Patent ID: 7815122

Claim:
Method of making an electronic label comprising an electronic chip ( 1 ) provided with two contact strips ( 2 , 3 ) and an antenna formed from conducting wire ( 4 ), comprising: placing the chip ( 1 ) on a support piece so that the contact strips ( 2 , 3 ) of said chip are situated on the side opposite to that in contact with the support piece; taking conducting wire ( 4 ) from a reel and placing it on the support such that at least one portion is positioned facing the two contact strips of the chip ( 1 ); and welding the conducting wire ( 4 ) in a single welding operation onto the two contact strips ( 2 , 3 ) to form the antenna of the electronic label, wherein the welding of the conducting wire or wires ( 4 ) onto the contact strips ( 2 , 3 ) is done with a welding electrode ( 5 ) having an active portion with an end, and at the end of its active portion a recess ( 6 ), such that the recess ( 6 ) has a width that essentially corresponds to the gap between the two contact strips ( 2 , 3 ) enabling the welding electrode ( 5 ) to weld the antenna to the contact strip but not welding the wire in the gap between the contact strips.
