    Abstract: The present invention relates to an electric and/or electronic circuit including a printed circuit board (20), at least one separate circuit board (10) and at least one power connector (12) for said printed circuit board (20). The at least one power connector (12) is connected or connectable to a corresponding counterpart. A number of electric and/or electronic components (22) is sold at the separate circuit board (10). The at least one separate circuit board (10) is connected to the printed circuit board (20) by a number of solder joints (16). The solder joints (16) are connected to the separate circuit board (10) by a through-hole-technology. The solder joints (16) are connected to the printed circuit board (20) by SMD (surface mount device) technology. At least one power connector (12) is fastened at the separate circuit board (10) by the through-hole-technology.

    Abstract: A composition for forming transition vias and transition line conductors is disclosed for minimizing interface effects at electrical connections between dissimilar metal compositions. The composition has (a) inorganic components selected from the group consisting of (i) 20-45 wt % gold and 80-55 wt % silver and (ii) 100 wt % silver-gold solid solution alloys, and (b) an organic medium. The composition may also contain (c) 1-5 wt %, based upon the weight of the composition, of oxides or mixed oxides of metals selected from the group consisting of Cu, Co, Mg and Al and/or high viscosity glasses mainly containing refractory oxides. The composition may be used as a multi-layer composition in a via fill. Multi-layer circuits such as LTCC circuits and devices may also be formed using the composition for forming transition vias and transition line conductors.
