Abstract
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.
