Problems solved by technology

[0004] Since such treatment solutions lose their treatment properties when used for a longer period of time, they must be regularly replenished, or completely or partially replaced, which in turn is expensive

Embodiment Construction

[0055] The same reference numerals are used for identical or identically acting elements of the invention. The illustrated embodiments present only examples of how the devices and methods of the invention may look like, and do not represent any definitive limitations.

[0056] figure 1 The schematic diagram of FIG. 1 shows an embodiment of the device 10 according to the invention for the at least partial regeneration of the treatment solution 12 comprising permanganate in the treatment tank 14 . The processing tank 14 is used to process (eg, etch) the plastic substrate. The device 10 will reduce the concentration of carbonate compounds in the treatment solution 12 . The device 10 comprises as basic elements a cooling tank 16 and a downstream filtering device 20 . The treatment solution 12 to be regenerated is passed from the treatment tank 14 to the cooling tank 16 , wherein the cooling device 18 is dedicated to the cooling tank 16 . The cooling device 18 sends cold to the...

Abstract

The present invention relates to a method for treating of plastic parts with a treatment solution comprising permanganate wherein the concentration of carbonate compounds in the treatment solution is set to a value less than 200 g / l by the removal of carbonate compounds from the treatment solution by freezing out and subsequent filtration wherein the treatment solution comprises sodium permanganate. The invention further relates to a device for an at least partial regeneration of a treatment solution comprising permanganate, which is used for treatment and / or etching of plastic parts by reducing of a concentration of carbonate compounds comprised in the treatment solution for the implementation of such a method, wherein the device comprises at least one cooling tank which is to be subjected to the treatment solution to be regenerated, and which exhibits a downstream filter device for separating the carbonate compounds from the treatment solution; and additionally the use of such a device for implementing such a method.

Description

technical field [0001] The invention relates to a method for treating (in particular etching) plastic substrates, especially printed circuit boards and printed circuit foils, with a treatment solution comprising permanganate, having the features of the independent method claim 1 . The invention also relates to a device for at least partial regeneration of a treatment solution comprising permanganate for the treatment of plastic parts, in particular printed circuit boards and printed circuit foils, having the features of independent device claim 8 and / or etch. Background technique [0002] Treatment or etching of plastic substrates (e.g. plastic molded parts or especially printed circuit boards or printed circuit foils) with a solution comprising permanganate is usually carried out as a preparatory step for metallization of the surface or openings of the substrate . Thus, the substrate is brought into contact with a suitable treatment solution in a treatment tank of an impr...
