发明名称 Thermally isolated ovenized crystal oscillator
摘要 Heat-generating ovenized crystal oscillators can be directly mounted to a circuit board. Thermal isolation of an OCO from heat-sinking circuit board material and other temperature-sensitive components on a circuit board is accomplished by means of perforations (12) in the circuit board that surround the mounting area of the OCO on the board.
