Please don’t be fooled by misconceptions like the following: 1) Lead is bad 2) Soldering is simple 3) Soldering is complex 4) Changing a S...
In a perfect world, materials printed through a circular stencil aperture would be column-like with a flat top. When you look closely at a printed fl...
Why doesn’t my solder flow? The most common issue preventing good solder wetting on a substrate is oxidation. All metals are prone to some level...
We are looking into a way to deposit solder on a typical die attach machine without using die-attach paste – and without a tooling change. This...
Have you ever been so proud of something that you just wanted to go yell out your feelings from a rooftop? Here’s the deal – our spheres ...
At Indium we pride ourselves on Technical Service. If you’re seeing something out of the normal with your soldering materials – please gi...
Soft solders are used instead of hard solders in applications were there are large coefficient of thermal expansion mismatches between semiconductor d...
This question was posed to me while introducing a family member to the world of Engineered Solders this past weekend. While I was still reeling from t...
Spheres are a great solder form for prototype work. (Pictured here are a range of sphere sizes, BGA size compared to flip chip size.) Solder spheres...
Just in case you haven’t heard of epoxy flux yet, let me fill you in. Epoxy flux is what I call a “super no-clean” flux. A no-c...
The shape of your solder joint below a flip-chip or BGA is controlled by the surface tension of the alloy, the activity of flux used, the tension or c...
