Abstract: Apparatus and process for continuously coating a web of current collectors with an electrically conductive adhesive material for electrochemical cells and batteries. The apparatus includes: (a) a source of the web of current collector material; (b) a reservoir containing the liquid composition; (c) a first rotatable roller having an exterior surface that is at least partially submerged in the liquid composition whereby liquid composition adheres to the exterior surface of the first rotatable roller which comes into contact with the liquid composition; and (d) a second rotatable roller that is positioned adjacent to the first rotatable roller and wherein an exterior surface of the second rotatable roller and an exterior surface of the first rotatable roller defines a nip through which the web of current collector material traverses.

Abstract: Epoxy application apparatus is provided to repetitively mechanically dispense the proper quantity and shape of epoxy on the substrate for the repetitive attachment of a small part such as a semiconductor die.Rotating epoxy pot has its surface refreshed, levelled and height controlled by a doctor or squeegee blade so that a transfer tool can pick up epoxy from the fresh surface behind the squeegee blade and place it on the substrate.
