  • Printed circuit fabrication
    Patent number: 6858352
    Abstract: A mask for producing a printed circuit board is defined in which the conductor elements of the printed circuit pattern are delineated by a constant width etch band (20). This means that all conductors (3a, 3b, 9) are separated from neighboring areas of conductive material (22) by the same distance. Thus etch rates across the printed circuit pattern do not vary according to the separation of the conductors (3a, 3b, 9).
