A method for embedding a component in a printed circuit board or a printed circuit board intermediate product, wherein the printed circuit board or the printed circuit board intermediate product comprises at least one insulating layer made of a prepreg material, and the component is fixed by the resin of the prepreg material, is characterized by the following steps:

Method for embedding a component in a printed circuit board

A method of manufacturing a component carrier includes providing a base structure having a main surface that is at least partially covered by a component fixation structure; providing a component, the component intrinsically comprising warpage; mounting the component on a surface provided on a plate structure and/or on the base structure to remove the warpage of the component at least partially; and fixating the component to the component carrier through the component fixation structure.

Embedding component in component carrier by component fixation structure

A manufacturing method, wherein the method includes providing a layer stack having at least partially uncured component carrier material, arranging a plurality of components in recesses of the layer stack, integrally connecting the components with the layer stack by curing the component carrier material, and applying a high temperature robust dielectric structure on a main surface of the cured layer stack with the components therein.

Method of embedding a component in a printed circuit board

A method of manufacturing a circuit board or a circuit board intermediate product, wherein the method comprises providing a carrier structure, applying a layer of flowable low-viscosity adhesive on the carrier structure over a surface area of the carrier structure which is larger than a mounting area in which an electronic component is to be mounted on the carrier structure, and pressing the electronic component into a subsection of the layer of adhesive in the mounting area so that at least part of the electronic component is immersed within the adhesive.

Placement of component in circuit board intermediate product by flowable adhesive layer on carrier substrate

A circuit board and a method of manufacturing a circuit board or two circuit boards are illustrated and described. The circuit board includes (a) a dielectric layer with a planar extension in parallel with respect to an xy-plane which is spanned by an x-axis and a y-axis perpendicular thereto and a layer thickness along a z-direction which is perpendicular with respect to the x-axis and to the y-axis; (b) a metallic layer which is attached to the dielectric layer in a planar manner; and (c) a component which is embedded in the dielectric layer and/or in a dielectric core-layer of the circuit board. The dielectric layer includes a dielectric material which has (i) an elastic modulus E in a range between 1 and 20 GPa and (ii) a coefficient of thermal expansion in a range between 0 and 17 ppm/K along the x-axis and along the y-axis.

A circuit board is described which includes a layer composite with at least one dielectric layer which includes a planar extension in parallel with respect to an xy-plane which is spanned by an x-axis and a y-axis perpendicular thereto, and which includes a layer thickness along a z-axis which is perpendicular with respect to the x-axis and to the y-axis; and at least one metallic layer which is attached to the dielectric layer in a planar manner. The layer composite along the z-axis is free from a symmetry plane which is oriented in parallel with respect to the xy-plane, and the dielectric layer includes a dielectric material which has an elastic modulus E in a range between 1 and 20 GPa and along the x-axis and along the y-axis a coefficient of thermal expansion in a range between 0 and 17 ppm/K.
