r most situations is 24 C (75 F) with a range of 21 to 27 C (70 to 80 F). Low temperatures may cause burning.
FUNCTION OF BATH COMPONENTS
Copper Sulfate Content
Copper sulfate provides copper ions for the deposition process. It should be maintained within the specified limits of 55 to 75 g/L. Higher levels give no advantage at 30 ASF but may help increase leveling at higher current densities. Lower concentrations will reduce maximum operating current density but can give improved metal distri
