Defining steaming conditions for a thin metal film electrode for the new SC cut crystal unit

In order to obtain fine contacts over the crystal unit, it is necessary to apply a thin layer of metal electrodes on its surface. The structure of the thin metal film formed by evaporation and condensation under the vacuum depends on many parameters and therefore it is very important to define the terms of steaming. This paper describes a method for achieving a good structure of thin metal films in high quality crystal units with SC cuts, which are designed for high quality OCXO oscillators.
