Using the Density Technique to Estimate Gold Mass Fractions in Gold Alloys with Silver and Copper
Folks, My second email from Adriana Re using density to determine gold mass fraction is below. She asked if we could communicate in French. The transl...
Calculating the Mass Fraction of Gold in a Gold Alloy
Adriana writes, "Dear Dr. Ron. I’m trying to program the equation for determining the weight fraction of gold in scrap metal from the densi...
Back to Basics: Au-Based Alloys
Indium's “Gold Standard” refers to the overall reliability and quality you can expect from our gold-based solder materials. Gold-based...
Solder in Medical Devices: Wait, There's Solder There?
Shielding the RF waves generated by an MRI machine is mandatory. Soldered copper is one the metals used for RF shielding because it absorbs radio and ...
Solder in Medical Devices: That Solder’s Going Where?
Cardiac pacemakers generally use 99.99% Au preforms as the solder material in the assembly. Pure gold is highly pure, inert, biocompatible, has a high...
What the Off-Eutectic?
Indium Corporation's new off-eutectic alloy preforms ensure strong solder joints in a plethora of device and package hardware. Our off-eutectic Au...
That's a 'Fine' Ribbon You Got There!
Indium Corporation has developed 80Au20Sn < 0.1” wide fine-grade precision ribbon for high volume, fully automated laser diode assembly proce...
Why Do We Need to Go Thinner?
Indium Corporation has developed a thinner gold preform for high-output lasers, therefore improving the thermal transfer and operational efficiency of...
How does AuSn alloy and flux impact the reliability of solder paste?
When looking at the reliability of AuSn solder paste, you need to take a couple of things into consideration, the post reflow alloy composition (off-e...
Why is AuSn powder size important for solder paste application?
Today's electronics continue to get smaller and smaller, so the traditional type 3 (-200/+325) mesh size might be too large for new scale-ups. Thi...
A Precise Equation Relating Karats of Gold to Density in Gold Alloys
Dr. Ron received a question asking him to verify a calculation used to determine the karat value of various gold-based alloys. It's not as si...
