Details About Conductive Silver Epoxy

0

Conductive silver epoxy is an electrical Conducting Epoxy that gets its conduction properties through the use of metal flakes. Unlike standard soldering, conductive epoxy functions with out heat.

Copper, tin, and gold flakes are utilized as well as silver flakes, but silver is the most preferable one of any. It’s naturally heat tolerant and the most conductive of the other metals.

Among heat tolerance and conductivity, what other positive aspects are there?

• Relative flexibility throughout the different stages of thermal expansion the substrates may experience. Silver epoxy will not break its bond like a standard solder will when stressed by variances in temperature.

• The curing temperature for conduction epoxy, be it silver or some other alloy, is drastically lower than the standard lead solder.

• Silver filled epoxy is not just a excellent conductor, it has outstanding electrical conductivity as compared to almost every other alloy.

• When the perfect circumstances present themselves, silver will oxidize just like tin and lead. Where they differ is the fact that silver oxides continue to remain conductive leading to less degradation in the network.

• In the instance of oxidation, the shear strength in the adhesive bond is affected little, if at all.

Just like anything you can think of, there are disadvantages to silver filled conductive epoxy. What would be the disadvantages?

• Silver is a noble metal; therefore when silver epoxy is utilized it ought to only be utilized to join two noble metals. (e.g. palladium, silver, platinum, and gold to name a few).

• Cost can be a significant deterrent. Silver by itself is a precious metal. Being that it cannot be effortlessly utilized with non noble metals, that are somewhat expensive in their own right, each substrates should be noble metals, further escalating the price of the process.

• Variances in the mixture. Adhesive suppliers provide an precise product for you to combine, but here in lies the rub, you will need to mix it yourself. While the manufactures have taken into consideration that people rarely do anything to an precise measure, only so much latitude may be afforded within a chemical reaction.

There are a few other disadvantages, but as high as the demand is for electrically conductive epoxy, producers are overcoming these disadvantages via comprehensive research and development.
