product advantage
Generally we request the customer to provide the center frequency,
type of cutting angle(AT/BT), holder or package type,
resistance(ESR), frequency tolerance, frequency stability, load
capacitance, operating temperature, drive power, aging, etc,
Customer can also specify other specific spec or requirement, if
any, when placing orders.
The new Tianyuan in R & D, design, manufacturing, marketing and
service as a whole, have a hundred grade purification workshop. The
international advanced automated production lines, special test
equipment, the latest technology and professional and technical
personnel; has been preparing for the new Tianyuan own industrial
park, to further expand the research and production of the higher
requirements of the product.
product features
Operating Temperature Range:-40℃~85℃
Crystal Frequency & Resistance will be tested under the following
conditions,
Unless extra requirments:
standard temperature(25±2℃) after heat balance.
Storage Temperature Range:-40℃~+85℃
Mechanical property test:
The test can be measured after 1 hours of rest at the reference
temperature
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:
The Units are measured for its frequency and resistance in
accordance with Table 1&without mechanical damage afer
subjectiong to 2hrs of vibration with 0.75mm amplitude with 10~55Hz
frequency sweep 20 times.
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.
