基于rfid和藍牙的產品生命周期跟蹤

　　更強大的閱讀器相結合的轉發器，能夠承受回流焊已導致RFID越來越多地進入工作過程中的工作在電子制造監控。

　　除了傳統的RFID部署領域，如安全和考勤管理，RFID也已經進入了進程監控工作中。

　　一個這樣的應用是跟蹤印刷電路板（PCB）。直到最近，這個應用程序還是以條形碼和光學字符識別（OCR）為主。本文介紹了使用rfid跟蹤多氯聯苯的一些優點和要求，以及最近的產品如何使PCB跟蹤在整個生產過程中實現經濟實用。

　　Tracking PCBs

　　Electronics manufacturers want to be able to automatically identify individual PCBs in the production process. Being able to do so is valuable for a range of different tasks; such as configuration management， i.e.， the ability to manage several product variants and revisions in the same production process. It is also valuable for production testing and calibration.

　　The introduction of RFID for this purpose has taken some time. Even today， much of the tracking of PCBs in production is still done via barcodes or， in some cases， OCR. During the 1990s and most of the 2000s the lack of world standards， the cost and complexity of reading devices， the lack of robust performance， and the size and cost of practical transponders for use with PCBs prevented RFID from gaining substantial entry on the manufacturing floor.
