Product features

The precision of the crystal varies greatly within the range of temperature, which will slow the clock (in some cases make the clock faster). For the most electronic applications, the RTC with the 32.768kHz tuning fork is the standard time reference. RTC determines the time and date by the second count, which requires a clock signal of the 1Hz from the 32.768kHz crystal oscillator. The current time and date are stored in a set of registers and accessed through a communication interface.

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:
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.

Product application

32.768K is the base frequency of a clock, 32768 equals 2 of the 15 times. So basically there's a computer phone camera, and the products with timing functions are used to this 32.768K.
