<p>[QUOTE=&quot;fatima, post: 1257294, member: 22143&quot;]There is little to no silver used in electronics though I&#039;ve heard this said many times on this forum.&nbsp; The predominate solder used in electronic printed circuit card production is a mixture of tin/lead.&nbsp; They don&#039;t use silver solder and doing so would cause of number of production issues.&nbsp; (it doesn&#039;t &quot;wet&quot; properly)&nbsp; &nbsp;&nbsp; Furthermore, if any PMs are used at all in a device it will be gold.&nbsp; The reason for gold isn&#039;t for its conductivity, but rather that it does not corrode/tarnish when exposed to air.&nbsp; Tarnish &amp; Corrosion are resistant to electron flow.&nbsp; (conductivity falls)&nbsp; This is an issue with silver which is why you don&#039;t see silver connectors being used in electronic circuits.&nbsp; &nbsp; </p><p><br /></p><p>Because gold has gotten so expensive, there has been a cottage industry built up where the tiny amounts of gold are recovered from sacks of old electronic chips especially microprocessors.&nbsp; There is no similar industry for silver.[/QUOTE]</p><p><br /></p>
