*Also known as Copper(II) chloride, or Cupric chloride<br />
*Formula of CuCl2<br />
*Has many uses, but the main use case to OSE is as an [[Etchant]]<br />
<br />
=Use as an Etchant for PCBs==<br />
*Copper chloride is reusable either by<br />
**Dilution with more hydrocloric acid<br />
**Chemical Reprocessing to remove copper and impurities<br />
*The chemical reprocessing is more simple than other etchants, and it is also easy to reuse via dillution due to the availability, and cost of hydrochloric acid<br />
