In recent days, one of my fellow applications engineers, Jim Hisert posted a blog on his semiconductor website about indium bonding and indium cold welding. This is a topic that comes up often both in the semiconductor world as well as the thermal interface material world.

In semiconductors, I believe the most common application for the indium bonding process is cold welding low temperature indium flip chip bumps to an indium substrate. In the thermal interface material world I commonly discuss this topic with engineers who want to use it to achieve a void-free, high reliable thermal interface material and solder TIMs are out of the question because these require the use of a flux.

For more information on the topic of indium bonding and indium cold welding, read through Jim's blog.

Comments for Indium Bonding and Indium Cold Welding

Tuesday, May 12, 2009 by Leslie:: It is important to remember to use proper eye protection. Be sure the light from an arc welder can’t get in. Its very painful to burn your corneas and the pain may not start for hours after the injury.
Wednesday, May 13, 2009 by Amanda Hartnett:: Leslie, That is a great point- It is always a good idea to use proper safety precautions. However, the process of cold welding indium does not require the use of an arc welder. Cold welding implies that no heat is used. Still, the process may include acid, which has its own safety precautions.
