Tool for manufacturing a circuit pattern of an electrical circuit board by cutting of a copper plate and the circuit pattern of an electric circuit board which is suitable for work with the tool

摘要

The invention relates to a tool for manufacturing a circuit pattern of an electrical circuit board with conductor and earth tracks and connecting points for components, by cutting a copper plate with the aid of dies (1) and pressing pads (3) associated with the dies, along the edges of the tracks and connecting points. In this case, tool parts arranged on both sides of the copper plate (8) consist entirely of individual dies (1a) and moving individual pressing pads (3a) with mutually connecting die and pressing pad surfaces (1b, 3b) of a common rectangular cross-section, which are arranged side by side in the manner of a matrix grid. Program boards (4, 6) are provided on the die and pressing pad ends which are remote from the copper plate (8). The program boards have a relief of the circuit pattern (5, 7) constructed as a mirror image, for the dies (1) and pressing pads (3). When the program boards (4, 6) are pressed together between the mutually moving dies (1a) and pressing pads (3a), the copper plate (8) is cut in accordance with the relief (5, 7). IMAGE
