TLY
laminates are manufactured with very lightweight woven
berglass and are much more dimensionally stable than
chopped ber reinforced PTFE composites. e woven matrix in the
TLY material yields a more mechanically stable laminate that is suitable
for high volume manufacturing. e low dissipation factor enables
successful deployment for automotive radar applications designed at
77 GHz as well as other antennas in millimeter wave frequencies.
Comparative OEM testing at 77 GHz of lightly reinforced TLY-5 vs.
its closest chopped ber reinforced competitor has shown “drop in”/
equivalent insertion losses/dielectric properties. e primary benet
is much higher manufacturing yields.
e dielectric constant range is 2.17 to 2.40. For most thicknesses,
the dielectric constant can be specied anywhere within this range
with a tolerance of +/- .02. In the low dielectric constant range, the
dissipation factor is approximately 0.0009 at 10 GHz.
Typical applications include satellite communications, automotive
radar, lters, couplers, avionics and phased array antennas.
Newer lightweight berglass TLY products have been introduced for
better laser hole quality (TLY5-L-0040). TLY products with enhanced
exibility have been designed for fabrication of antennas that have
some curvature (TLY-3FF).
Taconic is a world leader in RF laminates and high speed digital
materials, oering a wide range of high frequency laminates and
prepregs. ese advanced materials are used in the fabrication of
antennas, multilayer RF and high speed digital boards.

TLY Family of Low Loss Laminates
Flexible Laminates
TLY-3FF
is a new highly exible laminate
designed for applications that
require laminates with some bend radius. TLY-3FF is much
more exible than standard TLY berglass reinforced
substrates. e exibility of TLY-3FF is comparable to
chopped ber reinforced PTFE laminates yet it has a
loss tangent that is lower than traditional chopped ber
reinforced laminates.
e berglass reinforced TLY-3FF has been engineered to
provide the dimensional stability typical of the standard
berglass reinforced TLY Series yet oers the mechanical
exibility of chopped ber reinforced laminates.
TLY-3FF has also been designed for improved laser via
formation relative to traditional TLY glass reinforced
laminates.
e suggestion that chopped ber reinforced 2.2 laminates is truly random is optimistic and perhaps misleading. Visual
observation of a 5 mil chopped ber 2.2 laminate shows a non homogeneous appearance with dark and light colored areas
(Figure A). To determine the uniformity of the chopped ber reinforcement, X-Ray Fluorescence was used. e chemical
composition of berglass is dominated by silicon oxide (SiO
2
), followed by CaO
2
, Al
2
O3, MgO and B
2
O
3
. XRF is more
sensitive to the heavier elements than carbon or uorine. For this reason, XRF was used to trace the relative compositions
of the heavy Si and Ca in the light and dark regions. e rst observation was that the dark and light regions had dierent
densities (surface analysis not shown). e intensity of the scattering is proportional to the concentration of light vs. heavy
elements. A more detailed analysis would be necessary to yield quantitative information on the dierence in densities
between the two regions. It is well known that the Dk of PTFE is dependent on the amount of air that is compressed out of
a PTFE composite during high temperature densication. Figure B shows an overlap of the XRF scattering intensities for
the light and dark colored regions (subsurface bulk anaylsis). e dark region shows 2.35 times the amount of silicon and
1.34 times the amount of calcium in the dark regions. Silicon oxide (silica) has a Dk of 3.28 and is appreciably higher than
the 2.1 Dk of PTFE. e non uniform distribution of the silicon and calcium suggests that the manufacturing process is
prone to producing non homogeneous dielectric materials. It is unknown at this time which material is more homogeneous
- chopped ber or continuous weave reinforced 2.2 Dk PTFE composites. ough it must be stated that the domain sizes
of the light and dark regions are very large and visible to the naked eye on the chopped ber laminate and certainly on par
with woven berglass PTFE laminates (TLY-5). Truly random chopped ber reinforced laminates would have equal x, y and
z CTE values. e large domain sizes of light and dark colored areas with dierent Si and Ca concentrations would suggest
that there are probably dierent domains within the laminate of uctuating CTE values.
