Here are some things you need to know if you are planning on using liquid metal.
For some reason, I find the combination of gold and indium incredibly interesting. This shouldn’t come as a surprise; I caught gold fever panning for gold during a trip to Alaska, and “indium fever” is a pre-requisite for my job. Well, if it isn’t – it should be.
Low temperature alloys have a number of applications, including step soldering and interconnection of molded components. Additionally, its thermal and electrical conductivity make it attractive for bonding and heat transfer.
