Abstract

A breakaway RFID tag is configured such that it comprises part of a Printed Circuit Board Assembly (PCB). Thus, the breakaway RFID tag can be used to track the PCB as it migrates through a manufacturing process. In one embodiment, the RFID tag can be assembled first and then used to track the PCB as it is populated with components and installed into larger assemblies and ultimately into the end device. Once the PCB is installed into a larger assembly or the end device, the breakaway RFID tag is configured such that it can be broken off and attached to the outside of the larger assembly or end device.

First claim

What is claimed is:

1. A trackable printed circuit board (PCB), comprising:
a main circuit area which is manufactured through a PCB process including a plurality of processing steps;
a breakaway radio frequency identification (RFID) tag disposed on the PCB, the breakaway RFID tag comprising a printed antenna and an integrated circuit (IC) pad configured to receive a RFID transponder IC, wherein the plurality of processing steps include a repair step for performing a repair operation on the trackable PCB at a repair station; and
a breakable portion connecting the main circuit area and the RFID tag, wherein the breakable portion is configured to allow the breakaway RFID tag to be detached from the main circuit area.

2. The trackable PCB of claim 1 , wherein the breakaway RFID tag is scanned before each of the plurality of processing steps.

3. The trackable PCB of claim 1 , wherein the breakaway RFID tag is scanned after each of the plurality of processing steps.

4. The trackable PCB of claim 1 , wherein the plurality of processing steps include one or more assembly steps for assembling multiple components onto the main circuit area.

5. The trackable PCB of claim 1 , wherein the breakaway RFID tag is configured to be scanned during the PCB process when the breakaway RFID tag is attached to the main circuit area and store information associated with the plurality of processing steps.

6. The trackable PCB of claim 5 , wherein the breakaway RFID tag is scanned when the trackable PCB enters the repair station.

7. The trackable PCB of claim 5 , wherein the breakaway RFID tag is scanned when the trackable PCB exits the repair station.

8. The trackable PCB of claim 1 , wherein the stored information includes identification information of the breakaway RFID tag and a time when the breakaway RFID tag is scanned.

9. The trackable PCB of claim 1 , wherein the breakaway RFID tag is configured to be detached from the main circuit area and attached to an exterior of an assembly comprising the PCB.

10. The trackable PCB of claim 1 , wherein the breakaway RFID tag further comprises an RFID transponder disposed on the IC pad.

11. The trackable PCB of claim 1 , wherein the breakable portion is perforated with holes so that the breakaway RFID tag can be snapped-off from the trackable PCB.

12. The trackable PCB of claim 1 , wherein the breakaway RFID tag comprises a passive RFID tag.

13. The trackable PCB of claim 1 , wherein the breakaway RFID tag comprises an active RFID tag.

14. The trackable PCB of claim 1 , wherein the printed antenna and IC pad are disposed on the breakable portion.

15. The trackable PCB of claim 1 , wherein the breakaway RFID tag is configured to store tracking information associated with the plurality of processing steps.

16. The trackable PCB of claim 1 , wherein the breakaway RFID tag is configured to store repair information of the repair operation performed on the trackable PCB at the repair station.
