Solder Alloys

Selecting Solder Alloys

Solder alloys are selected for the following properties:

•Melting point
•Mechanical characteristics
•Wettability
•Abscence of Lead
 
 
 
About Solder
 
•Common solder alloys used in electronics manufacturing:
–tin-lead:Sn63Pb37 (Melting Point 183 Celsius)
–tin-silver-copper:SAC305: Sn96.5Ag3Cu0.5 (Melting Point 218 Celsius)

•Alternative “lead free” alloys include:
–tin-silverSn96Ag4 (Melting Point 221 Celsius)
–tin-copper-nickelSn100C (Melting Point 227 Celsius)
 
Physical Forms of Solder
 
 

•Rosin Core Wire Solder (various sizes and flux types)
 
 
 

•Pre-Forms (custom manufactured)
 
 
 

•Solder Paste (spherical metal particles suspended in flux)

About Us

Advanced Integrated Technologies is essentially a manufacturing service company with two major divisions. The resistance welding and reflow soldering tool division grew out of our early work building micro tools for Hughes Aircraft. About the time that Microsoft was turning computers into a household item, computer hardware manufacturers were looking for companies to build reflow tools used in the assembly of hard drives and other components.
