How to choose the right crystal oscillator?

Coating technology is changing with each passing day. For coating engineers, it is really not easy to choose a good crystal oscillator according to different coating processes. The following suggestions for your reference: 1) When plating low-stress film materials, the common coatings for gold-plated crystal vibrators are Al, Au, Ag and Cu. These films have almost no stress and can be coated at room temperature. The film is soft and easy to scratch, but it will not crack or have a negative effect on the substrate. It is recommended to use gold-plated crystal oscillator for the above coating. Experience has proved that gold-plated crystal oscillator can be plated with 60000 angstroms of gold and 50000 angstroms of silver.
