A method of manufacturing a fuse includes stacking a base plate, an at least partially conductive fabric over the base plate and a cover layer over the fabric, each with an intervening bonding layer. At least one cavity is provided on both sides of the fabric, adjoining the fabric, between the respective edge regions. In addition, the fabric includes at least one first fiber which is electrically conductive and second fibers which are non-conductive and which have a lower melting temperature than the first fiber. The method further includes heating the stacked elements to a temperature below the melting temperature of the first fiber and above the melting temperature of the second fibers.

A surface mount fuse has a housing, a conductive fuse and a cover. The housing has an opening and a non-airtight interior space. The conductive fuse is disposed inside the non-airtight interior space. The cover covers the opening. Because the interior space of the housing is a non-airtight interior space and the conductive fuse is disposed inside the non-airtight interior space. The conductive fuse is not encapsulated by the materials with low thermal conductivity to avoid heat accumulation, so the conductive fuse may avoid the aging. Further, the internal atmospheric pressure and the external atmospheric pressure of the housing may be balanced. Therefore, the conductive fuse is not suffered from the pressure caused by the pressure difference between internal and external of the housing so that the reliability of the surface mount fuse is enhanced.
