    Abstract: An electric contact using resin solder is connected to a printed circuit board without requiring soldering work. The circuit board has a conductor on a surface or in an intermediate layer thereof, and a through hole or a concaved part that penetrates the conductor. The electric contact includes a protruding part, which is inserted into the through hole or the concaved part, and a connecting part, which is connected to a conductor of a counterpart member such as a counterpart second circuit board. At least a part of the protruding part that connects to the conductor of the printed circuit board is made of a lead-free ultrahigh-conductive plastic resin composite. An electric connector includes the electric contact and an insulating housing, which holds the electric contact so that the protruding part and the connecting part thereof protrude outwardly.

    Abstract: A method for increasing the manufacturing certainty of soldered connections between a ceramic carrier and a printed-circuit board. It includes the method step of applying a first decomposition-resistant metallization layer on a ceramic carrier and the subsequent imprinting onto the first metallizing layer of a second metallizing layer, improving the wetting performance. In this manner, it is possible to achieve an increase in the overall metallizing layer thickness in the edge area of a soldered connection, whose solder rise in turn makes possible an optical, fully-automatic monitoring of the soldered connection.

    Abstract: Provided are a bonded structure by a lead-free solder and an electronic article comprising the bonded structure. The bonded structure has a stable bonding interface with respect to a change in process of time, an enough strength and resistance to occurrence of whiskers while keeping good wettability of the solder. In the bonded structure, a lead-free SnnullAgnullBi alloy solder is applied to an electrode through an SnnullBi alloy layer. The SnnullBi alloy, preferably, comprises 1 to 20 wt % Bi in order to obtain good wettability of the solder. In order to obtain desirable bonding characteristics having higher reliability in the invention, a copper layer is provided under the SnnullBi alloy layer thereby obtaining an enough bonding strength.
