F Reflow soldering Notice: 1、Using the infrared lamp at soldering process may cause uneven temperature rise on plastic surface of the parts,so that please keep the package temperature within left conditions. 2、DO NOT dip the plastic part into solder HuBei TKD Electronic Technology Co.,LTD 湖北泰晶电子科技股份有限公司 Page 7 of 9 10. Handling Notice for Standard Tuning Fork Crystal (Cylindrical Type) 10.1. 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. 10.2. 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. 10.3 Solder heat resistance Please review the condition or consult us about flow solder process. Our soldering condition is under 260ºC within 10sec . 10.4. Mounting metho 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 HuBei TKD Electronic Technology Co.,LTD 湖北泰晶电子科技股份有限公司 Page 8 of 9 elasticity glue (Silicon etc) as shown in below figure. Please don’t gluing hermetic seal grass. 10.5.Ultrasonic cleaning and ultrasonic soldering Soldered by ultrasonic cannot be guaranteed, because crystal may be sympathetic vibrated and may damage. Please study at your side about ultrasonic cleaning. 10.6. 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. 10.7.Solder paste should be more than 150μm thickness. 10.8.Storage environment 10.8.1 To storage the reel at +15℃ to +35℃,25%RH to 65%RH of Humidity. 10.8.2 To open the packing just before using. 10.8.3 Not to expose the sun. 10.8.4 Not to storage with some erosive chemicals. 10.8.5 Nothing is allowed to put on the reel or carton to prevent mechanical damage. HuBei TKD Electronic Technology Co.,LTD 湖北泰晶电子科技股份有限公司 Page 9 of 9 11.PACKING
