  • Patent number: 11814742
    Abstract: The present invention relates to a method of processing a component, wherein the component comprises at least one opening in a surface thereof, the method comprising: placing the component in an electrophoretic fluid comprising particles of a masking material as an electrode, applying a voltage to the component and a counter electrode of the component, depositing particles of the masking material in the electrophoretic fluid into the at least one aperture through electrophoresis to mask the at least one aperture; processing a surface of the component; and removing the masking material in the at least one opening.

  • Patent number: 11100268
    Abstract: Embodiments are generally directed to a hierarchical approach for performing simulation for PDNs that have integrated VRMs. According to certain aspects, embodiments include an approach that decouples the simulation for PDN and the simulation for VRM/PKG through PDN macromodeling. In these and other embodiments, the approach includes a SPICE-accurate simulation for the VRM part using a non-linear solver and using a linear solver for the PDN part, with minimal handshaking between them. For example, using a Backward Euler method having a fixed time step, at every simulation time interval, the linear solver sends reduced boundary currents to the non-linear solver. After the non-linear solver converges at the time interval, it sends boundary voltages back to the linear solver for determining voltages in the PDN part at the time interval.
