Hi Robert,

The answer to your question is yes, RFID can be used throughout the entire
assembly process, not only for PCBAs, and in some applications it offers
significant benefits over traditional barcode technology.

For PCB identification, RFID can be a good alternative because of their
durability, reliability and flexibility. In some applications even high
temperature barcode labels cannot survive the harsh environment. RFID also
enable higher levels of automation because RF tags and reader antennas can
be packaged in various shapes and sizes and because the read/write process
does not require a direct line of sight like barcode technology.

RF tags on PCBAs can be very cost-effective if they are used in a
closed-loop environment, by means of a temporary attachment to the board.
This enables automatic data acquisition throughout your operations and this
data can be linked to a unique serial number before the product is shipped
to your customer. You get all the benefits of RFID without the cost. In
general, permanent RF tags are only viable for high cost and high
reliability PCBAs that require complete traceability and where barcode
labels are not suitable.

Do not hesitate to contact me offline if you would like to discuss the
details of your specific application.

Subject: RF ID Tags for Electronic assemblies

We are a Contract assembler and we have a customer who is looking at using
RF Tags to identify their electronic assemblies instead of labels. Does
anyone have any experience with this type of technology for use on
Electronic Board asseblies? Can they be used throughout the entire assembly
process?
Any help would be appreciated.
Thanks,
Bob D.
