•  SOLDERING

Please perform the below Reflow conditions to reference within 3 times.

•  MOUNT

Our crystal products are designed to be compatible with automatic mounting. Be sure to have a mounting test in advance by using the actual mounting machine and check that the characteristics of the products are not damaged by the automatic mounting.

In the process where the board is warped, such as board separation process, be careful that the warping does not influence the characteristics and soldering of crystal products.

Since mounting by Ultrasonic welding and processing have a possibility of an excessive vibration spreading inside a crystal resonator and becoming the cause of characteristic deterioration and not oscillating, it does not recommend unless you choose our anti-Ultrasonic crystal products（抗超声波晶振产品）.

Underfilling Material for our crystal products, Genuway Technology considers underfilling material such as heat-cured resin would not affect the characteristics of the crystal mounted, however, we recommend the crystal be tested and checked in such a case prior to use so that there are the possibility that the crystal may have a lid off or a crack in the ceramic base.

•  WASHING

About use of the washing liquid of a basin system, an alcoholic system, and a chlorofluorocarbon-replacing material system, it is checking that it is satisfactory. However, please consult in advance about other washing liquid. Although the check about ultrasonic washing is performed, since it is an examination with a simple substance, the check for the second time by the use state is recommended.

•  THE CAUTIONS ON USE

The crystal unit may be damaged, if excessive excitation electric power is applied. Please use it within the value specified in the specifications.

Please refrain from forming patterns between crystal land patterns since there is a possibility to cause crack in the base.

If the temperature is higher than +280 °C, there is a possibility for the sealing glass to remelt. Avoid using the product at temperature higher than specified.

•  HANDLING OF A CRYSTAL PRODUCT

Genuway Technology crystal product series has sufficient intensity to fall and vibration. However when too much shock is added according to a certain cause, the use after a characteristic check is highly recommended.

•  STORAGE

Since the soldering nature of a terminal may be degraded, please avoid storage in high temperature and/or a humid place. Please keep it in the place where direct rays do not hit and dew condensation does not generate.
