A method to increase the damping of a substrate using a face-centered cubic ferromagnetic damping coating.

When soldering a package having an electrode on which Ni/Au or AgPd alloy is plated, to a printed circuit board having a Cu electrode or an electrode on which Cu is plated, a solid-phase diffusion layer is formed within a layered solder material for bonding different species of electrodes. The layered solder material is composed of a solder material of SnAgCu series or SnSb series and a solder material of SnAgCuNi series or SnPb series. The electrode on which Ni/Au or AgPd alloy is plated and the Cu electrode or the electrode on which Cu is plated are soldered with the solder material of SnAgCu series or SnSb series being attached to the Cu electrode and the solder material of SnAgCuNi series or SnCu series being attached to the electrode on which Ni/Au or AgPd alloy is plated. This restrains formation of intermetallic compounds and provides high bonding reliability.
