Abstract
The print wires 4 of an electroerosion printhead 1 are retained in grooves 3 of a substrate 2. These wires 4 are fixed to the substrate and covered by a copper layer 6. The copper layer is machined to provide a smooth surface on the copper and between the copper in the grooves and the surface of the substrate. Contact pads 7 are formed on or applied to the strip-like copper layers 6 to fan out the contact areas for suitable accessibility for attaching control cables 17.
