Layer and Packaging In our design, we need to use Eagle to make

Library, Schematic, and board. These are then sent to the fabrication company for printing.

There are two things that we need to address:1. The cost: in order to be cost efficiency, we

used a 4 layer design.2. To the concern of solderability and

availability; we chose a specific packaging format. TSSOP (and so on)

Availability of componentsWe ordered most of our components via

DigiKey and TSSOP. They carry the more popular types at low cost with plenty of stock.

One Library Eagle doesn’t have all the IC and components

that we use, so we need to create the library. There are three steps to make a library: 1. symbol 2. package 3. connect them

One LibraryHere is the procedure to make an IC library:
