Q-Prime: A proprietary circuit technology with thermally conductive adhesive and a thin composite structure.
Bus Bond® a family of insulation materials used as inner and outer layers in the production of laminated busbars is introduced to the market.
Roll-to-Roll “PEDOT” (Poly(3,4-ethylenedioxythiophene)) screening printing offered to the marketplace.
Sheldahl high volume roll-to-roll ITO patterning and screen printing capability is established
Sheldahl is purchased by Multek
Sheldahl provided the world’s first roll-to-roll of patterned ITO material for the display market.
Sheldahl introduced a family of ITO films to the market under the trademark: ACCENTIA®
Sheldahl introduced ComClad™ HF a family of high-frequency laminates designed for use in the wireless communications market.
ViaGrid® was developed. A Novaclad® based microcircuit substrate with a pattern of either uniform or custom placed conductive holes.
Novalink® a multilayer circuit constructed with Novaclad® or Novaflex® and Z-Link® adhesive was introduced to the market.
Novaclad® a copper on film flexible material was introduced. The Novaclad® was produced by vapor depositing copper directly onto the surface of a polyimide film and then additional copper is plated to the desired thickness.
Sheldahl introduced Z-Link® an inter-connective circuitry system based on an adhesive that conducts electricity only in the Z (vertical) axis.
