PRODUCTION ENGINEERING MEASURE FOR IMPROVEMENT OF GERMANIUM ALLOY POWER TRANSISTORS.

Abstract

Life test results are discussed for transistors on which surface passivation by oxidation was attempted. Results are discussed on surface passivation by organic coats according to the new procedure. Results are presented for Humidity Testing of pre-capped units. Results on the use of molecular sieve and calcium sulphate are discussed. Methods of improving soldering of the new clip are outlined. The program involving 10 mil collectors is presented. Program on the new tray, clip blower and hand tested is presented. The helium leak detector is now is operation on a 100% basis. Results on reliability measurements of transistors are presented. (Author)
