Manufacturing method for RFID tag
First Claim
1. A manufacturing method for an RFID tag, comprising:
- an application process in which a heat-curable adhesive is applied to an area where a circuit chip is placed on a base to which antennae are wired so as to be connected with the circuit chip to be placed;
a placement process in which the circuit chip is placed in the area where the adhesive is applied in the application process, and thereby the circuit chip is connected with the antennae;
a covering process in which the circuit chip placed on the base is covered with a sheet member having an adhesive layer on its surface, such that the adhesive layer faces the base; and
a heat and pressure applying process in which pressure is applied to the sheet member toward the base, and heat and pressure are applied to the circuit chip from above the sheet member, thereby curing the adhesive and fixing the circuit chip and the sheet member on the base;
wherein the application process is a process in which the adhesive is applied so that the quantity of adhesive is sufficient for the adhesive to be applied to a position equal to or exceeding a height of the circuit chip when the chip is placed on the base, and wherein the heat and pressure applying process is a process in which the heat and pressure are applied to the circuit chip and the sheet member by using a heat pressure head, the heat pressure head having a first surface corresponding to an area above the circuit chip, a second surface corresponding to an area outside of the circuit chip, extending and surrounding the first surface and higher than the first surface, and a third surface located inside the second surface and surrounding the first surface and lower than the first surface.

Abstract
An RFID tag manufacturing method is including application process in which a heat-curable adhesive is applied to an area where a circuit chip is placed on a base to which antennae are wired so as to be connected with the circuit chip, placement process in which the circuit chip is placed where the adhesive is applied, and thereby the circuit chip is connected with the antennae, covering process in which the circuit chip placed on the base is covered with a sheet member having an adhesive layer on its surface, such that the adhesive layer faces the base, and heat and pressure applying process in which pressure is applied to the sheet member toward the base, and heat and pressure are applied to the circuit chip from above the sheet member, thereby curing the adhesive and fixing the circuit chip and the sheet member on the base.
