As to conditions, which are not indicated in this specification and unpredictable such as applied condition and oscillation margin, please check them beforehand. 7.2 Unless we receive request for modification within 3 weeks from the issue date of this NDK specification sheet, we will supply products according to this specification. Also, if you’d like to modify specification of order, which has been placed with delivery request within 3 weeks from the issue data of this specification sheet, we would like to discuss with you separately. 7.3 In no event shall the company be liable for any product failure resulting from an inappropriate handling or operation of the product beyond the scope of its guarantee. 7.4 Where any change to the process condition is made due to the change(s) in the production line, inform personnel of the specifications. 7.5 Should this specification data give rise to any disputes relating to any intellectual property rights or any other rights of a third person, the company shall not indemnify anyone for any damage. Their disclosure must not be construed as the grant of a license to use any of the intellectual property rights owned by the company. 7.6 If you intend to use products listed on this specification for applications that may result in loss of life or assets (controls relating to safety, medical equipment, aeronautical equipment, space equipment, etc.), please do not fail to advise us of your intention beforehand. 7.7 In the company’s production process whatever amount of ozone depleting substances (ODS) as specified in the Montreal protocol is not used. 7.8 Information contained in this specification must not be quoted, reproduced or used for other purposes including processing either in part or in full without obtaining prior approval from the company. 7.9 Crystal units will be damaged by ultrasonic welding process due to resonance of crystal wafer itself. NDK does not recommend using ultrasonic welding. If Ultra Sonic welding used, NDK strongly recommend verifying crystal unit damage by ultrasonic weld. 7.10 The appearance color has a different case by purchasing it more than 2 suppliers of the component, but characteristic and reliability are guaranteed. 8. Prohibited items Be sure to use the product under the following conditions. Otherwise, the characteristics deterioration or destruction of the product may result. (1) Reflow soldering heat resistance Peak temperature: 265C, 10 sec Heating: 230C or higher, 40 sec Preheating: 150C to 180C, 120 sec Reflow passage times: twice (2) Manual soldering heat resistance Pressing a soldering iron of 400C on the terminal electrode for four seconds (twice).
