Abstract
A continuous plating machine using a cooperating pair of endless tractor tread conveyor means to transport printed circuit boards through a plurality of process stations to complete stripping, cleaning, activation, plating and intermediate rinse cycles of the board terminals. The PC boards are captured between the opposing treads or shoes which serve as a masking means to protect the portions of the boards that don't require plating. The boards are electrically connected back through the conveyor means to the electrical current source.
