  • Publication number: 20240076488
    Abstract: Provided herein is an electrically conductive composition capable of sintering. More particularly, the electrically conductive composition comprises sinterable silver particles dispersed in a binder resin, which binder resin is not yet in a fully cured state when the composition is heated to a temperature at which the silver particles start to sinter.

  • Patent number: 10985108
    Abstract: Provided herein are conductive formulations which are useful for applying conductive material to a suitable substrate; the resulting coated articles have improved EMI shielding performance relative to articles coated with prior art formulations employing prior art methods. In accordance with certain aspects of the present invention, there are also provided methods for filling a gap in an electronic package to achieve electromagnetic interference (EMI) shielding thereof, as well as the resulting articles shielded thereby. Specifically, invention methods utilize capillary flow to substantially fill any gaps in the coating on the surface of an electronic package. Effective EMI shielding has been demonstrated with very thin coating thickness.

  • Patent number: 10858523
    Abstract: Provided herein are highly conductive compositions (having a volume resistivity no greater than 1×10?3 Ohms·cm) using silver flake, powder or suspension in solvent for electromagnetic interference (EMI) applications. This high conductivity will allow the use of very thin films for EMI shielding protection, which in turn will be helpful to reduce package sizes. In some embodiments, the coating composition is applied on the device surface by suitable means, e.g., by an electrostatic spray process, air spray process, ultrasonic spray process, spin coating process, or the like.

  • Patent number: 10741503
    Abstract: Provided herein are conductive formulations wherein graphene has been added into the metal system, thereby reducing curing shrinkage and improving flexibility, without significantly affecting the EMI shielding performance thereof. In accordance with certain aspects of the present invention, there are also provided methods for filling a gap in an electronic package to achieve electromagnetic interference (EMI) shielding thereof, as well as the resulting articles shielded thereby. In certain aspects of the present invention, there are also provided articles prepared using invention formulations and methods.
