Abstract:
1. A method for making a surface-mountable electrical circuit protection device comprising steps of: (a) forming a substantially planar polymeric positive temperature coefficient resistive (“PPTC”) layer having predetermined electrical characteristics and physical dimensions including first and second major surfaces, forming a first electrode layer at the first major surface in intimate electrical contact therewith, and forming a second electrode layer at the second major surface in intimate electrical contact therewith; (b) forming first, second and third terminal electrodes along at least one major edge wall of the device, the first terminal electrode being in electrical connection with the first electrode layer, the second terminal electrode being in electrical connection with the second electrode layer, and the third terminal electrode being electrically isolated from the first and second terminal electrodes; (c) bonding a first metallized face of at least one heat-generating electrical element to a part of the first electrode layer arranged to receive the heat-generating electrical element; and, (d) connecting a second metallized face of the at least one heat-generating electrical element to the third terminal electrode with an interconnect structure.
