Abstract

A device for releasably-holding printed circuit boards to be galvanized in a galvanization bath comprises an elongated frame, and arrangements for holding opposite longitudinal edges of the boards on the frame. The holding arrangements are electrically conductive. The frame includes two spaced paralled subframes. Each holding arrangement includes resilient clamping springs arranged on the subframes and freely extended outwardly from each subframe and also extending into a space between the subframes to enable an insertion into and a withdrawal from the clamping springs of respective elongated edges of each printed circuit board.
