description

thermal management of electronic system, like any other problem, requires two independent solutions. one such solution is measurement. this tutorial is offered to familiarize the audience with the basic principles of measuring temperature, velocity, and pressure and heat flux in electronics systems. the tutorial will cover a host of topics in thermal measurement and uncertainty analysis along with the assessing the role of bad data in product design. the course is closed with a live and hands-on demo of how to use such sensors and measure t, v, p and heat flux sensors in wind tunnel testing of heat sink and pcb.

goal

to provide the participants with the best practice of thermal measurement in electronics application and provide a hands-on experience on these best practices.

who should attend

managers and engineer’s engaged in the design of electronic systems which require measurement for design verification and subsequent product release.

course syllabus
