Send To A Friend Soft Solder Paste

Soft Solder Paste
Solder paste is an alloy or pure metal which, when heated, liquefies and melts to flow onto the space between two close fitting parts, creating a soldered joint. 
Solder paste has suitable melting and flow properties to permit distribution by capillary attraction in properly prepared joints. 
Solder pastes produce joints that meet service requirements, such as strength and corrosion resistance. 

These low temperature flux-binder systems are intended for soldering applications under 450°C / 840°F. 

Suitable heating methods include torch, induction, resistance, infrared, hot plate or oven, and clean-up is easily accomplished with a hot water rinse. 

We have many soft solder paste alloys available with different flux combinations from Fusion Inc.
