[edit] Introduction

The Cubesat structure and it's P-POD deployer were developed by California Polytechnic State University, San Luis Obispo, also known as CalPoly.

[edit] CAPE1

The following is work done by the first satellite team.

[edit] Express PCB

Express PCB and its supporting software was used to design PC boards for CAPE1. Several issues have come up dealing with this method.

• Angles on boards can be an issue. JW writes:

One tip to get in the habit of doing is to use 45 degree angle turns. Typically, circuit board designers will use 45 degree angle (135 inside angle) bends. Probably the main reason for doing this is to make orthogonal crossing of signals on different layers easier. The reasons for using 45 degree angles aren't really applicable in this case, but it's a good habit to get into. Also, angles greater than 90 degrees may become acid traps in the etching process.

• Spacing between traces can be an issue. In the early phases of PC design, JW noticed several traces in which they were connected. After evaluating the CAD design, it seems that the ExpressPCB software will allow the user to place traces closer together than what can be successfully done in the factory without creating a short.
