Greetings; I am designing a voltage reference board and the reference voltage ic is a lm399. The lm399 uses a built in heater to keep the temp of the part constant.
The heat from this part can affect the surrounding components which in turn affect the overall accuracy of the design. What I would like to do is confine the heat generated by the lm399, to just that part and not allow it to just spread across the board. My question then is can anyone recommend methods to do what I need, that is thermally isolate the lm399. One method from a app note was to cut slots around the part. Are there any other suggestions?
Thanks.
