Activities aimed at improving work directors which program the instructions required for fabricating printed wiring board assemblies included designing solid-state switching circuitry for improved reliability, evaluating interface cabling techniques, studying visual-aid display-lamp mounting, and packaging innovations for product interface and troubleshooting convenience. The prototype solid-state work director functions satisfactorily. Recommendations for the design and fabrication of future work directors include wire-wrapped terminal construction technique and use of light-emitting diodes to replace conventional incandescent lamps.

This report covers the work done to analyze the optical output of a Light Emitting Diode. This diode consists' of a Monsanto MV2 LED chip in an MV50 package. A calculator based instrumentation system is described including programming techniques used to reduce and display data. A Light Instrumentation System with specially designed fiber optic cables is described which gathers data for processing by the calculator based instrumentation system. Future work will include analysis of the RCA 8571 Photomultiplier Tube.

A mechanical shock actuator has been converted into an air gun capable of firing 8-inch-·diameter (20.32 cm) projectiles to velocities exceeding 1000 fps (304.8 m/ s). This new capability has been used to study the effect of impact velocity upon the energy.absorbed by crushable materials. Shockpulse data is reduced by computer techniques and test results are displayed in either tabular or graphic format by use of the C DC 6600 Calcomp plotter.

Four specifications were written to describe requirements of microcircuit photomask generation and quality control. Processes developed were grouped under categories of layout and generation, inspection, serializing, and cleaning, handling, and storage.
