Production Engineering Measure (PEM) manufacturing methods and technology for piezoelectric transformers

This is the final report on Contract DAAB07-76-C-0008, which established a cost-effective production capability for manufacturing piezoelectric ceramic transformers to be used in operating 18mm night vision image intensifier tubes. The 18 mm PET production approach established by this program produced acceptable units which met all of the specifications established for this high voltage step-up transformer. A one-element packaged PET was established in place of the original two-element developmental units. This was accomplished by establishing more realistic resistive and capacitive load requirements for each of the V12 and V3 voltage outputs. All of the equipment and tooling designed and built produced satisfactory pilot production run units. The cost objectives were achieved on the individual piezoelectric elements. Higher costs were associated with attaching leads to the PET ceramic elements and packaging was more time-consuming than desired.
