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


 5℃~40℃ Storage Temperature is only for the product itself, the temperature for the packing material  is 5℃~40℃.


Recommended Conditions for Manual Welding


Max. Temperature: 350 ± 10 ℃, Time: 3 sec max, Re-solder times: twice max.
