摘要:
A method for fixing an electronic component on a printed circuit board, and contact-connecting the electronic component to the printed circuit board, the following steps are provided:—providing the printed circuit board having a plurality of contact and connection pads,—providing the electronic component having a number of contact and connection locations corresponding to the plurality of contact and connection pads, with a mutual spacing reduced in comparison with the spacing of the contact and connection pads, and—arranging or forming at least one interlayer for routing the contact and connection locations of the electronic component between the contact and connection pads and the contact and connection locations of the electronic component. A method for producing an interlayer for routing and a system having a printed circuit board and an electronic component using the interlayer for routing are also provided.
摘要:
The invention relates to a method for removing a part of a substantially planar material layer (2) which is connected to at least one further, substantially planar material layer (9) in a connecting step. According to the invention, a zone where the material layers (2, 9) are not directly interconnected is provided in the zone where the part (11) is later on removed, said first zone being provided by applying a material (8) that prevents the material layers to be interconnected from sticking to each other. The invention also relates to a multilayer structure and to the use of the method and to a multilayer structure especially for producing a multilayer printed circuit board.
摘要:
In a method for producing a multilayer printed circuit board from a plurality of conducting or conductive and non-conducting or insulating layers or plies to be connected to each other, in particular to be pressed together, wherein after connecting at least partially planar layers at least a partial region (11) thereof is removed, and wherein in order to prevent adherence of the partial region (11) to be removed a material (8) preventing adhesion is applied in accordance with the partial region to be removed onto a layer (9) which adjoins the partial region to be removed, it is provided that the material (8) preventing adhesion is formed by a mixture comprising a release agent on the basis of at least one metal soap, preferably the fatty acid salts of Al, Mg, Ca, Na and Zn, a binding agent, and a solvent, whereby a partial region to be removed can be removed easily and reliably after appropriate treatment and/or processing steps of the multilayer printed circuit board. In addition, an adhesion prevention material and a use of the method in connection with the production of a multilayer printed circuit board (1) are provided.
