Taconic has over 35 years of experience coating fiberglass fabric with PTFE (polytetrafluoroethylene). This enables Taconic to manufacture copper clad PTFE/woven glass laminates with exceptionally well controlled electrical and mechanical properties.
Taconic TLY laminates are manufactured from woven fiberglass fabric coated wIth PTFE interleaved with thin sheets of pure PTFE. The woven matrix produces a more mechanically stable laminate with a more uniform dielectric constant (DK) than traditional non-woven products. The exceptionally low dissipation factor extends the usefulness of this product to 35 GHz and above.
The dielectric constant range is 2.17 to 2.40. For most thicknesses, the dielectric constant can be specified anywhere within this range with a tolerance of ± 0.02. In the low dielectric constant range, the dissipation factor is approximately 0.0009 when measured at 10 GHz.

TLY laminates can be sheared, drilled, milled and plat-ed using the accepted methods for PTFE/woven fiber-glass laminates. The laminates are dimensionally stable and are resistant to the solvents and reagents used during fabrication. TLY laminates are being used in composite multi-layer circuitboard applications.
Typical applications for TLY laminates include mobile communications systems, microwave transmission devices, phased array antennas, RF components, and automotive and military radars.
TLY laminates are generally ordered clad on one or both sides with 1/2, 1, and 2 oz. electrodeposited copper. Contact our Customer Service Department for alternate claddings.
Our TLY laminates meet the latest revision of IPC-L-125.
TLY laminates are tested in accordance with IPC-TM-650. A certificate of compliance containing lot-specific test data accompanies each shipment.
