IV Curve Tracing
The application is a semiconductor device test and the device is a transistor. The Vektrex current source that is most appropriate for curve tracing is the SpikeSafe SMU.
Jeff Hulett is the Founder and CTO of Vektrex Electronic Systems, Inc. Because of his vision and leadership, the company grew from a start-up to the market leader. Hulett is the Chief Architect for Vektrex products.
Junction Temperature is the basis for every semiconductor device design. Knowledge of junction temperature and thermal resistance is useful at all stages of semiconductor production from R&D to characterization and quality assurance.
LIV testing is a key step in determining the functionality of laser diodes, LEDs and LIDARs. Visit the LED Testing category page to get more information on related topics such as Staircase Sweep, IV Curves and the SpikeSafe Source Measure Unit.
MCPCB and other load boards for LED and semiconductor device test are equally, if not more important as the equipment. There are many variables associated with load boards to be taken into consideration when planning for a long term reliability, burn-in or LM-80 test.
Measurement repeatability is extremely important to achieve in order to save time and money while testing LEDs and laser diodes. SpikeSafe Current Sources and Source Measure Units make repeatable measurements easy to achieve.
