Abstract: The present invention provides overvoltage circuit protection. Specifically, the present invention provides a voltage variable material (“VVM”) that includes an insulative binder that is formulated to intrinsically adhere to conductive and nonconductive surfaces. The binder and thus the VVM is self-curable and may be applied to an application in the form of an ink, which dries in a final form for use. The binder eliminates the need to place the VVM in a separate device or for 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 or a polymer. The VVM can also be directly applied to different types of substrates that are placed inside a device.

Vias may be formed to the bottom plate by using a disjoint structure and conductive paste technology. Connection to the passive components may be made by conductive paste-filled channels forming conductive patterns on the substrate.

The improved assembly provides increased isolation of incoming electrical wires with less material than previous devices.
