Abstract : This report covers the period from 15 October 1994 through 15 January 1995. Our program has initiated test and evaluation of the no lead system, pursued several risk reduction activities, and continued concept design efforts for the copper system. Progress during reporting period: Produced primitive test coupons demonstrating line and single ball capability. Identified and studied problem areas for no lead system reliability including the environmental chamber, nozzle, and material contamination. Designed and installed a new environmental chamber to improve process reliability. Started effort to resolve nozzle problems by working with the vendor concerning orifice surface finish and redesigning orifice holder (nozzle). Implemented new material handling procedures to minimize contamination problems. Continued testing copper melting and construction material compatibility. Completed 60 percent of the conceptual design of the copper system and subsystems. Added a contract engineer for three months to insure continued design progress. (jg) p. 1 + 298
