Finishing coating: immersion silver
Immersion silver (Imm Ag) is a special type of finishing coating resulting from the precipitation of a thin silver layer on a copper surface of the contact areas. It is suitable for the production and assembly of prototypes/serial batches of microwave products.
Forming a special silver-tin-lead alloy on the copper layer during the soldering process, the material allows to make reliable connections for BGA components. Features: high surface conductivity and no nickel.
