Alternative to Lead-based Solders
Defect-free assembly demands choosing the proper materials and equipment to provide maximu control of the process. Many factors should be considered when implementing lead-free alloys to the electronics products such as manufacturability, availability, reliability, and cost.
Health risk aslo should be considered when selecting alternative materials.

Alternatives to Lead in Solder
Element

Potential
Antimony (Sb)
Very toxic, not to be considered
Bismuth (Bi)
Considered OK
Cadmium (Cd)
Very toxic, not to be considered
Copper (Cu)
Low risk, can be used in small amount
Silver (Ag)
Low risk, can be used in small amount
Aluminum (Al)
Very low risk, can be used in small amount
Tin (Sn)
Found in human diet, but large amounts are toxic
Zinc (Zn)
Found in human diet, but large amounts are toxic

Lead is well know as a health risk. Often though, alternatives to Sn/Pb alloys also contain potential harmful elements.

One of the most promising replacement alloys that are currently on the market and very low in the health risk is Sn/Zn/Al alloy.

This new lead-free soldering material (U.S. Patent No. US 6361.626) is now available in North America and around the world for SMT and BGA packaging processes, and other soldering needs.


Innovative Product Technology

Our advance research group provides solder products that make your applications simple, yet high yields and low cost.

 



Although each of lead-free alloys has its advantages and disadvantages, Sn/Zn/Al alloy clearly stands as likely replacement for lead-based solders for the majority of soldering applications.
