Abstract
A network-type resistor array in which a plurality of resistors are successively arranged, in which electrode portions of the resistors are respectively separated by angular electrode-separating notches, so as to prevent the short-circuit between the adjacent electrode portions due to the flowing along of molten solder for electrode connection.
Claims4
A network-type resistor array comprising a resistory body, a plurality of resistors formed in adjacent relation in the resistor body, a plurality of electrodes mounted in spaced relation along a surface of the resistor body, and a plurality of multifaceted notches in the surface of the resistor body interposed between adjacent electrodes, each of the multifaceted notches having at least two substantially planar surface portions extending at an angle to each other.
A method for forming a network-type resistor array comprising forming a resistor body using a first die having multifaceted shaft pins and a second die having multifaceted recesses corresponding to the shape of the multifaceted shaft pins, and forming one surface of the resistor body with the shaft pins so that the surface has spaced electrode regions separated by multifaceted notches having at least two adjacent, substantially planar surface portions extending at an angle to each other.
