ACI Materials

ACI FE3124 is a silver filled flexible conductive trace ink for use on PET, polyimides, and other bendable substrates. It offers high conductivity (< 0.010 Ω/sq/mil) and low slump for feature resolution less than 100 μm. After cure FE3124 has excellent adhesion and flex ductility to accommodate various packaging form-factors and use cases. The ink is fully compatible with other products in ACI’s flexible electronics platform.

FE1334 is compatible with flexible and stretchable systems where high electrical conductivity is required. This stretchable conductive adhesive accommodates bending and stretching along the bond line and improves interconnect robustness and reliability. FE1334 can be deposited via stencil, syringe, or jet dispensing and cures with low shrinkage. The combination of high electrical conductivity (<9e-5 Ω-cm), high shear strength (>1,500 kPa), and high adhesion to a broad range of materials makes it a good choice for bonding in many flexible and stretchable applications. It is also appropriate for bonding rigid components in packages with large thermally induced strains.

ACI SE1108 is a silver filled conductor for printed circuitry and devices on elastomeric substrates. It can be dried at low temperatures to accommodate sensitive substrates and devices. After curing, the ink has excellent conductivity and offers excellent elongation and flexibility. SE1108 has been formulated for superior adhesion to thermoplastic urethanes (TPU). It is compatible with ACI’s other stretchable materials.
