Problems solved by technology

This in turn causes the laser beam to damage the substrate in areas with less layer thickness
Another disadvantage of this known method is that even very small areas are plated, many varnishes are required in order to completely coat the substrate with one coat of varnish
Extreme build-up of paint becomes more difficult especially in the case of thicker paint layers and especially in the case of three-dimensional substrates required to obtain a complete paint layer
Also consider that the paint materials required for this method are more expensive

Embodiment Construction

[0031] figure 1 The illustrated electroplating plant for partial plating of base strips is designed as a so-called reel-to-roll plant, in which the metal base strip 10 is continuously unwound from a first drum or reel 11 and passes through the electroplating plant again as a finished processed strip The material is rolled onto a second drum or reel 12. In this case, belt speeds of 20 m / min or higher are feasible.

[0032] First, the base tape 10 passes through a preparation station 13 where the base tape 10 is cleaned, activated and rinsed.

[0033] Next, the base strip 10 passes through a painting station 14, where partial electrophoretic painting is carried out. The painting station 14 may include one or more painting units 15, such as figure 2 as indicated. Such a painting unit generally comprises an encapsulating housing which is protected against uncontrolled deposition of paint in unintended areas. For this purpose, the webs 17 , 18 , which are made of Teflon or an...

Abstract

A method for the continuous selective electroplating of a metallic substrate material ( 10 ) and more particularly of a substrate material band having prestamped contact elements, comprises the following steps: a) the substrate material ( 10 ) is coated in an electrophoretic coating means ( 14 ) with an electrophoretic coating composition selective with at least one composition strip, b) the at least one composition strip is removed at those parts by means of a laser ( 40 ), which are to be electroplated, c) in an electroplating process a metal layer is applied to the areas ( 42 ) deprived of composition in at least one composition strip using selective electroplating and d) the at least one composition strip is then removed.

Description

technical field [0001] The invention relates to a method for the continuous partial electroplating of strip-shaped metal substrates, in particular substrate strips with pre-punched contacts. Background technique [0002] In the method as disclosed in DE 19934584 A1, the substrate is first completely coated with paint by spraying or dipping in the paint. The lacquer is then removed by means of a laser at those points where the contact material is to be applied. [0003] In this known method, only paint layers of uneven thickness can be disadvantageously obtained by either spraying or dipping. This problem becomes acute for three-dimensional substrates, since the paint then builds up very thickly in the corners. Furthermore, the complete paint layer which is absolutely necessary for this method can only be obtained with relatively thick paint layers. When lasers are used to remove material from the areas to be plated, this results in long working hours or high power lasers ...
