TLY-5Z Low DK/Low Z Axis Expansion/Low Density Laminates Technical Data Sheet
●TLY-5Z laminates are advanced, glass-filled, PTFE composites with woven fiberglass reinforcement. The glass-filled structure was designed for low density applications such as aerospace having optimally low weight requirements. This results in a dimensionally stable composite which is otherwise not possible with non reinforced PTFEs. The 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. The glass-filled structure is a cost-effective 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 difficult to manufacture or thermally unreliable with conventional PTFE-rich substrates. Often, plated through holes in conventional PTFE-rich substrates suffer from drilling defects and must be plated with thick copper to have any hope of reliability. These PWBs may suffer from thermal cycle induced cracks. TLY-5Z has half the thermal expansion of PTFE-rich substrates, offers improved drilling and can be thermally cycled. Ground stitching along transmission lines can be readily accomplished and they will be thermally reliable. TLY-5Z offers 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 flattest of coppers such as the new ULP ultra low profile copper foils.
