  • Patent number: 10879583
    Abstract: An electronic device includes a support plate having a mounting face and an electrical connection network. An integrated circuit chip is mounted on the mounting face and linked to the electrical connection network. An encapsulation block embeds the integrated circuit chip. An additional element made of an electrically conductive material is at least partly embedded within the encapsulation block. The additional conductive element has a main portion extending parallel to the support plate and has a secondary portion that is linked electrically to the integrated circuit chip. An opening is formed in the encapsulation block, and the secondary portion extends into that opening to make the electrical link. The additional conductive element may be an antenna.

  • Patent number: 10292259
    Abstract: An electronic device disclosed herein includes a first conductor layer, a first nonconducting layer, and a second conductor layer in a stacked arrangement. A signal carrying conductive via is formed in the first nonconducting layer and extends between the first conductor layer and the second conductor layer. A shielding conductive via is formed in the first nonconducting layer, is not electrically coupled to the signal carrying conductive via, and substantially completely surrounds the signal carrying conductive via in spaced apart relation thereto.

  • Patent number: 10103079
    Abstract: An electronic device includes a supporting substrate having a front mounting face and an electrical connection network. An integrated circuit chip is mounted to the mounting face and is electrically connected to the electrical connection network. A primary encapsulation block embeds the integrated circuit chip and extends above and around the integrated circuit chip on the mounting face of the supporting substrate. An opening is provided in the primary encapsulation block to at least partially uncover an electrical contact. An additional wire made from an electrically conductive material has an end that is electrically connected to the electrical contact. An additional encapsulation block above the primary encapsulation block embeds the additional wire.

  • Patent number: 10062961
    Abstract: An electronic device includes a support board having a mounting face and an integrated circuit chip mounted on the mounting face. An encapsulation block embeds the integrated circuit chip, the encapsulation block extending above the integrated circuit chip and around the integrated circuit chip on the mounting face of the support board. The encapsulation block includes a front face with a hole passing through the encapsulation block to uncovering at least part of an electrical contact. A layer made of an electrically conducting material fills the hole to make electrical connection to the electrical contact and further extends over the front face of the encapsulation block.
