SCS7, an enhanced Tin-Copper lead free alloy, is highly recommended to directly replace existing Sn/Cu0.7 solders in the high temperature wave soldering applications.

This alloy not only exhibits the excellent ductility of Sn/Cu0.7 solder, it possesses superior mechanical strength both in ambient and high temperature environments. SCS7's fatigue resistance is now comparable to Tin-Lead solder and as such, SCS7 has addressed the fundamental concerns of SnCu alloys.

Besides, it offers benefits of low drossing and good wettability. Its applications cover wave soldering, dipping processes, manual / auto soldering and solder joints touch up using solder wires. This cost effective alloy has been designed to meet the most stringent requirements of the electronics industries.

For wave soldering applications, the solder can be used at 250 ~ 260 °C, depending on PCB design & complexity. Conveyor speed can be set up to a maximum of 1.8m/min for single-sided boards and recommended to set at between 1.2m/min to 1.6m/min for double-sided boards. Recommended preheat temperature is 90 ~ 120 °C on-board, dependent on flux activation temperature, machine design and board complexity.

For dipping, it is recommended to use at temperatures >260°C, depending on applications.
