PRODUCTION ENGINEERING MEASURE FOR HIGH RELIABILITY, FIXED, FILM, PRECISION RESISTORS.
Abstract
Efforts were continued on the establishment of a PEM for high reliability, fixed, film, precision resistors conforming to the requirements for Minuteman components. Four experiments are discussed in detail. They are Frit Run on Film, Tweezer Marks from Sub-Assembly, Foreign Matter, and Spiral Length. The process data and data summaries are presented. A proposed program is presented for the 1710 computer. Design of the sub-assembly machine is virtually complete. Design of the termination inspection machine is complete. Design of the sequential sealing machine is in progress. The test units sealed on the prototype sequential machine have completed processing and are comparable to the standard XLT device. No processing differences between Helium sealed and Nitrogen sealed units were observed. Three thousand hours of Matrix life testing was completed without failure or degradation of any unit. An economical study of Nitrogen sealed and Helium sealed units was completed, the results of which indicate that it not advantageous to use Nitrogen as the internal atmosphere for the unit. A new chuck has enabled the spiralling investigation to begin. Sixteen thousand pieces from four batches are in process. A lot of 531 type ceramics was shown to improve the process yield as film inspection about 5%. (Author)
