PROCESSING INSTRUCTIONS
石英晶體意外跌落 When dropped by mistake
設計和製造的石英晶體本身具有耐衝擊能力,但是當石英晶體元件經受劇烈的機械衝擊,如跌落到
1
地板上或安裝期間劇烈震動時,在使用之前需要進行電性能確認
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)使用電烙鐵焊接時,引線應該在 4 秒內焊接完畢,
電烙鐵溫度不能高於 350℃Lead wires should be
soldered within 4 seconds with the soldering iron heated to a temperature no higher than 350℃
(2)使用浸錫方式焊接時,引線應該在 10 秒內焊接完畢,焊錫溫度不能高於 260℃,並且注意不能
將整個晶體浸錫.推薦使用垂直安裝方式,避免熱力直接傳導到晶體上 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.
(3)使用波峰焊接时,请参照下面的波峰焊温度曲线 The WAVE SOLDERING PROFILE as below is
recommended for TDXLF-308 tuning fork crystal re so n a t e rs.

石英晶體彎腳 TO BEND THE LEAD of cylinder type products
(1)當圓柱狀晶體元件需要彎腳時,爲了防止彎腳時造成密封玻璃體的破裂,從彎腳處到晶體基座底
部距離應大於 1.5mm。推薦距離 3.0mm,並使用工裝夾具進行彎腳。When the lead of cylinder type
3
crystal units need to be bent,leave more than 1.5mm(3.0mm is recommendable) of lead from the case 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)當圓柱狀晶體元件進行彎腳時,不要剝離引線的鍍層 When bending the
lead of cylinder type
crystal units,do not scrape off the soldering plating from the lead surface.
元件的安裝 MOUNTING
(1)爲了避免影響元件電性能或損壞元件,嚴禁將圓柱狀晶體元件外殼焊接在印製板上進行固定。
推薦使用橡膠粘結劑進行固定 Soldering the body of the cylinder type crystal units with PCB must be
4
(2)當用手工來彎曲引線時,請遵照下列方法 When the lead needs to be bent by hand,please follow the
instruction as below:用手指捏住圓柱晶體的外殼;用鑷子夾住引線要彎曲的部位,該部位離晶體基座
底部 1.5mm 以上(推薦 3.0mm);用鑷子夾住彎曲引線成 90°,不要用力拉引線。用力拉引線可能
造成引線根部的玻璃子破裂,而産生漏氣損壞元件電性能。Hold the body of the cylinder type crystal
unit in fingers;Pick at the part with twee z er,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 twee z er 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.
石英晶體元件的清洗 CLEANING
(1)惡劣的超聲波清洗或超聲波焊接可能會影響和損壞石英晶體元件。如果您對晶體元件進行了超聲
波清洗,請一定在使用前確認晶體元件是否受到了影響和損壞 Crystal units may be sf f c ted and
5
destroyed at worst by supersonic cleaning or supersonic welding.Please be sure to check if your cleaning
and welding process sf f e c ts any damage to crystal units before using.
(2)有些清洗液也可能造成晶體元件的損壞,請在使用清洗液前確認該清洗液是否適用 Some kinds of
cleaning fluid may cause any damage to crystal units.Please be sure to check suitability of the cleaning
fluid in advance
貯存 STORAGE
石英晶體元件長時間貯存在高溫或高濕環境中,可能會影響頻率的穩定性或可焊性。請將晶體元件
6
貯存在正常的溫度和濕度環境中,避免陽光直射和露水凝結,避免貯存 6 個月以上再使用,拆封後
儘快裝配使用。Storage of crystal units under higher temperature or high humidity for a long term may
affects frequency stability or sold era b i y .Please store the crystal units under the normal temperature and
humidity without exposing to direct sunlight and dew condensation
