ABSTRACT:
Methods of manufacturing a variety of circuit protection devices are provided as well as devices so manufactured. In an embodiment, a surface mount electrical device having a substrate and a pair of conductive electrodes connected to an electrical protection component for sensing current or voltage is provided. The method includes the steps of: (i) providing a substrate having a first surface and a second surface; creating a first and second aperture, plasma etching a through-hole, slot or bore through the substrate; (ii) depositing a conductive material on the substrate and through the apertures to form the electrodes, wherein the conductive material extends through the apertures and on the first and second surfaces of the substrate, respectively; and (iii) depositing the electrical protection component on the first surface of the substrate to electrically connect the electrodes.
