Abstract
A method for manufacturing a circuit board with nickel resistor embedded therein provides a copper substrate, the copper substrate includes a copper foil. A nickel resistance layer is formed on the copper foil. A first dielectric layer and a first copper layer are formed on the nickel resistance layer. The copper foil and the first copper layer are etched to form a first conductive wiring layer and a second conductive wiring layer respectively, the nickel layer not being subjected to an etching process, to obtain the finished circuit board.
