I have not been able to locate information on the project you mentioned. Did the project publish an article? Do you remember the title? Three moves in as many years, I guess it is no wonder that people do not know we still exist. I think we have found a permanent home. We are working to cataloge the library. There is a lot of very valuable information here.

We found that as long as the Tce differential was < 5 ppm/C degree and the component was no larger that 0.5 inch we had long product life. Experiments were conducted with LCCCC in the early 80's time frame. - In addition, the Air Force funded some pretty comprehensive (MANTEC) studies that assessed the effect of Tce differential across five different substrates with various types of components. Contact the MANTEC office at WPAFB (if it still exists) for additional info on getting copies of MANTEC under FOI. - Hope the above helps.
