Operating Temperature Range:

-20℃~70℃

Crystal Frequency & Resistance will be tested under the following conditions,

Unless extra requirments:

standard temperature(25±2℃) after heat balance.

Mechanical test:

The quartz crystal unit shall be subjected to normal atmospheric conditions for 1hr before being tested.

Dropping Test:

The Units are measured for its frequency and resistance in accordance with Table1 & without mechanical damage,after allowing the crystal to fall freely.From 75 cm of height 3 times on the firmed wood.

Vibration Test:

A. Test surface: 30mm thick hard board;

B. Drop height: 75cm;

C. Drop times: 3 times;

D. Begins to drop posture: the leading end is upward;

E. Initial and final test items: frequency, resistance

Sealing Tightness:

Find Lead Test:≤1×10^-8atm·cc/S by Helium mass-mass-spectrometer detector,and vacuum and reach 1×10^-3Pa；

Resistance to Soldering Heat:

The Units are measured for its frequency and resistance in accordance with Table 1 after dipping into molten solder with the temperature of 320℃±10℃；For 3~4 secs and at a depth up to a point 2.0mm from the base root.
