Conductive Epoxy With Silver Has Unique Positive Aspects
Conductive silver epoxy is an electrical <b><a href="http://www.instantca.com/Resource/ConductiveEpoxy.aspx" target='_blank'>Conducting Epoxy</a></b> that gets its conduction properties through the use of metallic flakes. In contrast to traditional soldering, conductive epoxy works without having heat.<br><br>Copper, tin, and gold flakes are utilised as well as silver flakes, but silver is the most preferable one of any. It is naturally heat tolerant as well as the most conductive of the other metals.<br><br>Among heat tolerance and conductivity, what other benefits are there?<br><br><br><br>• Relative flexibility throughout the various phases of thermal expansion the substrates might encounter. Silver epoxy will not break its bond like a traditional solder will when stressed by variances in temperature.<br><br>• The curing temperature for conduction epoxy, be it silver or some other alloy, is drastically lower compared to traditional lead solder.<br><br>• Silver filled epoxy isn't just a great conductor, it's got outstanding electrical conductivity as in comparison to almost every other alloy.<br><br>• When the ideal conditions present themselves, silver will oxidize just like tin and lead. Where they differ is that silver oxides carry on to stay conductive resulting in less degradation in the network.<br><br>• In the instance of oxidation, the shear strength in the adhesive bond is affected little, if at all.<br><br>Just like anything you are able to think of, you will find disadvantages to silver filled conductive epoxy. What are the disadvantages?<br><br>• Silver is a noble metal; consequently when silver epoxy is utilised it must only be utilised to join two noble metals. (e.g. palladium, silver, platinum, and gold to name a few).<br><br>• Cost is a major deterrent. Silver by itself is a precious metal. Being that it cannot be easily utilised with non noble metals, that are relatively expensive in their own right, both substrates should be noble metals, further rising the cost of the process. <br><br>• Variances in the mixture. Adhesive suppliers provide an precise product for you to mix, but here in lies the rub, you need to combine it yourself. While the manufactures have taken into account that humans rarely do anything to an precise measure, only so much latitude can be afforded in a chemical reaction.<br><br>There are a few other disadvantages, but as high as the demand is for electrically conductive epoxy, manufacturers are conquering these disadvantages via substantial research and development.<br><br>For more information about Adhesive System’s epoxy adhesives or any other <b><a href="http://www.instantca.com/" target='_blank'>Glue Manufacturers</a></b> please contact us at 877.740.1250 x20.
