TLY-5Z
laminates are advanced composites
consisting of ceramic, PTFE and a woven
berglass reinforcement. e composite structure was designed
for low density applications such as aerospace having optimally
low weight requirements. e combination of ceramic and woven
berglass results in a dimensionally stable composite which
is otherwise not possible with non reinforced PTFEs. e low
density approach also makes for a composite with a low Z axis
expansion which is also not otherwise possible with PTFE-rich
composites. TLY-5Z is much more thermally stable with respect
to z axis expansion induced stress on plated through holes than
conventional low dielectric constant PTFE-composites.
TLY-5Z is also an attractive choice from a cost perspective. e
ceramic/berglass structure is a cost-eective solution versus
standard PTFE-rich copper clad laminates. TLY-5Z can be used
in high volume commercial microwave applications where PTFE-
rich substrates would be cost prohibitive. TLY-5Z can be used in
PWB designs which would be extremely dicult to manufacture
or thermally unreliable with conventional PTFE-rich substrates.
Oen, plated through holes in conventional PTFE-rich substrates
suer from drilling defects and must be plated with thick copper to
have any hope of reliability. ese PWBs may suer from thermal
cycle induced cracks. TLY-5Z has half the thermal expansion
of PTFE-rich substrates, oers improved drilling and can be
thermally cycled. Ground stitching along transmission lines can
be readily accomplished and they will be thermally reliable. TLY-
5Z oers a much better option for complex multilayer stripline
design than older PTFE rich substrates. TLY-5Z can support
Substrate Integrated Waveguide (SIW) applications with many
mode suppression vias.
TLY-5Z can be combined with the attest of coppers such as the
new ULP ultra low prole copper foils.

TLY-5Z shows reduced temperature coecient of dielectric constant (TcK) relative to conventional 2.2 dielectric
constant materials.
PIMD (Passive Intermodular Distortion) occurs in complex communications systems where multiple frequen-
cies induce unwanted harmonic distortion. PIM can result from many sources other than the copper clad
laminates. However, laminates such as Taconic’s TLY and TLY-5Z exceed PIM requirements of PCBs of -153 dBc
(measured between 880 and 960 M, from 1710 to 1880 MHz and from 1920 to 2100 MHz). Data was collected
using 20 Watt signal carriers and reverse treated copper (CL1).
TLY-5Z’s improved PTH reliability results in consistent PIMD levels in pwb designs with plated through holes
even aer repeated thermal cycling.
