  • Patent number: 10051747
    Abstract: Methods for the production of a circuit board involving the removal of a subregion in accordance with various embodiments of the invention are disclosed. In one embodiment, the production of a circuit board, made of at least two interconnected layers of material, involving the removal of a subregion including a portion of at least one of the at least two interconnected layers from the circuit board includes providing an adhesion preventing material under the subregion to be removed to a layer in the at least two interconnected layers that is adjacent to the at least one layer including the subregion, separating edge regions of the subregion to be removed from adjoining regions of the circuit board, connecting an external surface of the subregion to be removed to an external element, and displacing the external element to separate the subregion to be removed from the adjacent layer of the circuit board.

  • Patent number: 9980380
    Abstract: In a method for producing a printed circuit board consisting of at least two printed circuit regions, wherein the printed circuit board regions each compromise at least one conductive layer and/or at least one device or once conductive component, wherein printed circuit board regions to be connected to another one, in the region of in each case at least one lateral surface directly adjoining one another, are connected to one another by a coupling or connection, and wherein, after a coupling or connection of printed circuit board regions, at least one additional layer or ply of the printed circuit board is applied over the printed circuit board regions, the additional layer is embodied as a conductive layer, which is contact-connected via plated-through holes to conductive layers or devices or components integrated in the printed circuit board regions.

  • Patent number: 9374906
    Abstract: In a method for pre-treating a frame or carrier element for use in the production of a printed circuit board, wherein after the pre-treatment the frame or carrier element is coupled with at least one circuit board element and subjected to at least one processing or treatment step, particularly at an elevated temperature, together with the circuit board element, in particular mounting or populating of the circuit board element, it is provided that the frame or support or carrier element is subjected to a heat treatment at temperatures between 120° C. and 350° C., in particular 200° C. to 300° C., for a time period (ttot) of 5 to 300 seconds, in particular 10 to 200 seconds, whereby frame or carrier elements can be provided, which are reliably stable in terms of shape and dimensions.

  • Publication number: 20140331494
    Abstract: The invention relates to a method for producing a circuit board (1) involving the removal of a subregion (6) thereof. In said method, at least two layers or plies (2, 3, 4, 5) of the circuit board (1) are interconnected, the subregion (6) to be removed is prevented from being connected to an adjacent ply (4) of the circuit board (1) by providing or applying an adhesion-preventing material (7), and peripheral zones (8) of the subregion (6) to be removed are separated from adjoining zones of the circuit board (1).
