Abstract
A base for a printed circuit board is continuously produced by an apparatus comprising at least one degreasing vessel, at least one water pre-washing vessel, at least one electrodeposition coating vessel, at least one electrodepositing liquid-recovering vessel, at least one water post-washing vessel, and a transporting device for intermittently transporting the base successively through the above-mentioned vessels, which apparatus is provided with a device for conveying the base to a predetermined position above one of the above-mentioned vessels, stopping the base at that position, introducing the base into the vessel, keeping the base in the vessel for a predetermined time, and withdrawing the base from the vessel.
