A voltage variable material ("VVM") including an insulative binder that is
formulated to intrinsically adhere to conductive and non-conductive
surfaces is provided. The binder and thus the VVM is self-curable and
applicable in a spreadable form that dries before use. The binder
eliminates the need to place the VVM in a separate device or to provide
separate printed circuit board pads on which to electrically connect the
VVM. The binder and thus the VVM can be directly applied to many
different types of substrates, such as a rigid FR-4 laminate, a
polyimide, a polymer or a multilayer PCB via a process such as screen or
stencil printing. In one embodiment, the VVM includes two types of
conductive particles, one with a core and one without a core. The VVM can
also have core-shell type semiconductive particles.
