ZTACH® ACA Z-Axis Pressure-less Anisotropic Conductive Adhesive

ZTACH® ACA is applied as a paste without any pressure and then cured either with heat at low temperature (70˚C to 200˚C) or with UV in a magnetic field. The results in the self-assembly of conductive Z-Axis columns at regular intervals throughout the adhesive thickness. The columns create electrical and thermal interconnection in the Z-Axis, while maintaining electrical insulation in the X-Y plane. After formation, the columns maintain their structure due to immobilization within a now rigid polymer matrix.
