PADS POWERPCB TUTORIAL


The Design Object

The purpose of this particular tutorial is to create a 4 Layer PCB for the following Circuit.



* The Schematics has been drawn in Orcad. If you are not familiar with Orcad, you may like to take an Orcad tutorial.

* Although this "simple circuit" can be done using a two layer board, we are making it 4 Layer board to understand the concepts of Power and Ground Layers.

* As shown in the Schematics, the circuit uses three components

R1
J1
D1

* As far as the functionality is concerned, the circuit is used to make an led D1 glow when a Power Supply is connected at the connector J1.

* Each component will have an associated footprint. We have given the followintg names to the footprints of the components used.

Component Footprint Name
R1 R0603_1
J1 HEADER2
D1 LED


In the next few pages we will be creating footprints of the three components.
