Handling Instructions晶振应用指南
Soldering焊接
Our products are designed so they may withstand the same standard reflow soldering temperatures as most other electronics components. However, if the reflow temperature is higher than our specification allows, the performance may be affected. Avoid soldering the product at temperatures higher than specified.
我们的产品经过精心设计，可承受与大多数其他电子元件相同的标准回流焊接温度。但是，如果回流温度高于我们的规范允许，性能可能会受到影响。避免在高于规定的温度下焊接产品。
For the reflow temperature profile of SMD products, refer to Reflow Temperature Profile below:
The reflow temperature profile may vary depending on the product model, specifications and frequency range. Refer to the individual product specifications for details.
根据晶振产品型号、规格和频率范围的不同，回流焊温度曲线可能会有所不同。详情请参阅具体产品规格书相关说明。
SMD贴片式晶振产品的回流焊温度曲线，请参阅回流焊接温度曲线，如下图所示：
Soldering methods for lead type products 引线式/DIP直插晶振产品手焊焊接位置及温度控制说明
针对引线式晶振焊接过程中，请使用平头焊头，对引线部位的加热温度要控制在260°C ~300°C之间，且加热时间要控制在3秒以内。
Cleaning清洁
General cleaning solutions or ultrasonic cleaning may be used to clean our crystal products, but verification tests are recommended prior to use.
一般清洗液或超声波清洗可用于清洗我们的石英晶振产品，但建议在使用前进行验证测试。
Tuning fork crystals resonate at frequency bands that are close to the washing frequency of ultrasonic cleaning machines and this may cause resonance deterioration in the crystal. Therefore the use of ultrasonic cleaning machines to clean tuning fork crystals should be avoided. After applying ultrasonic cleaning, the functionality of crystals should be verified by testing the performance of the end product.
音叉晶振在接近超声波清洗机清洗频率的频带上发生共振，这可能导致晶体共振恶化。因此，应避免使用超声波清洗机清洗音叉晶振。若使用了超声波清洗，应通过测试最终产品的性能来验证晶振的功能及性能是否正常。
Shock机械冲击
Crystal products are designed to resist shock, but if the products receive excessive shocks or are dropped on the ground, be sure to check for any damages before using.
我们在石英晶振产品设计时已包含了抗冲击能力，但如果晶振受到过大物理冲击（包括跌落），在使用前一定要检查其是否遭受损坏。
Mounting安装
SMD crystal products贴片式晶振
Surface mount crystals are designed to be compatible with most automatic mounting processes, but some processes may exert excessive shock which may damage the crystal. Therefore test mounting of the crystal prior to mass production is necessary.
表面贴装晶体的设计与大多数自动安装工艺兼容，但某些工艺可能会产生过大冲击，从而损坏晶振。因此在量产之前，请对晶振进行测试安装。
If there is a possibility that PCB may be warped, make sure the warping is not to such a degree that the crystal products’ operating characteristics or soldering conditions will be negatively affected.
如果PCB可能发生翘曲，请确保翘曲程度不会对晶振产品的工作特性或焊接条件产生负面影响。
Avoid mounting and processing by Ultrasonic welding because this method has a possibility of an excessive vibration spreading inside the crystal products and becoming the cause of characteristic deterioration and not oscillating. If , for some reason, you have no choice but to choose this Ultrasonic welding way, please contact us and we will help choose the crystal products designed for anti- Ultrasonic damage.
请避免用超声波焊接进行安装和加工，因为超声波可能引发晶振特性劣化和/或停振。若一定要选择超声波工艺进行封焊，请联系我司客服，协助您选择我司研发的专门针对过超声波的晶振产品，以降低不良率。
Lead type引线式晶振
When bending, forming, or mounting leaded crystal products be careful not to put too much pressure on the glassed part of the base, as it may crack and negatively affect the crystals’ performance.
在弯曲、成型或安装引线式晶振产品时，请注意不要对基座的玻璃部分施加太大压力，因为这可能会导致玻璃珠开裂，从而对内部石英晶片的性能产生负面影响。
Storage仓储
Storing crystal products at high temperatures or high humidity may deteriorate the soldering condition of pins. Do not store in direct sunlight or damp environments.
储存在高温或高湿度的晶振产品可能会恶化引脚的焊接条件。请勿将晶振产品存放在阳光直射或潮湿的环境中。
Others其它
Crystal Resonators石英晶体谐振器/无源晶振
When excessive voltage is applied to crystal resonators, their performance may be affected or the crystal blank may be damaged. When handling the product, use the product within the specifications provided.
当施加过高电压到石英晶体谐振器时，晶振的性能可能会受到影响或石英晶片可能会损坏。在使用晶振产品时，请勿超出其规格范围。
Negative resistance determines the tolerance margin of a circuit that oscillates the resonator. We recommend that the negative resistance be at least five times the standard series resistance for standard applications, and at least ten times the standard series resistance for automotive and safety applications.
负性阻抗决定振荡谐振器电路的容限。对于标准应用，我们建议负性阻抗至少为等效阻抗的五倍。对于汽车和安全应用，负性阻抗应至少是等效阻抗的十倍。
Crystal Oscillators石英晶体振荡器/有源晶振
C-MOS is used for internal circuit of crystal oscillators. To prevent static electricity, take careful note.
采用CMOS管作为晶体振荡器的内部电路。为了避免静电对有源晶振的破坏，请谨慎操作，全程做好防静电措施。
Some crystal oscillators do not have internally connected bypass capacitors. When using the product, use a capacitor with a good high frequency characteristic of 0.01μ F between Vcc and GND (e.g. Ceramic chip capacitor) and connect it at the shortest possible distance. For details, refer to the specifications of each individual product.
有些石英晶体振荡器没有内部连接的旁路电容。使用有源晶振产品时，请使用Vcc与GND之间高频特性良好的电容器，并以尽可能短的距离连接。有关详细信息，请参阅晶诺威科技有源晶振产品的相应规格书。
Our products are manufactured in a dust-free environment. To keep them clean and dust free, keep them in a clean environment after they are unpacked.
我们的晶振产品在无尘环境下制造完成。为了保持其清洁和无尘，请在打开包装后尽量在洁净环境中完成安装。
