I delivered the first phase of a project to a new client. A passive test fixture for HEMT transistors that must operate at 1000Vdc and 200C continuous operation for 1000's of hours. Not super high tech but I did need to learn some new things to make this work.
The next phase is more complex with a custom embedded oven, temperature controller using a Microchip and data logging to boot with a custom Visual C++ GUI. The data logging will record temperature and Drain leakage current as the device is stressed over time.
I'll update the blog as interesting problems arise on this project.
