Silver plated connection

Dears,
My question is about connection between Three layers of copper as following
silver copper plated + pure copper + silver copper plated

Is this connection considered silvered connection surfaces? And what is the difference between this connection & another case that have Three layers are silver plated.

Many thanks in advance

Hi, Mokhtar. Please rephrase or expand upon your question by explaining your own situation, rather than posting an abstract question, because I don't understand it. But if you are asking whether you can omit the silver plating from one piece of copper because it is surrounded by two silver plated pieces, the answer is no: the unplated copper can grow electrically resistive corrosion products on it.

Regards,
