a particular IC without considering the type of packages available for such IC and the problem of soldering or placing the component shows up.


This is a common problem among hobbyists and students. In order to avoid this in your next project, try and check for the package type before you move on.
