Abstract
A coating apparatus has one coating station with a downwardly directed device to coat both opposite surfaces of two sided circuit boards. One upwardly facing surface of a first board is coated at the coating station and moved to a handling station while a second board is moved to the coating station where its upwardly facing surface is coated while the first board is inverted at the handling station. The first board is then moved to the coating station while the second board is removed to a handling station, and the opposite side of the first board is coated at the coating station while the second board is inverted at the handling station. The two boards are exchanged in the coating station and then the opposite side of the second board is coated there while the first board is exchanged with a third board at the handling station. Two handling stations are preferred, equally spaced from the coating station, with two boards are simultaneously carried by a shuttle in two invertible pallets spaced on the shuttle a fixed distance equal to that of the coating station from the handling stations. Couplings at the ends of the shuttle engage pallet rotating drives as a pallet moves into the handling station.
