<p>A manufacturing method of an embedded resistor flexible printed circuit board is provided to make a product size compact and increase the flexibility by reducing a whole layout area. A manufacturing method of an embedded resistor flexible printed circuit board is comprised of the steps: a base material layer is attached to the bottom of the base film in which a copper foil layer is laminated on the resistive layer;(S110) The dry film is adhered to on the base film to perform first exposure and a circuit pattern is formed by using the first etchant rusting the copper foil layer and the resistant layer(S120-S130).</p> |
