A technique for spray dicing plated heat sink wafers and implemented on the production line, and details are described in the report. Dice quality is improved, and cost for volume production is reduced with this approach. Results of several diode lots produced to establish tolerances on the wafer parameters are summarized in the report. Further development work on the RF burn-in system is described which was necessitated by problems encountered with low voltage Ku-band diodes. The second life test was completed with no diode failures. Results of the third engineering samples show improved performance with operating frequency for the Ku-band diodes the only remaining problem. Author
