Abstract:
A circuit board (5) consisting of at least two individual circuit board layers (10) made of plastics and produced by formation technique, which each have first and second functional sides and at least one microstructured positioning formation (16), said at least one microstructured positioning formation being comprised of at least one projection and at least one recess positioned in interconnecting engagement, said at least one projection being formed on at least one of the first and second functional sides of one of said at least two individual circuit board layers (10), said at least one recess being formed on at least one of the first and second functional sides of another of said at least two individual circuit board layers (10) and positioned in interconnecting engagement with said at least one projection, each of said at least one projection and said at least one recess being formed integrally and simultaneously with one of said at least one individual circuit board layers during formation of said circuit board layers and being formed of material which is the same as the circuit board layer, and at least one microstructured conductor trench (12) on one of the functional sides, the conductor trench (12) being provided with a metallization (18).
