<p><P>PROBLEM TO BE SOLVED: To provide a connecting device capable of electric connection of electric components without using solder, since the solder is an alloy with lead and tin as main ingredients whose use tends to be forbidden, although many of the electric components are mounted by soldering. <P>SOLUTION: A plasma generating device is provided for generating surface wave plasma in a reducing atmosphere of hydrogen gas by supplying hydrogen gas together with microwave power in a treatment room. After an electric connection terminal 22 with oxide films 24, 25 formed and a printed circuit 23a are jointed to have a connector 20 arranged on a printed circuit board 23, the printed circuit board 23 is housed in the treatment room to be exposed to the surface wave plasma, and then, the above oxide films 24, 25 and stains are reduced to have the electric connecting terminal 22 connected to the printed circuit 23a, and the connector 20 is mounted on the printed circuit board 23. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
