DuPont dielectrics are used for multi-layer and crossover structures, where high breakdown voltage, high insulation resistance, and good planarization properties are required.
DuPont dielectrics provide excellent insulation at reduced thickness with mechanical robustness to support soldered devices. Dielectrics deliver reliability in harsh environments and enable the use of inner-layer silver conductors to improve cost effectiveness, multi-layer circuits, and cross-over designs.
Many DuPont dielectrics for crossover and multi-layers can be fired using short firing cycles (below 30 minutes) without affecting their performance. Environmentally acceptable dielectrics (with PbO contents below 1%) are available to meet the stringent specifications on the use of the restricted materials.
