Abstract:
Efforts were continued on the establishment of a production facility with capacity necessary to manufacture a minimum of 35,000 each of 14 watt RC-07 and 12 watt RC-20 resistors per eight 8 hour shift. Reliability testing was completed after one years testing. During the one yrrs reliability load lif testing, only the RC-07 .27 megohm and RC-20 .24 megohm ranges developed a sufficient number of failures to establish a Weibull plot. All other ranges had zero failures except the RC-20 .48 megohm which had one failure. The Weibull plot for the RC-20 .24 megohm and the RC-07 .27 megohn shows a probability of surviving 2000 hours of .96 and .91 respectively. All seven RC-20 ranges were processed and submitted to Pilot Run testing. The first three RC-07 ranges 50 ohm, 10K ohm, and .5 megohm are being screen tested prior to official Pilot Run testing.
