Pretty thin stuff- - - -maybe .002" or .003" thick. You can trim it to shape and glue it down, using the shadow on the circuit board at the light socket holes as a pattern. Then glue a piece of bare wire to the board, following the pattern that's there, and tack-solder the wire to the shim stock. I like to use a very high heat soldering gun, (250 watt) and do a quick tack with the gun at max heat. It only takes a couple of seconds to get a good bond. Use rosin core electronic solder, not acid core sheet metal tinners' solder.
