This new electroplating method of gilding was much cheaper, easier and safer than the old mercury gilding process, even if the results were somewhat inferior. As a result, gold electroplating rapidly displaced the superior fire gilding process starting in the 1840s.
Removing the Gold Gold can be removed from circuit boards in a variety of ways. It can be scraped off of the boards by hand, which is time consuming, but yields excellent results. The gold can also be removed via a process known as reverse electroplating, where a chemical solution and electricity are used to draw the gold off of the circuit board.
