Abstract
A method for manufacturing a miniature resistor includes the steps of: providing a foil sheet; forming intersecting rows of slits to define a patterned foil sheet having a matrix array of resistor blanks that are interconnected at intersections of the intersecting rows; forming a resin film on a bottom surface of the patterned foil sheet; forming a plurality of protruding blocks on each resistor blanks; forming an encapsulating layer on atop surface of each resistor blanks without covering outer surfaces of the protruding blocks; performing a die cutting process to obtain individual resistor blanks; and forming two external electrodes respectively on the protruding blocks and on two side surfaces of the individual resistor blanks to obtain the miniature resistor.
