RFID tag manufacturing method and RFID tag
First Claim
1. A method of manufacturing an RFID tag, comprising:
- forming a base sheet member that includes a first sheet member in tape form and unit base substrates on the first sheet member, wherein each of the unit base substrates is formed with a conductive pattern functioning as an antenna and has a non-contact communication-type circuit chipmounted thereon which is connected to the conductive pattern, and the unit base substrates are fixedly attached to the first sheet member with predetermined spaces along a direction of length ofthe first sheet member;
laminating a second sheet member and a third sheet member each in tape form elongating inthe direction of length of the first sheet member and having elastic properties, one upon another, in astate where reinforcing members for reinforcing the circuit chips are arranged between the secondsheet member and the third sheet member at the same space intervals as the space intervals at whichthe circuit chips are arranged, thereby forming an upper-layer sheet member, and laminating the upper-layer sheet member on a side of the base sheet member formed by said forming where eachunit base substrate is laminated, in a state where the reinforcing members are respectively alignedwith the circuit chips;
cutting out regions each including one of the unit base substrates sequentially from a sheetlaminate formed by said laminating, andforming openings in regions except the conductive patterns and the circuit chips, whereinone of the sheet members of the upper-layer sheet member and one of sheet members of a lower-layer sheet member toward the base substrate are fixedly attached to each other via theopenings in the unit base substrate.

Abstract
A method of manufacturing RFID tags. A base sheet member is formed by fixedly attaching unit base substrates to a belt-like first sheet member at predetermined space intervals. Each unit base substrate is formed with an antenna pattern and has a non-contact communication-type IC chip mounted thereon. An upper-layer sheet member is formed by arranging reinforcing members between elastic, belt-like second and third sheet members, and is laminated on a surface of the first sheet member toward the unit base substrates such that each IC chip and each reinforcing member overlap each other in plan view. Regions each containing one unit base substrate are sequentially cut out from a laminate of the upper-layer sheet member and the base sheet member, thereby making RFID units.

11. A method of manufacturing an RFID tag, comprising:
-
laminating on opposite surfaces of a base substrate in tape form having conductive patterns for functioning as antennas formed at predetermined space intervals in a direction of length of the base substrate, having non-contact communication-type circuit chips connected to associated ones of the conductive patterns mounted thereon, respectively, and further having openings formed in regions except the conductive patterns and the circuit chips, an upper-layer sheet member and a lower-layer sheet member each having a mesh-shaped reinforcing member arranged between two sheet members each having elastic properties in a sandwiched manner, wherein the mesh-shaped reinforcing member is wide enough to contain at least the circuit chips and elongates in a direction of length of the upper-layer sheet member and the lower-layer sheet member in a state where the mesh-shaped reinforcing member is located over the circuit chips, such that the sheet members of each of the upper-layer sheet member and the lower-layer sheet member are fixedly attached to each other, and that one of the sheet members of the upper-layer sheet member and one of the sheet members of the lower-layer sheet member toward the base substrate are fixedly attached to each other via the openings in the base substrate; and cutting out regions each containing one of the circuit chips and one of the conductive patterns connected to the one of the circuit chips and including at least part of the openings, sequentially from a laminate member which has the upper-layer sheet member and the lower-layer sheet member laminated one upon another with the base substrate therebetween. - View Dependent Claims (12, 13)
