Method of adjusting the frequency of a crystal resonator and reducing ageing effects |
abstract |
A method is provided for adjusting the resonant frequency of an aluminum plated quartz resonator so as to reduce the effect of aging. The method comprises initially forming the aluminum plated resonator so that its frequency is above the nominal frequency, and then reducing the frequency to the nominal value by anodically forming an oxide film with a thickness in excess of 50A on the aluminum plating. |
