The document summarizes RFID tag production at Company X using equipment from Tyco. It describes initial issues with the production process but how the process was optimized over time through modifications to the equipment and procedures. Key changes included increasing the size of conductive epoxy dots from 20 mil to 40 mil, redesigning RFID antennas and attachment nozzles to improve strap attachment, and continuously monitoring production metrics to ramp up capacity. The production using the Tyco equipment grew from initial low output to producing over 2,000 feet and 1,000 RFID tags per day by optimizing the automated process.
2. What is RFID?
• RFID stands for Radio-Frequency IDentification. The acronym refers to small
electronic devices that consist of a small chip and an antenna. The chip typically is
capable of carrying 2,000 bytes of data or less.
• The RFID Tag device serves the same purpose as a bar code or a magnetic strip
• RFID tags may be of one of two types.
– Active RFID tags have their own power source
– Passive RFID tags, do not require batteries and can be much smaller
4. The strap is then attached
to a metallic antenna and
attached to an adhesive
label – making an RFID tag
3. Metal is printed on the
substrate to connect to
the chip, creating a Strap

4. • A Radio-Frequency IDentification System has three parts:
– A scanning antenna
– A transceiver with a decoder to interpret the data
– A transponder - the RFID tag - that has been programmed with information.
• The scanning antenna puts out RF signals that does two things:
– It provides a means of communicating with the transponder (the RFID tag) AND
– It provides the RFID tag with the energy to communicate. When an RFID tag passes
through the field of the scanning antenna, it detects the activation signal from the
antenna. That "wakes up" the RFID chip, and it transmits the information on its
microchip to be picked up by the scanning antenna.
How does RFID work?
5. Brief History of the Tyco RFID Web Production
Equipment & Tyco Support @ Company "X"
• Early 2006 - Tyco started new RFID Web Production Division to compete with others
• Mid 2006 –Company "X" enters into contract with Tyco for a small RFID Web Assembly set of equipment with
the hope & opportunity to expand to multiple units and/or more complete production lines. Tyco equipment must
meet a specific Parts/hour placement prior to "buy off".
• Late 2006/Early 2007 - Tyco & "X" start working together on the Development of "X"s system. Defining and
engineering some of the "uniqueness" from a Surface Mount process to a Web based process.
• Early 2007 - Tyco SUPPORT for the RFID Web Systems Division is:
1. Sales person
2. Full Engineering, both Mechanical, Electronic & Soft Ware support
3. Full Field Service support.
4. All integration & further Development!
• mid 2007 - Tyco spins off Tyco Ltd which inherits the RFID Web Systems. Mike Trubilla takes over as Process
engineer for “X”.
• Early 2008 - "X" "signs off Tyco purchase after moderate success with Transit Card production, why the system
was originally purchased. Confusion on materials and expectations was resolved & proved in and then after
required production output for "sign off".
• Tyco "claims" a "Hugh" profit loss in the deal. “Writing on the wall”, is they want out!
Tyco then "Shuts down" the RFID Division with no notice???.
• Early 2008 – Mike Trubilla at "X" gets Training 4/2008 from Tyco and takes over the major support of the Tyco
System and is allowed phone call support. Tyco "stops" all future engineering support and Field Service is
realigned.
7. • Mid 2007 (prior to Mike) - initially production started with only one
product at ~ 200 tags/hour on a very limited daily basis.
Approximately averaging 2 to 3 hours/day or ~ 15 hours/40 hour
week.
• September 2007 through to early December 2007. Production
quickly ramped up when the majority of the production problems
had been resolved. >200 Tags/hour for >30 hours/week
• In the March/April 2008 timeframe, as one product was reducing in
daily production, new products replaced the capacity until one new
product dominated the production requirements starting in May/June
timeframe. In late July a 2nd
shift was put into place and then
September 2008 a 3rd
shift was trained and brought online.

• Gap for Cure Oven, ~24” & oven =

• What's important is that this is
“perfectly’ parallel to the QSP-2 as
well as to the laminator and Re-
Winder to keep the web equally
tight and not “walking” to one side.
• Ideally the QSP-2, Vacuum roll-
bar, laminator & the Re-Winder
should be on a “two rails” to keep
them perfectly parallel.
• Overall this unit looks good.
• Possibly change the size &
amount of vacuum holes – smaller
and more to prevent wrinkles in
the 2 mil PET.

17. Initial work to resolve the poor
performance of the RFID tag
manufacturing with the Tyco
System.
18. First major problem that had to be resolved from the previous engineers work
and was a major roadblock to dramatically increase production and provide
adequate capacity was the idea that the process required pushing the physical
capability of the mechanical chemical dispensing system to attain 20 mil dots
of conductive epoxy to provide the following:
1. adequate adhesion,
2. minimal/enough contact resistance
3. and not risk creating conductive epoxy shorts in the Tags coils and IC
Strap attachment due to strap compression on the epoxies.
After discussions with the technical personnel who formulated this requirement
when they initially worked with Tyco and set the acceptance parameters of the
RFID Tag Equipment set, and then reviewing both the equipment capabilities,
the RFID tag dimensions, the IC strap dimensions, the question was asked –
•Why 20 mil dots? Why not try 40 mils instead or can they be larger?
19. This was then properly evaluated by working with the equipment
vendors and the process was refined along with hardware
modifications to the point that this major process problem was
eliminated.
20. 5/16/08 - Tyco Assembly – CAC dispense dots after re-tune & rebuild
of pump.
21. Re-designs of the RFID Antennas was put into place to further
enhance and support the new epoxy dispense process, which actual
produced a more robust strap attach process.

22. Additionally a Re-design of the Tyco nozzle that places the straps on the
antennae was put into place after discovery of another initial design flaw that
allowed/produced poor compression of the strap into the conductive epoxy.
This was creating a reliability problem in the field with poor electrical contact.

24. Instructions, Non-conforming problems, experiments,
evaluations and capacity ramps with upgrades were
continuously provided as the manufacturing demand
increased:
1. Equipment(1) & Operator(2) Instructions(3)
2. Manufacturing & Engineering Training – last Tyco training support
3. Operator Safety – laminator exhaust
4. Upgrades for more Capacity – ROI and support memo
5. Reduce equipment issues - PMs
6. Corrective Action reports to Vendors – NXP strap supplier issue
7. Capacity Ramp up plan – Tyco equipment upgrades/changes
8. New supplier evaluations – Antennae Web printing
25. As production was ramped, various metrics
and process performance tools were
continuously being put into place to control
and monitor Company “X”s manufacturing
success:
1. Output’s – provide Intervals & Capacities
2. Pareto’s - Scrap reduction & Targets for improvements
3. Expenses – supply cost reductions, inventory control
