Description

technical field [0001] The invention relates to the technical field of quartz crystal oscillators, in particular to a composite quartz crystal oscillator. Background technique [0002] Crystal oscillators, derived from polyhedral quartz rods, are first cut into gleaming hexahedral rods, and then after repeated cutting and grinding, the quartz rods are finally made into a stack of thin discs, each disc is trimmed and polished and cleaning, and finally plated with metal electrodes, fully plated on the front, and plated with a keyhole shape on the back. After testing, the package can be used in the factory. [0003] The existing composite quartz crystal oscillator is not perfect in terms of heat dissipation. Under long-term use, the quartz crystal oscillator will often damage the composite quartz crystal oscillator due to the accumulation of heat, thereby reducing the service life of the crystal oscillator and speeding up the life of the crystal oscillator. Replacement increas...

[0005] Aiming at the deficiencies of the prior art, the present invention provides a composite quartz crystal oscillator, which has the advantages of good heat dissipation effect, etc., and solves the problem that the existing composite quartz crystal oscillator is not perfect in heat dissipation, and the quartz crystal oscillator is under long-term use. Often due to the accumulation of heat, the composite quartz crystal oscillator will be damaged, thereby reducing the service life of the crystal oscillator, speeding up the replacement of the crystal oscillator, and increasing the economic cost. For processing, the electrodes are often metals dissolved in acidic solutions, which increases the cost of recycling
