Abstract:
A temperature stabilization scheme for a circuit board, comprising:an isolated region within the circuit board, coupled to a remainder ofthe circuit board via at least one electrical pathway, each of the at least one electrical pathway having an incidental thermal conduction path between the isolated region and the remainder of the circuit board; an electronic system implemented on the circuit board; a temperature sensitive component within the electronic system and coupled to a mounting site on the isolated region; and a series of heaters thermally coupled to the isolated region, providing a compensating thermal profile that opposes, over a portion of the isolated region that includes at least the mounting site, a thermal instability caused by the incidental thermal conduction path of the at least one electrical pathway, and that has at least one of an offset component setting the portion of the isolated region to a predetermined average temperature and a slope component making the portion of the isolated region isothermal.
