Response to RoHS directive:Our products are RoHS compliance.
7. 推荐焊接工艺 Recommended Soldering Technologies
7.1回流焊 Re-flowing Profile
7.1.1 预热不足有可能引发产品表面裂纹,从而导致产品品质下降。预热温度与最高温度之间的差值应≤100°C。
Un-enough pre-heating may cause cracks on the ferrite, resulting in the deterioration of product quality. The
difference between the preheating temperature and the maximum temperature should be less than 100 °C
7.1.2 不建议将元件浸泡溶剂或使用其他方法来快速冷却元件。
Rapid cooling by dipping in solvent or by other means isnot recommended.
7.1.3 回流焊接条件Reflow Soldering Conditions
预热条件: 150 ~ 200℃/ 60 ~ 120秒
Preheat condition: 150 ~200℃/60~120sec
允许大于217℃时间: 60ー90秒
Allowed time above 217℃: 60~90sec
最大温度: 260 ℃
max temp: 260 ℃
最高温的最大时间:10秒
max time at max temp: 10 sec
焊膏: Sn/3.0Ag/0.5Cu
Solder paste: Sn/3.0Ag/0.5Cu
回流焊次数:最多2次
Allowed Reflow time: 2x max
注意:上表中回流焊曲线仅谨作参考,并非为指定的回流焊工艺。实际的电路板组装配置必须根据客户的具体电
路板设计、焊膏和工艺,并且不应超过以上回流焊曲线参数。
Note: The reflow profile in the above table is for reference only and is not the specified reflow process. Actual board
assembly configuration must be based on the customer’s specific board design, solder paste and process, and should
not exceed the parameters as the reflow profile shows.
