Ultrasonic cleaning
General cleaning solutions or ultrasonic cleaning method may be used to clean our products. However, under certain circumstances, ultrasonic cleaning machine could generate resonance at the oscillaton frequency of our products
and thus deteriorate the electrical characteristics in devices, and even damage the overall structure of devices.
Therefore, verification test is recommended before cleaning.
Ultrasonic welding
Avoid mounting and processing by Ultrasonic welding this method has a possibility of an excessive vibration spreading inside the crystal products and becoming the cause of characteristic deterioration and not oscillating.
Storage temperature description
