METHOD OF FABRICATING SURFACE MOUNT TYPE POLYMER FUSE FOR SHIELDING OVERCURRENT AND POLYMER FUSE THEREBY

摘要

PURPOSE: A method of fabricating a surface mount type polymer fuse for shielding over-current and a polymer fuse thereby are provided to connect electrically conductive layers to each other by using a conductive paste. CONSTITUTION: A PTC(Positive Temperature Coefficient) sheet is formed by depositing a first and a second conductive layer(20,30) on both sides of a conductive complex body. A plurality of through-holes are formed in a predetermined interval on the PTC sheet. A plurality of non-conductive gaps(50) are formed on the first and the second conductive layers. An insulating material(60) is coated on the non-conductive gaps. A conductive paste(70) is printed on an edge of the through-hole of the first conductive layer. The first conductive layer is electrically connected to the second conductive layer by inserting the conductive paste into the through-hole of the second conductive layer. A plurality of polymer fuses are formed by dividing the PTC sheet.
