1.lead-free solder bar,low melting point, 2.good fluidity and invasive ability, 3.good thermal fatigue resistance

information of the lead-free solder bar

               

SAC solder has good wet ability and the thermal fatigue

resistance, and is used by many more customers beacuse of its

superior use and soldering performance, but the utilization cost

is higher.

advantages:

1.has extremely high reliability,good mechanical properties and

thermal fatigue resistance after soldering

2.a relatively low melting point

3.good fluidity and excellent soldering performance

4.reduce the corrosion to copper

5.a very good oxidation resistance ability,low production of tin

slag

range of the application:

widely used in lead-free automatic wave soldering, applicable to

mix sudstance or the general wave soldering.

Solder sometimes in is metal alloy used to join together metal workpieces and having a melting point below that of the workpiece(s).

Soft solder is typically thought of when solder or soldering is mentioned, with a typical melting range of 90 to 450 °C (190 to 840 °F). [3] It is commonly used in electronics, plumbing, and assembly of sheet metal parts. Manual soldering uses a soldering iron or soldering gun. Alloys that melt between 180 and 190 °C (360 and 370 °F) are the most commonly used. Soldering performed using alloys with melting point above 450 °C (840 °F) is called 'hard soldering', 'silver soldering', or brazing.
