Completing a Circuit

At this point it is clear to you that electricity cannot move without a complete path. When designing a circuit board, a common return path is created that is called ground.

Ground shows up prominently in all aspects of the PC and in this book.

Connection Point Ground

A connection point that is ground for a PC component is typically known as pin 1.


[spacer] Identifying Pin 1

Sometimes Identifying Pin 1 can be an elusive task. Frequently a trick that works is to look at the backside of a circuit board and looked for a solder connection that is square instead of round. If you can find that, you found pin one.


Figure 9: Notice the one connection point is square. This indicates Pin 1 or ground.
