Abstract:
The invention relates to a method for welding a conductor to a conductive film, which is preferably connected to a circuit board support in order to produce a printed circuit board, the depth or diameter of the conductor being preferably larger than the thickness of the conductive film. According to said method, the conductive film is in contact with a thermal isolation plate, at least during the welding process, the thermal conductivity of said plate being lower than that of the conductive film.
Abstract:
The invention relates to a wire-printed circuit board or card (1) comprising conductors (6) that run on and/or in the circuit board or card between connection points (4). The aim of the invention is to improve a circuit board of this type. To achieve this, at least one of the conductors (6) has a rectangular or square cross-section. In addition, at least some of the conductors have a hollow cross-section, in which a coolant or heating agent circulates.
Abstract:
The invention relates to a method for producing an angled printed circuit board structure from at least two circuit board sections, said method comprising the following steps: a) production of a level printed circuit board (1) comprising at least one conductor (4), which is embedded to a great extent in the printed circuit board (1), extends between two regions of the printed circuit board (1) that are configured as connection points (6) and is connected to the latter in an electrically conductive manner, the two regions that are configured as connection points (6) being located on different printed circuit board sections (12, 14, 16, 18, 20, 22); b) provision of at least one region that is designed to be angled, preferably an edge (28) between the printed circuit board sections (12, 14, 16, 18, 20, 22). Said circuit board sections (12, 14, 16, 18, 20, 22) can be angled in relation to one another, whilst retaining the conductor connection between the regions that are configured as connection points (6) by bending said conductor(s) (4).
Abstract:
A method provides for welding a conductor to a conductive film which is suited for connection to a circuit board support in order to produce a printed circuit board. The depth or diameter of the conductor is preferably greater than the thickness of the conductive film. At least during the welding process, the conductive film is maintained in contact with a thermal isolation plate having a thermal conductivity less than that of the conductive film. After being placed on the circuit board support, the conductive film is partly etched away to electrically isolate electrical contact points.
