摘要:Printed circuit boards (6) with integral high and low value resistors (2 and 4) areefficiently produced. The method of their manufacture entails applying a first layer of alow resistance material (8) onto a dielectric substrate (6) in a predetermined thicknessand pattern. The pattern defines the electrical lengths and widths of low value resistors(2), as well as pairs of terminal electrode pads (28 and 30) for the high value resistors (4).A second layer of a high resistance material (18) is applied between and in contact withthe top surfaces of the facing ends of each member of the terminal pad pairs (28 and 30).The fixed lengths, widths and thicknesses of the patterned high resistance materialdetermine the values of the high value resistors. Conductive metal terminals are providedat the ends of the low value resistors and at the distal ends of the high value resistor padto complete the resistors.
