Conductive silver epoxy is an electrical Conducting Epoxy that gets its conduction properties through the use of metallic flakes. As opposed to traditional soldering, conductive epoxy functions without heat.
Copper, tin, and gold flakes are utilised as well as silver flakes, but silver will be the most preferable one of any. It is naturally heat tolerant and also the most conductive of the other metals.
Among heat tolerance and conductivity, what other positive aspects are there?
• Relative flexibility during the numerous phases of thermal expansion the substrates might experience. Silver epoxy won't break its bond like a traditional solder will when stressed by variances in temperature.
• The curing temperature for conduction epoxy, whether it is silver or every other alloy, is substantially lower as opposed to traditional lead solder.
• Silver filled epoxy isn't just a excellent conductor, it's got superior electrical conductivity as in comparison to every other alloy.
• When the right circumstances present themselves, silver will oxidize just like tin and lead. Where they differ is the fact that silver oxides carry on to stay conductive leading to much less degradation in the network.
• In the instance of oxidation, the shear strength in the adhesive bond is impacted little, if at all.
Just like anything you are able to think of, you can find drawbacks to silver filled conductive epoxy. What would be the drawbacks?
• Silver is a noble metal; as a result when silver epoxy is utilised it must only be utilised to affix two noble metals. (e.g. palladium, silver, platinum, and gold to name a few).
• Cost can be a major deterrent. Silver alone is a precious metal. Being that it cannot be effortlessly utilised with non noble metals, which are relatively pricey in their own right, each substrates must be noble metals, further rising the price of the process.
• Variances within the mixture. Adhesive suppliers provide an exact product for you to mix, but here in lies the rub, you must blend it your self. While the manufactures have taken into account that people rarely do anything to an exact measure, only so much latitude can be afforded within a chemical reaction.
There are some other drawbacks, but as high as the demand is for electrically conductive epoxy, producers are conquering these drawbacks via substantial research and development.
