Claims19
A low resistance fuse comprising:
- a fuse element layer;
- first and second intermediate insulation layers extending on opposite sides of said fuse element layer and coupled thereto, said fuse element layer formed on said first intermediate insulation layer and said second insulation layer laminated to said fuse element layer, wherein said first intermediate insulation layer comprises first and second termination windows therein and;
- solder bump terminations located within said termination windows.
A low resistance fuse comprising:
- a thin foil fuse element layer comprising first and second contact pads and a fusible link extending between said first and second contact pads;
- first and second intermediate insulation layers extending on and in direct contact with opposite sides of said fuse element layer, at least one of said first and second intermediate insulation layers comprising a substantially cylindrical opening therethrough in the vicinity of said fusible link;
- a first outer insulating layer extending over said first intermediate insulation layer;
- a second outer insulating layer extending over said second intermediate insulation layer, at least one of said first and second outer insulating layer enclosing said opening of at least one of said first and second intermediate insulation layers;
- and
- solder bump terminations extending through said first outer insulating layer and said first intermediate insulation layer in electrical connection with said contact pads of said fuse element layer.
