Waste minimization study for a printed circuit board manufacturing facility in Taiwan.
Plant audits were conducted on various processes, such as deburring, alkaline etching, black oxidation, desmearing, electroless copper, and copper and tin/lead plating.
Specific areas in which the wastes could be minimized, such as reduction of the amount of dragout and rinse water requirements in the plating and etchant lines and onsite treatment and reuse of spent bath solutions, were identified, assessed, and implemented.
Jar tests on the wastewater were performed, and the results were used to improve the efficiency of the wastewater treatment plant for removal of heavy metals and reduction of sludge generation.
