ATS recently was interviewed by SMT Magazine about what research instruments are used to do the necessary thermal analysis to develop a thermal management solution, including an aluminum heatsink, copper heatsink or other kind of heatsink.
The demo shows a wind tunnel, sensors, differential pressure system, and thermal measurement system and their use.  We do an actual demo of how to use the equipment all in five minutes.  Have a look at this link here, “PCBA in Wind Tunnel Demo at SMT” or at SMT Magazine’s site directly
