Embodiment approach

[0064]According to an exemplary embodiment of the present invention, a dielectric low modulus and high elongation material can be applied to a semi-flexible part of a semi-flexible component carrier (especially a printed circuit board, PCB). This can allow small bending radii to be resolved and dynamic bending angles can be achieved on semi-flexible component carriers. In particular, this can be achieved by arranging a dielectric material in at least the semi-flexible part so as to have a low Young's modulus lower than 5 GPa and a high elongation higher than 3%. Therefore, the dielectric material in the semi-flexible portion can be elastic and malleable.

[0065]According to an exemplary embodiment of the present invention, a semi-flexible PCB is provided with a semi-flexible portion of a dielectric material, which has a low Young's modulus lower than 5 GPa and a high elongation higher than 3%. Traditionally, PCBs are only used for high bend radius applications with estimated radii gre...

Abstract

The invention discloses a semi-flexible component carrier (100). The semi-flexible component carrier comprises stack (102) comprising at least one electrically insulating layer structure (106) and/orat least one electrically conductive layer structure (104), wherein the stack (102) defines at least one rigid portion (108) and at least one semi-flexible portion (110); at least one electrically insulating layer structure (106') of the at least one electrically insulating layer structure (106) forming at least a portion of the semi-flexible portion (110) comprises a material having an elongationgreater than 3% and a Young's modulus less than 5 GPa. The invention also relates to a manufacturing method of the semi-flexible component carrier.

Description

Technical field[0001]The invention relates to a semi-flexible component carrier and to a method of manufacturing a semi-flexible component carrier.Background technique[0002]Product functions in component carriers equipped with one or more electronic components are increasing, and the miniaturization of such components continues to increase, and the number of components to be mounted on component carriers such as printed circuit boards In the context of increasing numbers, more and more powerful array-like components or packages with several components are used, which have multiple contacts or connections, and the spacing between these contacts or connections is getting smaller and smaller. Removal of the heat generated by these components and the component carrier itself during operation has become an increasingly serious problem. At the same time, the component carrier should be mechanically strong and electrically reliable in order to be operable even under severe conditions.[0003...
