RFID TAG INCORPORATING TEMPERATURE SENSOR AND IC PACKAGE SUBSTRATE HAVING TEMPERATURE SENSOR

PROBLEM TO BE SOLVED: To provide an RFID tag incorporating a temperature sensor, which, without a battery, has excellent followability relative to even articles with various shapes so as to be able to adhere to them and also prevents failure in communication.SOLUTION: An RFID tag 10 incorporating a temperature sensor includes: an IC package substrate 4 having a temperature sensor, in which an IC package 2 having the temperature sensor is mounted on a circuit board 3; and an antenna substrate 9 for communicating with an external device. The IC package substrate having the temperature sensor and the antenna substrate are electrically connected with each other by lead wires 6. In the IC package substrate having the temperature sensor, the IC package having the temperature sensor is mounted on the circuit board by using solder 7. A through hole 11 is formed in an area where the IC package having the temperature sensor is mounted on the circuit board. The solder is filled between the IC package having the temperature sensor and the circuit board. A surface opposite to the IC package having the temperature sensor in the circuit board is covered also by the solder.SELECTED DRAWING: Figure 1 【課題】本発明はバッテリーレスで、様々な形状の物品にも追従性が良く密着可能で、通信不能になることが無い温度センサを内蔵したＲＦＩＤタグを提供することを課題とする。【解決手段】温度センサ付ＩＣパッケージ２を回路基板３に実装した温度センサ付ＩＣパッケージ基板４と、外部装置との通信を行うためのアンテナ基板９と、を備えており、温度センサ付ＩＣパッケージ基板とアンテナ基板とは、リード線６によって電気的に接続されており、温度センサ付ＩＣパッケージ基板は、回路基板に温度センサ付ＩＣパッケージがはんだ７を用いて実装されており、回路基板の温度センサ付ＩＣパッケージが実装される領域には、貫通孔１１が形成されていり、温度センサ付パッケージと回路基板間にははんだが充填されており、回路基板の温度センサ付パッケージ側と対向する面もはんだによって被覆されていることを特徴とする温度センサを内蔵したＲＦＩＤタグ１０。【選択図】図１
