provided by the clock generator, clock generator, clock circuit is
the core of the motherboard, the motherboard. The motherboard as
the heart of the crystal main clock oscillator, crystal oscillator
and real-time sound card, NIC crystal.
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.
