通过研究，选择一种或两种无铅锡膏。
您不需要为更换无铅锡膏而更改钢板设计。
You should not have to change your stencil design to accommodate the change to lead-free.
最明显的是，使用无铅锡膏必须提高回流焊温度。
The most obvious is the necessity for increased reflow temperature.
因此研究无铅锡膏在电子封装中的应用具有重要意义。
So study lead-free solder paste in the electronic application package is important.
本文结合公司的生产实际，对无铅锡膏和无铅焊接工艺进行了系统研究。
This paper's actual production of lead-free solder paste and lead-free soldering process has been systematically studied.
实验表明，无铅锡膏在钢网上的流动性很差，导致沉积面积，体积和高度的最大值和最小值的波动变化十分明显；
Experimental results show that lead-free solder paste in the poor mobility of steel line, resulting in deposition area, volume and height of the maximum and minimum fluctuation is obvious;
主要产品有：焊锡丝、焊锡条、无铅锡线、无铅锡条、锡膏、锡锭、助焊剂、电镀阳极棒、巴氏合金等。
The main products are: solder wire, lead-free solder bar, line, lead-free solder paste, strips, tin ingots, flux, electroplating anode, babbitt, etc.
三种焊锡膏均可形成饱满、光亮的焊点，锡铅焊点外观比无铅焊点更规整圆滑。
All of the three solder pastes could form plump and splendid solder point, and the appearance of Sn-Pb solder point was more regular and sleek.
回收废锡料：无铅焊锡回收、锡渣回收、锡条回收、锡线回收、锡膏回收、锡灰等废锡废铅回收。
Recycling waste tin material: lead-free solder recovery and recycling, tin tin slag the recycling, tin line recovery, solder paste recycling waste tin tin ash, such as waste lead recovery.
本公司生产的有铅锡膏已采用符合无铅要求的助焊膏。
Soldering flux meeting the lead-free requirements is used for the lead-containing solder paste manufactured by our company.
