January General Meeting

Designing and Building Printed Circuit Boards on a Shoestring Budget

Speaker: Chuck Rohs, Endpoint Security Developer, Cisco Systems, Inc.

Chuck Rohs presenting

Many people like to tinker with development boards — e.g., Arduino, Raspberry Pi, BeagleBoard, ODROID, ESP8266, etc. — or build electronic projects from discrete components. Frequently these projects end up being a rat's nest of wires on a breadboard. What many people don't realize is that designing and building a printed circuit board (PCB) is easily within the reach of the hobbyist, with a few simple tools. Developing a PCB can sometimes be easier than prototyping, allows for a more robust mechanically stable project, and the possibility of easily making multiple boards for family or friends.

This discussion will illustrate the steps involved in printed circuit board design and manufacturing at the hobbyist level by reverse engineering a Raspberry Pi Amplifier "HAT". This discussion will cover:

  • Board inspection for reverse engineering
  • Component determination
  • Examination of reference designs of key parts
  • Schematic capture (in Protel)
  • Bill of materials
  • Footprint generation
  • Board fabrication (DirtyPCBs)
  • Board paste-up and reflow
  • Tools required

Chuck Rohs is an endpoint security developer at Cisco Systems, Inc. Chuck has a background in embedded software development and security, and was a founder of Au-Zone Technologies Inc.
