Procedure
The electrolessly copper-plated test pieces were immersed in 10% sulfuric acid for 30 seconds, immersed in an electric copper plating bath containing in 1 liter thereof 75 g of CuSO4.H2O, 180 g of sulfuric acid, 0.125 ml of 35% hydrochloric acid and 5 ml of Cu-Brite TH, a brightener produced by EBARA-UDYLITE, copper electroplated at a current density of 3A/dm2 for about 1 hour to a thick thickness of copper of about 35 micrometers, and then water washed with deionized water for 1 minute.
