摘要： A solution is disclosed for swelling printed circuit polymers before the boards are subjected to an alkaline-oxidative etching step and their bores are cleaned. An organic solvent is added to an aqueous solution for swelling printed circuit board polymers before the boards are subjected to an alkaline-oxidative etching step. As organic solvent, a straight-chain carbonic acid ester having the general formula R1-O-CO-O-R2, in which R1 and R2 represent C2- to C4-alkyl, or a cyclic carbonic acid ester, such as propylene or ethylene carbonate, are added to the solution. This swelling solution allows the boards to be processed at lower temperatures, avoids the formation of pocket-voids and reduces losses by evaporation. The invention is useful for cleaning bores of printed circuit boards in electrical engineering and electronics.

摘要： A device for screening off lines of electric flux in an installation for electrolytically processing essentially flat elements (8) composed of one or several pieces held underneath a support (4) and submerged in a bath when the support is lowered has a screen (10) that can be vertically adjusted by holders (5) coupled to the movement of the support. In order to avoid the inconvenients of state-of-the-art guides of the screen in the plating tank without losing the advantages obtained thanks to the holders, with a simple, compact structure, downwardly projecting rods (5) that bear on both ends (10') of the screen (10) are used as holders for the support. The lower ends of the rods (5) and the ends (10') of the screen (10) are so designed that the screen cannot move with respect to the rods, at least in its longitudinal direction, and that the distance between the rods (5) is larger than the width of the elements (8) located during processing between the rods. Means for transporting the screen from its lower working position to a top parking position are provided. The elements to be processed hang from their support (4) without lateral guides and no guides are provided between the plating tank (1) and the screen (10).

摘要： The invention relates to an arrangement for an installation used for the electrolytic treatment of workpieces comprising two anode bars (2) with series-mounted anodes (A) and one cathode bar (3) with series-mounted workpieces (W). In order to ensure in a simple manner and without major power losses that the individual workpieces are each subjected to the same cell voltage, thereby producing the desired material deposit of approximately the same thickness of each workpiece, different cross sectional ratios of the anode bars (2) to the cathode bar (3) and/or changes in the electrical resistance of these bars per unit of length and/or resistors (R) between the individual anod bars (2) and the respective associated anode (A) are used in order to supply defined current levels to the anode bars (2) and give a defined current output from the cathode bar (3).

摘要： Disclosed is a process for throughplating bores in plate-like workpieces, in particular circuit boards, and a device for carrying out the process. The aim of the invention is to make it possible to carry out bore throughplating in a continuously operating installation. The invention calls for a fluid to be fed concentrically to a driven roller with valves which open apertures only during contact with the circuit board. A second roller holds the circuit board against the first roller. This device enables roller-gap losses to be minimized, thus giving controlled throughplating and hence reducing considerably the required pump rating.

摘要： The invention is based on a process for ion exchange in aqueous solutions by means of ion exchange resins (hereinafter abbreviated to 'resins') in ion exchangers in which the resins are alternately charged, regenerated, and possibly treated and rinsed. In order to be able to remove the solution concerned without problems and also more economically, the process first provides for containers (18) with the resin (19) to be taken into a treatment chamber (17) whereafter the aqueous solution is introduced into the container and directed through the resin. Then, by lifting the container and holding it above the treatment chamber, the solution in the container and resin is caused to run off. Thereupon the container is taken to one or more chamber(s) (34, 36, 37, 37') of a regenerating, treating or rinsing station into which it is lowered and treated with the regenerating solution. Then, once again, by lifting the container and holding it above the regeneration chamber, the remaining regenerating solution is caused to run out of the container and the resin. Finally the container is taken to a further chamber for charging or regeneration. The invention also concerns an installation for implementing the process.
摘要翻译：本发明是基于离子交换树脂交替填充，再生和可能的处理和漂洗的离子交换树脂在离子交换树脂（以下简写为“树脂”）中在水溶液中进行离子交换的方法。为了能够在没有问题的情况下更经济地去除有关的解决方案，该方法首先提供容器（18），使树脂（19）进入处理室（17），之后将水溶液引入容器并引导通过树脂。然后，通过提起容器并将其保持在处理室的上方，导致容器和树脂中的溶液流出。于是容器被带到再生，处理或漂洗站的一个或多个室（34,36,37,37'），再次下水处理或冲洗站用再生溶液处理。然后，再次通过提起容器并将其保持在再生室上方，使剩余的再生溶液从容器和树脂中流出。最后，将容器带到另一个室进行充电或再生。本发明还涉及用于实现该过程的安装。

摘要： A process is useful for controlling the flow of operations in electroplating plants with horizontal throughflow in which the parts to be electroplated, in particular plate-shaped parts, pass through the plant in succession and are electroplated by means of currents applied by anodes. In order to prevent undesirable, increased precipitation on the front faces or edges of parts to be electroplated which follow each other at undesirable distances apart, or at least to reduce this precipitation to an acceptable level, the position of the parts (1) which pass through the plant in succession and/or the distances (a1, a2) between these parts are detected and the application of the electroplating currents is controlled in function of these positions and/or distances by switching the anodes (4, 7) on and off, in such a manner that the flux density is approximately the same in all regions of the parts (1). The invention also concerns an arrangement for implementing the process.
