二、合金粉配比

(表1)

三、使用/注意

1、焊膏保存温度在常温5-20℃，勿接近高温处。

2、使用前将焊膏搅拌均匀，倒入合金粉搅拌。

3、搅拌时间根据合金粉份量来定，参考时间:（搅拌机搅拌5-12分钟）.

4、搅拌温度控制20-25℃，在搅拌过程中合金粉磨擦会产生温度会上升，注意观查合金粉变化。

5、手工搅拌要在干燥空气中操作，使用不锈钢材料搅拌。勿使用其它金属成份接触锡膏。

Third, use / attention

1, paste stored at room temperature, the temperature 5-20℃, not to close to heat.
2 Stir before using the paste, stirring into the alloy powder.
3, stirring time under the weight of alloy powder to set, reference time: (Mixer 5-12 minutes).
4, mixing temperature control 20-25℃, the alloy powder in the mixing process will produce friction between the temperature will rise, pay attention to changes in view of investigation alloy powder.
5, hand mixing in dry air to operate, so that stainless steel mixing.Do not use the other metal components contact solder paste.
