Presentation Summary

  • Direct Write (DW) Technologies have potential to alter how electronics are used in aerospace by distributed electronics, replacing conventional components, and putting electronics in places not previously possible.
  • Aerospace environments are extreme and any component needs to be able to function under all conditions.
  • Extensive testing of DW components is needed not only for electrical performance, but mechanical survivability as well.
  • A discussion of what we see as some potential DW applications and the required testing needed to use these technologies in aerospace will be discussed.
