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.
