Abstract
DE 19736352 C UPAB: 19990122 The apparatus is for electrical wet contacting of flat items (7) in galvanizing installations, with use of soluble or insoluble anodes (2) and clamps (4) attached to an endless circulating transport unit. The clamps consist of electrically conductive bare metal top and bottom members (13, 14) which are movable relative to one another, and have a contact point below the bath surface (8). The apparatus is provided with shields (15, 16) between the anodes and the clamps. USE - In manufacture of circuit boards and foil, for example. ADVANTAGE - The apparatus can be produced cost-effectively. It can be operated for long periods without maintenance. The same coating thickness distribution is attained on the entire surface of the items undergoing galvanizing.
