Self Supported Coils: Custom Coil Winding Using Small Gauge Wire
|
|
CWS specializes
in very complicated and very delicate custom windings of self
supported coils. We can wind extremely small diameter wires, down
to 0.04mm ( 1.5 mils) in diameter. These self supported coils
are usually wound on self bondable wires, but they can also be
wound on non self bondable wires such as the class 200 deg C wires
and then bonded with epoxy. CWS also wind large self supported
coils over 300mm ( 12 ") in lengths and widths. Application
includes sensors, RFIDs, industrial, medical and military. Very
low cost, million pieces volume windings are done at our Asian
facility.
Examples of
custom coil windings from CWS for RFID applications are:
1) Smart
Card Coils for 125 kHz or 13.56 MHz: Please see image below
for more description.
2) Clamshell
Coils: These are thicker coils than the Smart Card coils.
The thickness is approximately 1 mm ( 40 mils) . The copper wire
diameter ranges from 0.064mm ( 2.5 mils) to 1.0 mm ( 40 mils).
Oval or round shaped depending on custom requirements. The coil
inductance is designed to match the module inductance for 125
kHz or 13.56 MHz resonance frequency.
3) Proximity
Cards Coils: For 125 kHz or 13.56 MHz resonance frequency.
Coil inductance designed to match the module capacitance. Thickness
of 1.6mm ( 63 mils). Modules includes Hitag, Mifare, Temic or
any customized module. The read range is approximately 5 cm to
15 cm depending on the types of reader used. Oval shaped coils
are used to maximize the reading distance.
4) Other
Services: Coil to module attachment. Coils are soldered to
modules using thermo compression welding. Ideal for Smart Card
lamination process. No solder is involved to eliminate added height
due to solder. CWS also provide complete tag assembly using ultra
sonic welding for plastic casing.
See
below for examples of custom coil windings. Please call CWS for
your requirements - high quality work at a reasonable tooling
cost and low cost volume production.

7"
x 4" self supported coils using AWG #20 wire.
Built
to customer's specifications using Butyl or Epoxy bondable wires.
CWS
can also wind these using non bondable wires for extremely high
temperature applications.

Smart
Card Coils:
Very
thin and flat coils for smart card lamination process. Thickness
ranging from 0.20mm to 0.30mm. Ideal for ISO card standard.
Very fine copper wires with diameters of 0.04mm to 0.15mm are
used. Oval or round shape. The coil inductance is matched with
the module capacitance for 125 kHz or 13.5 kHz resonance frequency

Round
Coils :
Self
supported round or oval shaped coils with any wire gauge down
to AWG #40. Single wire diameter layer or multiple wire diameter
layers. CWS built to customer's specifications.
