PURPOSE:To simplify batch treatment for a connection of a lead wire to a small-sized element, to improve yield and to enhance mass-producting capability by using a specific jig. CONSTITUTION:A jig 6 has a plurality of recessed sections 7, 8 for fitting elements 1 to both the surface and the back m1, m2, a plurality of first grooves 9, 10 crossing on bottoms of the recessed sections 7, 8, a plurality of second grooves 11, 12 crossing in the upper-end openings of the recessed sections 7, 8 and vacuum suction holes 13 on bottoms of the recessed sections. First lead wires 15 are inserted into the first grooves 9, 10 in succession, a vacuum pump 14 is operated, and the elements 1 coated with solder 18, 19 are inserted one by one and sucked under a vacuum. Second lead wires 16 are inserted into the second grooves 11, 12 in succession, and the evacuation of the vacuum suction holes 13 is stopped. The whole is passed through a heating furnace to melt the solder 18, 19 on the elements 1, and the lead wires 15, 16 are soldered collectively on each element 1. |
