摘要:
The invention pertains to a method for the bonding of a component embedded into a printed circuit board exhibiting the following steps: Provision of a core exhibiting at least one insulating layer and at least one conductor layer applied to the insulating layer, Embedding of at least one component into a recess of the insulating layer, wherein the contacts of the component are essentially situated in the plane of an outer surface of the core exhibiting the at least one conductor layer, Application of a photoimageable resist onto the one outer surface of the core on which the component is arranged, while filling the spaces between the contacts of the component, Clearing of end faces of the contacts and of the areas of the conductor layer covered by the photoimageable resist by exposing and developing the photoimageable resist, by application of a semi-additive process, deposition of a layer of conductor material onto the cleared end faces of the contacts and the cleared areas of the conductor layer and formation of a conductor pattern on at least the one outer surface of the core on which the component is arranged, as well as the interconnecting paths between the contacts and the conductor pattern, and Removal of the areas of the conductor layer not belonging to the conductor pattern.
