Abstract

PURPOSE: To simplify resin-filling process and also to reduce volume of resin in use by covering surrounding of a wire, including an electrode section, with high- purity liquid resin while a wire is being connected to the electrode.
CONSTITUTION: At first, a wedge 1 is lowered on a semiconductor part 5 piled on a supporting table 4, and while keeping a resin-coating step 3 separated from a wire 2, the wire 2 is pressingly attached securaly to No.1 electrode 51. At the time when the wedge 1 is raised, a resin flow guide 33 of the resin coating step 3 is lowered to such an extent that its top end contacts the wire 2, and while the wedge 1 is shifting, liquid resin 31, equivalent in volume to air poured into a container 32 through a pipe 34, is made to flow onto stick-out sections of the electrode 51 and the wire 2. The wedge 1 is again lowered above an electrode 52 and the resin coating step 3 is raised, and while keeping the guide 33 separated from the wire 2, the wire 2 is fixed onto the electrode 52. After the wire 2 is cut off, the electrode 52 is also covered with resin by shifting of liquid resin 31.
