RFID tags that incorporate Printed Circuit Board
technology are designed for encasement inside totes,
pallets, or products that can provide the protection
normally associated with injection-molded
enclosures.
These tags are made primarily from
etched copper PCB materials (FR-4, for
example) and are die-bonded by means
of high quality wire bonding. This
procedure ensures reliable electrical
connections that are superior to flip-chip
assembly methods. The RFID tag's integrated
circuit is then encapsulated in epoxy to protect
it and the electrical connections.

Molded tags utilize PCB tags and are the most rugged and reliable of the tags offered
by Escort Memory Systems. These tags are designed for closed-loop applications
where the tag is reused; thereby the cost of the tag can be amortized over the life of
the production line. Typically, molded tags will be mounted to a pallet or carrier that
transports (and accompanies) the product through the entire production process.

Other applications for these tags include (but
are not limited to) embedding tags within
concrete floors for location identification, shelf
identification for storage and retrieval systems,
and tool identification.
Escort Memory Systems offers a wide variety
of molded tags that have been developed over
the years for real world applications. High
temperature tags using patented processes
and specialized materials allow tags to survive
elevated temperatures, such as those required
for automotive paint and plating applications.
