JQI Short Course: Building custom electronic instrumentation

Hints for successful printed circuit board layout and use of modern commercial components
May 29, 2013 - 1:00pm
Alessandro Restelli
Joint Quantum Institute

Two Course lecture series, May 29th and May 30th (please note, this course will be in two parts, the first on May 29th from 1pm - 3pm and finishing on May 30th from 1pm - 3pm)

In modern Physics laboratories building custom electronic instrumentation is a fundamental step in the design of many cutting-edge experiments. Often commercial instrumentation is not available for a particular experiment simply because, due to the novelty of the setup, the needed functionality or specification has never been required before. Design and troubleshooting of analogue or mixed analogue-digital electronics is therefore an important and increasingly required set of skills in the career of an experimental physicist. In this seminar I will provide suggestions and rules of thumb for successful PCB (printed circuit board) layout using modern SMDs (surface mount devices). Some of the topics covered during the seminar will be: reduction of interference and ground loops in low noise and high frequency analog design, differential signaling, power supply design and successfully mechanical assembly and troubleshooting during prototyping.
