Ditto - almost. My operating position is a homebrew 72"x36"
desk w/ 72"x18" shelf. Under the shelf is a 72" x 6" back,
made from 3/4" plywood (w/ 2" open space above & below to
allow cables and airflow). A 6" wide strip of aluminum sheet
spans the inside surface and is attached to the shelf back
with a few wood screws. Copper would also work but, I had
aluminum on hand.
I make connection to it using machine screws and _TEE NUTS_.
Where I want a connection, I drill a hole to accept a Tee
nut, and press it into the back using a C-clamp. Then, the
connection can be made using only a capscrew, as tight as
you like.

I too prefer through bolting more than tapping holes in thin
soft materials, copper or aluminum. If you really tighten a
fastener in soft aluminum or copper, then 3 threads are not
enough. Through bolting with stainless steel will let you
tighten thoroughly.
