Method for controlling the work cycle of electroplating plants

The apparatus for treating and/or cleaning an object, especially a circuit board, with a flood flow of fluid comprises means for moving the object along a path in the apparatus and a number of flood flow devices past which the object is moved on the path, all of which are located above the path. A fluid damming means, preferably a pressing roll contacting the path, may be provided on each of the long sides (the sides transverse to the feed direction) of each flood flow device so that in operation a fluid pool arises around each flood flow device. The flood flow device advantageously comprises a plurality of fluid feed pipes, a fluid receiving chamber of a larger diameter than the feed pipes receiving fluid from them, a perforated mask located downstream in the fluid receiving chamber provided with a plurality of through-going holes and a distributor chamber provided with an outlet mouth located downstream of the perforated mask, the distributor chamber with the outlet mouth and the path defining a flooded space above the path. The fluid receiving chamber, the distributor chamber, the outlet mouth and the flooded space extend substantially over the entire length L of the flood flow device.

The continuous process for making a metal structured foil, especially a flat conductor line, a flexible circuit board and a heating foil, by chemically and electrochemically metallizing a nonconductor foil, comprises the steps of:

Process and apparatus for making a metal structured foil

Cleaning, activating and metallizing of bore holes in conductor boards is performed by supplying a liquid treatment medium in form a standing wave onto a lower side of the conductor board by a surge line which is formed as a nozzle arranged under a transporting path and substantially normal to a transporting direction of the horizontally guided conductor board.

Method of and arrangement for cleaning, activating and metallizing of

A device for guiding plate-shaped objects to be electro-plated through an electro-plating bath in a container, includes a device transporting said objects to the container in a horizontal position, a device for pivoting the objects in the bath from a horizontal position about a horizontal axis so that the objects assume a position below the mirror of the bath. The pivoting device guides the objects through the container and, at the outlet thereof, pivots the objects back to the horizontal position.

Method of and device for guiding plate-shaped objects

A device for electroplating electric circuit boards includes an electroplating bath and a plurality of transporting organs which hold objects to be treated when they path the electroplating bath. The transporting organs are pairs of clamping yokes arranged on a common endless rotating belt and positionable from a clamping position in which they engage the object being treated and a release position in which they release said object.

Device for the electroplating treatment of plate-shaped objects

A device and method for the treatment of printed circuit boards with process solutions, in which the boards being treated are continually vertically moved by a transporting conveyer above an accumulating reservoir and below spraying nozzles which apply a process solution to the side surfaces of each board. Two collecting receivers are arranged in mirror-inverted relationship at two sides of the boards being treated. The reservoir, into which the process solution drains from the receivers and the boards, is connected to the spraying nozzles by tubular conduits, provided with regulating valves, in a closed circuit, whereby the accumulated solution is fed back to the nozzles.

Method and device for the treatment of printed circuit boards

An arrangement is disclosed for the galvanic deposition of metal at relatively greater speed and with controllable layer-thickness distribution, of the type composed of an electrolysis tank with overflow, electrodes, nozzles, connecting conduit tubes, pumps, control system means and dosaging system means as well as electrical appurtenances, wherein a cathodically-connected work piece to be galvanized is arranged between two nozzles which are each formed from two chambers located one above the other and having separate entrance and exitways, the upper chamber contains an electrolyte exit opening provided as a longitudinal slit and the lower chamber defines an anode niche displaying at the height of the slit a vertically-adjustable opening. Also disclosed is a method for the electrolytical deposition of metal, employing substantially the above described arrangement and particularly for depositing nickel- or gold-coatings on plug contacts of printed circuits.

Apparatus for the galvanic deposition of metal

Cleaning of objects from adhering liquid surface treating medium after galvanic and/or chemical surface treatment and recovery of the liquid medium is performed by lifting objects treated in a working container by a drum aggregate, bringing two half shells over the drum aggregate to embrace the latter so that at only a lower region of the drum aggregate a gap remains, and blowing a gas stream through the half shells to the drum aggregate so that an adhered treating medium is removed from the objects and flows directly back to the working container through the gap.

System for removing adhering liquid from objects after a galvanic or

An apparatus for chemically and electrochemically processing, especially electroplating, flowable bulk material comprises a tank containing a chemical solution and a device forming a trough receiving the material to be processed, the device is removably supported on the tank to extend into the solution. The trough forming device comprises a perforated belt, preferably of plastic material and trained over an upper and a lower reversing roller and a tension roller turnably mounted on a pair of transversely spaced side plates, which laterally define the trough in such a manner that the upper run of the belt has a first branch extending from the lower reversing roller to the deepest point of the trough at a small angle to the horizontal, whereas the second branch of the upper run which extends from the deepest point to the upper reversing roller extends nearly in vertical direction. The belt is driven over a gear transmission by a reversible electromotor. During processing of the material the belt is driven in a direction so that the upper run moves from the lower reversing roller to the upper roller, whereby the steep branch prevents removal of the material from the trough, and after the processing of the material is finished, the trough forming device is lifted out of the tank and the drive of the belt is reversed so that the material will be discharged from the device over the first branch of the upper run and the lower reversing roller.
