How to identify chip packages

A chip package is what surrounds the integrated circuit die and connects the die's pads to the packages external pins. They are often a chip carriers, or IC packages.

Types of Leads/Contacts

The pieces of metal that electrically connect the IC to a circuit board are called leads.
