Yes the circuit boards are made with gold, platinum & palladium. Used due to their resistance to oxidization and corrosion. Many of the circuit boards we have were made in the late 1980s liberally using platinum & palladium (approx. $130 per ounce) instead of gold which was (approx. $300 per ounce). Now approx. 20 years later – June 2008, platinum is over $2000 per ounce and palladium was recently over $1800 per ounce & gold is a mire $1000.
