发明名称 Printed circuit substrate with resistance elements
摘要 In a printed circuit substrate incorporating a resistor pattern film and a conductor pattern film are formed on the two surfaces of a high conductive material layer such as a copper foil, respectively, in a predetermined positional relationship, and an insulating support is combined directly or indirectly with the resistor pattern film on the high conductive material layer, whereby a printed circuit board with resistance elements having high performance can be manufactured, while the number of processing steps can be greatly reduced.
