基于rfid和蓝牙的产品生命周期跟踪
更强大的阅读器相结合的转发器，能够承受回流焊已导致RFID越来越多地进入工作过程中的工作在电子制造监控。
除了传统的RFID部署领域，如安全和考勤管理，RFID也已经进入了进程监控工作中。
一个这样的应用是跟踪印刷电路板（PCB）。直到最近，这个应用程序还是以条形码和光学字符识别（OCR）为主。本文介绍了使用rfid跟踪多氯联苯的一些优点和要求，以及最近的产品如何使PCB跟踪在整个生产过程中实现经济实用。
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.
