Shock resistance It may deteriorate the characteristics or cause of no oscillation if excess physical shock given. Please be careful not to drop. Please use under condition to minimize the shocks as much as possible. Please review the conditions if it is used by auto mounting or after the conditions are changed. 2. Heat and humidity resistance in storage Storing the crystal products under higher or lower temperature or high humidity for a long period may deteriorate the characteristics of crystal units. Please store and use the crystal products at the normal temperature and humidity. 3. Solder heat resistance Standard type crystal products use Material have a 280℃ melting point. Heating up the package more than 270ºC may deteriorate the characteristics or cause of no oscillation the products. come visit our site http://www.yxc.hk 3/5 YSX146GA/YSX306GA 4. Mounting method to PCB When the crystal products need to be lay down please fix to PCB securely. If the crystal is used with mechanical vibration location, please put cushion in between PCB or fix with elasticity glue (Silicon etc) as shown in below figure. Please don’t gluing hermetic seal grass. Y SX 146G A 1.3 0.6 1.9 0.6 0.3 Y SX 306G A 1.2 5.1 1.9 1.2 1.3 4.2 1.3 5. Ultrasonic cleaning and ultrasonic soldering Soldered by ultrasonic cannot be guaranteed, because crystal maybe sympathetic vibrated and may damage. Please study at your side about ultrasonic cleaning. 6. Drive level Applying excessive drive level to the crystal units may cause deterioration of characteristics or damage. Less then 1.0μW is recommended to this products. More than 2.0μW cannot be guaranteed.
