Abstract:
A process is disclosed for manufacturing printed circuit boards, printed circuit foils and semifinished products for printed circuit boards and printed circuit foils from blanks with electroconductive layers (7, 8) that may be structured into conductive patterns and substrates (4) that may be structured for forming connecting means (V), profiles (K) and conductive patterns (L). The connecting means (V), profiles (K) and conductive patterns (L) are structured at the same time or in the same process steps on the blanks. The connecting means (V) and the profiles (K) are part of the structured substrate (4) of the blanks. The electric or mechanical connecting means (V) are placed in a position in which they may be connected and the finished conductive patterns (L) may be detached around the profiles (K).
Abstract:
According to the invention, the power substrate is used as a base plate in a housing (1) which, together, form a standardized power part from whose top surface (11) connection pins (5) project. Said projection pins are soldered inside interfacial connection via holes of the control printed circuit board (4). The printed circuit board (4) comprises contact pads (7) which are located in an open strip area (6) and which serve as control terminals and power terminals by means of which the module can be soldered directly into the slotted opening of a system printed circuit board (8).
Abstract:
A magnetic component assembly includes a circuit board having at least one layer. A first winding is provided on at least one surface of a layer of the circuit board and a further winding is provided on the same or a different surface of the circuit board. A first magnetic core is associated with the first winding to define a first magnetic component and a further magnetic core is associated with the further winding to define a further magnetic component. There is thereby provided an assembly of two or more magnetic components integrated in a single circuit board providing an efficient space saving configuration. A particular application relates to the provision of integrated magnetic components for power supplies.
Abstract:
A printed circuit board (10) capable of resilient deformation having two major surfaces and a contact edge (18). Electrically conductive traces (14, 24) are provided on each major surface of the board which lead to electrically conductive contact pads (16, 26) at the contact edge of the board. A gap (22) is provided between the two major surfaces of the board along the contact edge. The gap permits resilient deformation of the board so that a force is created upon deformation which will bias the major surfaces toward their undeformed position. An elastomeric biasing member (28) may be provided in the gap.
