<p>A method of cloning printed wiring boards using a reverse engineering technique. Many printed wiring boards are no longer manufactured because the manufacturer is no longer in business or the boards have become obsolete. A need exists to duplicate printed wiring boards which are no longer manufactured. Accordingly, a new method of cloning printed wiring boards includes the steps of removing (10) all components from the printed wiring boards, drilling and routing (12) component interconnection points on the printed wiring boards, milling (14) the opposite sides of the printed wiring boards to a minimum thickness, X-raying (16) the board to produce a film negative, photographing (18) the negative to provide a reversed negative and converting the reserved negative film to a diazo photograph.</p> |
