发明名称 Ovenized oscillator
摘要 An ovenized oscillator package including a ball grid array substrate seated on a circuit board, a heater and a temperature sensor mounted on the ball grid array substrate, and a crystal package mounted to the ball grid array substrate and overlying at least the heater. A layer of thermally conductive epoxy or adhesive material couples the heater to the crystal package. Stabilizer posts, which are made of an insulative adhesive or epoxy material, are formed between the ball grid array substrate and the circuit board for stabilizing and relieving the stress on the ball grid array substrate. A lid is seated on the circuit board and covers and defines an oven for the ball grid array substrate.
