SOT Components – CAD Library Series: Part 2

In part 2 of this 4 part  CAD library white paper series we cover  Small Outline Transistor (SOT)  components.

As mentioned in Part 1 of this series that focused on Molded Body components, there are dozens of different things to consider when creating a CAD library including the precision of the part placement, via fanout, trace routing, post processing, fabrication and assembly processes.

SOT 1thru4



This CAD library whitepaper is the second in this series and is dedicated to each aspect that should be considered when creating Small Outline Transistor (SOT) library parts. It also describes the impact each feature has in the PCB process.

The SOT component family includes several package types: the flat lead SOTFL, the SOT23’s in 3, 5, 6 and 8 gull wing lead packages, the SOT143 and 343 packages and the SOT 223. This paper discusses everything from the package types to the silkscreen, and from the placement courtyard to via fanout examples.
