石英晶振使用说明书
PROCESSING INSTRUCTIONS
■
石英晶体意外跌落(When dropped by mistake)
设计和制造的石英晶体本身具有耐冲击能力,但是当石英晶体元件经受
剧烈的机械冲击.如跌落到地板上或安装期间剧烈震动时,在使用之前需
要进行电性能确认.
The crystal units are designed and manufactured to resist physical shocks. However, When
the crystal units are subjected to excessive impact such as being dropped onto the floor or
giving shocks during processing .need to make sure its satisfactory performance before
using it.
■
焊接(Soldering)
(1) 引线型产品(Lead Type products)
① 使用电烙铁焊接时,引线应该在 3 秒内焊接完毕,电烙铁温度不
能高于 300℃
Lead wires should be soldered within 3 seconds with the soldering iron
heated to a temperature no higher than 300℃’
② 使用浸锡方式焊接时,引线应该在 10 秒内焊接完毕,焊锡温度不
能高于 260℃,并且注意不能将整个晶体浸锡,推荐使用垂直安
装方式,避免热力直接传导到晶体上.
In solder-dip processing,the leads should be soldered within 10 seconds
with a temperature no higher than 260℃.Mounting in upright is
recommendable to prevent the heat conduction directly to the body of the
crystal unit.
■
石英晶体剪脚(To bend the lead of cylinder type products)
① 当圆柱状晶体组件需要剪脚时,为了防止剪脚时造成 密封玻璃体的
破裂,从剪脚处到晶体基座底部距离应该大于 1.5mm,推荐距离 3.0mm,
并使用工装夹具进行剪脚.
When the lead of cylinder type crystal units need to be bent ,leave more
than 1.5mm(3.0mm is recommendable) of lead from thecase
in order to
prevent from any cracks of the hermetic sealing glass at the root of the
lead ,and use a jig to bend if possible.
② 当圆柱状晶体组件进行剪脚时,不要剥离引线的镀层.
When bending the lead of cylinder type crystal units,do not scrape off
the soldering off the soldering plating from the lead surface.

元件的安装(Mounting)
■
圆柱状晶体元件的安装 Mounting of cylinder type products
① 为了避免影响元件电性能或损坏元件,严禁将圆柱状晶体元件外壳焊
接在印制板上进行固定,推荐使用橡胶粘结剂进行固定.
Soldering the body of the cylinder type crystal units with PCB must be
avoided due to deteriorate the characteristics or damage the
products.Rubber adhesive is recommended.
② 当用手工来弯曲引线时,请遵照下列方法.
When the lead needs to be bent by hand, please follow the instruction as below:
用手指捏住圆柱晶体的外壳,用镊子夹住引线要弯曲的部位,该部位离
晶体基座底部 1.5mm 以上(推荐 3.0mm);用镊子夹住弯曲引线成 90°,
不要用力拉引线,用力拉引线可能造成引线根部的玻璃珠破裂,而产生
漏气损坏元件电性能.
Hold the body of the cylinder type crystal units in fingers; pick at the part with
tweezer,which you want to bend .there should be more than 1.5mm (3.0mm is
recommended)from the body case.
Bend the lead 90°by tweezer without pulling the lead strongly. If pulling the lead

strongly may cause any cracks of hermetic sealing glass at the root of the lead and may
cause the leakage and the characteristics to deteriorate.
■
石英晶体元件的贮存
石英晶体元件长时间贮存在高温或高湿环境中,可能会影响频率的稳定
性和可焊性,请将晶体组件贮存在正常的温度和湿度环境中,避免阳光直
射和露水凝结,避免贮存 6 个月以上再使用,拆封后尽快装配使用.
Storage of the crystal units under higher temperature of high humidity for a long term may
affects frequency stability or solderability .please store the crystal units under the normal
temperature and humidity without exposing to direct sunlight and dew condensation ,and
avoid the storage of crystal units for more than 6 months ,and mount them as soon as
possible after unpacking.
