  • Patent number: 10204845
    Abstract: A semiconductor chip package includes a semiconductor chip disposed over a main surface of a carrier. An encapsulation body encapsulates the chip. First electrical contact elements are electrically coupled to the chip and protrude out of the encapsulation body through a first side face of the encapsulation body. Second electrical contact elements are electrically coupled to the chip and protrude out of the encapsulation body through a second side face of the encapsulation body opposite the first side face. A first group of the first electrical contact elements and a second group of the first electrical contact elements are spaced apart by a distance D that is greater than a distance P between adjacent first electrical contact elements of the first group and between adjacent first electrical contact elements of the second group. The distances D and P are measured between center axes of electrical contact elements.
