<p>PURPOSE:To improve the reliability of a chip network resistor after mounting and, at the same time, to manufacture the resistor to have numerous networks by providing in advance groove type separators which decide the splitting direction of an alumina substrate to the substrate. CONSTITUTION:This chip network resistor is composed of a plurality of resistances and V-groove type separators formed into a substrate 1 between the resistances. These grooves do not affect the performance of this resistor. Because of the grooves, the direction of cracks and destruction of the substrate 1 are decided. Namely, since the thickness of the substrate 1 is extremely small at the parts of the separators 5, the substrate 1 cracks only at the parts of the separators 5 and does not crack at the parts of the resistances 4. Therefore, variation of the resistance value and occurrence of disconnection of the resistances 4 can be prevented.</p> |
