  • Publication number: 20230116242
    Abstract: A thin form of an electrical connector for creating a detachable connection between two circuit elements is disclosed. When the connector is employed, only an outer electrode present on a portion of the connector is exposed to the ambient environment and the rest of the electronics of both the connector and of a device into which the device is integrated can be insulated from the ambient environment. The parts of the connector can create a small three-dimensional interlock structure to seal off contact area and to facilitate electrical contacts between two circuit elements. The connector structure is flexible, allowing the connector to be embedded into a curved surface of a device that can use the electrode exposed to the environment to obtain data regarding the environment.

  • Patent number: 11122683
    Abstract: Provided is a manufacturing process for electronic circuit components such as bare dies, and packaged integrated chips, among other configurations, to form electronic assemblies. The surface of the electronic circuit component carries electronic elements such as conductive traces and/or other configurations including contact pads. A method for forming an electronic assembly includes providing a tacky layer. Then an electronic circuit component is provided having a first side and a second side, where the first side carries the electronic elements. The first side of the electronic circuit component is positioned into contact with the tacky layer. A bonding material is then deposited to a portion of the adhesive layer that is not covered by the first side of the electronic circuit component, to a depth which is sufficient to cover at least a portion of the electronic circuit component. The bonding material is then fixed or cured into a fixed or cured bonding material, and the tacky layer is removed.

  • Patent number: 10847384
    Abstract: Development of smart objects with electronic functions requires integration of printed components with IC chips or dies. Conventional chip or die bonding including wire bonding, flip chip bonding, and soldering may not be applicable to chip or die attachment on low temperature plastic surfaces used in physical objects. Printing conductive connection traces requires a smooth interface between contact pads of a chip and the surface of the physical object. In order to address this issue of chip/die attachment to a physical object, this disclosure provides embodiments to construct a fixture on a chip or die for attachment and electrical connection onto a physical object by printing operations and/or ACF bonding methods.
