Eutectic vs. Non-eutectic Solder Alloys
Every alloy has both a solidus and a liquidus melting temperature. The solidus temperature is the point when the alloy just starts to melt. ...

What is an Alloy?
An alloy is comprised of two or more metals. These metals are stable and have some level of solubility together; otherwise, they would not form ...
What Is A Solder Alloy's 'Liquidus'?
The liquidus of an alloy is the temperature above which the alloy is completely liquid....
What Is A Solder Alloy's "Solidus"?
The solidus of a solder alloy is the temperature above which the alloy begins to melt, and, below which is completely solid....
Solder Technology Inside A Hot Car On A Sunny Summer Day
Here’s a true story regarding the service temperature of solder joints. Yesterday, as I left work, I noticed that it felt really hot outside. I ...
Power and High Temperature Electronics Manufacturing Experience at SMTAI
I am happy to announce that Indium Corporation will participate in the Power and...
Zero Stress Point Temperature for Bonding
At the SVC (Society of Vacuum Coaters) conference this year, I spoke about setting a “zero stress” temperature during target bonding. I&rs...
Optimize the Zero Stress Point
An important quote from Eliminating Bond Stresses of Sputtering Targets at Operating Temperatures is: “This suggests that a target bonded at one...
A Variable Zero Stress Point
We have observed that the temperature at which two materials are bonded will set the base temperature that any subsequent CTE is measured from. T...
Reversing the Effects of CTE Mismatch
Coefficient of Thermal Expansion (CTE) differences between materials can really cause problems when those materials are rigidly bonded. If you’v...
An Alternative Approach to Sputtering Target Bonding
A traditionally bonded sputtering target experiences a wide range of temperatures over its life cycle. It is bonded at over 200°C – usually ...
The Perfect Sputtering Target Bond
Why do we care so much about target bonding? This is important because a sputtering target that truly performs will allow greater process flexibility,...
High Temperature (Braze Alloy) Sputtering Target Bonding, with NanoFoil®
In an earlier post I mentioned one of the presentations we gave at the 2013 SVC TechCon. The other presentation that our team delivered at t...
Eliminating the Bond Stress of Sputtering Targets at Operating Temperatures
For anyone who couldn’t make it to the 2013 SVC, just email me at jhisert@indium.com and I can make sure you receive a copy of “Eliminatin...
Time Required for Refrigerated Flux and Solder Paste to Reach Room Temperature
One question that I often hear from customers is; “Once out of the refrigerator, how long do I have to wait to allow my solder paste and/or flux...
How Low is Low Temperature in Soldering?
Do you ever have a need for a “low temperature” solder (meaning an alloy that melts at less than 175C)? You may have delicate components t...
