tuning fork crystal - handling note for through hole type
1. mounting: • if the crystal is mounted on board directly (orientation: lay down) or fixed by metal parts, the body of the crystal will be heated up • recommended mounting:

• ultrasonic cleaning with organic solvents • ultrasonic frequency should not be equal to the resonance frequency of the crystal • handle the crystal carefully, it cannot stand heavy shock • if you test the whole board automatically do not apply pulse to the crystal oscillator circuit, especially high pulse level can break the crystal blank
