Selection and evaluation of organic dielectric materials for spacecraft

A major factor in the successful completion of missions such as Surveyor I and the various communication satellites has been the extreme care taken in the choice of the insulating materials for the electronic units on these spacecraft. Extensive evaluations and close quality control of these materials resulted in assuring a superior reliability of all the electronic devices. The need for lightweight, high density electronic packaging designs has demanded the use of a number of materials, composites, and unique processing steps not normally considered for conventional airborne and missile applications.
