Patent ID: 7123125

Claim:
A method of manufacturing a surface mounted resettable over-current protection device, comprising the steps of: providing a raw material substrate having two ends, on each of the two ends of which a patterned conducting metal foil is arranged; cutting the raw material substrate to form a grid-shaped substrate having a plurality of strip-shaped structural parts; forming an insulating layer, the insulating layer enclosing the grid-shaped substrate, and allowing parts of the patterned metal foils adjacent to the both ends of the strip-shaped structural parts to be exposed; cutting the strip-shaped structural parts of the grid-shaped substrate into a plurality of chips, each of the chips having two cut sections; and forming two terminal electrodes on the two cut sections, respectively, the two terminal electrodes enclosing the insulating layer and the two cut sections exposing parts of the patterned conducting metal foils, the two terminal electrodes electrically connected to the two cut sections which exposes the parts of the patterned conducting metal foils.
