Switching to semi-aqueous cleaning of printed circuit board assemblies at Raytheon missile divisions

Details of planning and implementing the switch from an ozone depleting chemical used for cleaning of printed circuit board assemblies to a terpene based semi-aqueous process demonstrate that environmentally and economically sound manufacturing methods are achievable in the production of extremely high performance systems. Significant process, product quality, and workforce problems can be overcome with the commitment of top management and persistence of all stakeholders.
