Because simple copper salts are insoluble at pH above about 4 the use of alkaline plating media necessitates use of a complexing or chelating component Historically complexing agents for electroless copper baths have almost always fallen into one of the 2
This process is required to deposit a thin conductive coating of copper to the fiberglass of the hole wall so that the holes can be subsequently electroplated The thickness of the electroless deposit is typically between 45 and 60 millionths of an inch
Gold Plating Thickness of Connectors and Contacts Proper specification of gold plating thickness for connector and contact applications is a key design consideration Gold plating is an exceptional finish for connectors of that demand both high reliability and durability; however the thickness of the gold plating will impact the durability and ultimate cycle life of the connector

In theory a stainless part passing the copper sulfate test will have no residual copper and will be safe for medical use However the attitude in the industry is that nobody wants to undertake the task of proving this is a reliable certainty therefore ASTM F1089 [affil link to spec at Techstreet] requires that any medical instrument tested with copper sulfate be disposed of

Water Ionizers Vinegar & Citric Acid Washes Water ionizers will generally last about 20 years if you take care of them properly If you use hard water with a water ionizer for that many years though it s likely that you ll need to do at least a few vinegar or citric acid washes in that time The point of a vinegar or citric acid wash is to remove the built up scale inside
In early 2021 Ivanhoe completed a scoping study on the Mount Elliott project a 570 Mt low grade copper gold deposit The study found that the original Mount Elliott underground mine could potentially be mined via an open pit and processed at the Osborne complex and the SWAN higher grade area of the deposit could potentially be progressed to a large scale 12 Mtpa underground block cave mine
Electroless plating is often used to deposit nickel or copper metal onto plastic substrates First the surface of the plastic is etched away using an oxidizing solution Because the surface becomes extremely susceptible to hydrogen bonding as a result of the oxidizing
