We use Fermi liquid theory to study the mechanical impedance of 3He-4He mixtures at low temperatures. The theory is applied to the case of vibrating wires, immersed in the liquid. We present numerical results based on a direct solution of Landau-Bolt

Why do we need to supply microvias? New components, such as thin small outline packages (TSOPs), chip size packages (CSPs) and direct chip attachment (DCA) are forcing designers to create new layouts which challenge the fabricator to manufacture prin
