This newsletter outlines efforts to develop alternate cleaning solutions to conventional CFC and CHC based solvents for the cleaning of electrical and mechanical assemblies. Material compatibility is a primary concern. Testing results with copper substrates and Pb-Sn eutectic solder are presented. A novel sensor for monitoring the organic concentrations in copper plating baths is also described. Measurements are made in real time and the probe is small enough to be placed in the bath without disturbing the plating process. Longer intervals between bath cleanup and extended bath lifetimes will result.
