Abstract
A method for producing a circuit board involves printing a U.V. curable ink onto a substrate in a desired circuit pattern and curing the ink by exposing it to a pulsed U.V. source or subjecting the circuit pattern prepared from a U.V. curable ink containing magnetite particles to a magnetic field to move the magnetite particles to the upper surface of the U.V. curable ink. Other embodiments include circuit boards made in accordance with these methods and the use of the U.V. curable ink as a shielding composition for enclosures housing electronic equipment.
