PRODUCTION ENGINEERING MEASURE TO IMPROVE PRODUCTION TECHNIQUES AND INCREASE THE RELIABILITY OF THE 2N328A TRANSISTOR.
Abstract
The PERT scheduling of the contract has been updated. All work is on schedule with appropriate account taken of the slack paths available. The etch wheel is 80% complete. Additional furnaces have been procured for the installation on onehalf of proposed new line after the installation of the etch wheel. The recirculator has been fully installed, evaluated, and made an operational part of the present alloy line. The recirculator produced a very significant increase in test box yield and an improved performance on step-stress testing. The oxygen analyzer has been installed but not fully evaluated. The can welding shield has been incorporated as part of the manufacturing line; preliminary evaluation by the Electromechanical stress tester of an improved form of C bend weld shield give indications of improvements to be expected here. Some success has been achieved in fabricating units by the aluminum evaporation technique, and preliminary evaluation of some of these units has been made. (Author)
