It is conventional to seed printed circuit boards with a seeder which includes palladium chloride and stannous chloride. Normally, a concentrate of the palladium chloride and stannous chloride is formulated in hydrochloric acid and then an appropriate amount of this concentrate is used to make a new seeder bath, or added to enrich a bath already in use.
