Crystal oscillator shell-why should crystal use insulation pads?

Crystal oscillator shell manufacturer-why should crystal use insulation pads?

1. The essence of the crystal is made of piezoelectric crystal. The two surface -shaped conductive materials of the sheet should be a wire or contact. The two surfaces are always the opposite charge at work. Hutchison will be "suspended".

2. The crystal should work in a shell that can be "free to vibrate". The crystal crystal is generally welded through the lead.

3. Note: There is a "patch crystal". The shell does not affect the free shock. It can directly contact the two ground -pass pads on the line board.

4. If it is not a "patch crystal", it is not possible to directly contact the two ground -pass pads on the line board.

However, it can be sandwiched between the two conductive electrodes with good elasticity and use it in a non -welding state.
