Be aware that gold can form insulating compounds when in contact with

Do you have a reference for that? I've not heard it before, so would be
interested to see the details of what kind of insulating layer it may
form with tin, and why.

My chemistry is rubbish, but there's an electrochemical reaction which
takes place at a gold/tin interface which causes corrosion. It's a
well-known problem in computers, when tinned memory sticks are used in
gold-plated sockets, or vice versa.

Ah! 'Click' of connection being made! I *now* recall hearing about this
in the past!

Slainte,
