Introducing TLG-30, TLG-32, TLG-34 & TLG-35

TLG, Taconic's bromine free high performance product line, is the result of Taconic's expertise and extensive experience in providing the circuit board market with state-of-the-art high-performance laminate materials.

Our unique combination of materials and processes allows us to lower our manufacturing cost and give our customers a high performance laminate material at a very competitive price.

TLG is offered with DKs of 3.0, 3.2, 3.38 and 3.5 with a tolerance of +/- 0.05. Using PTFE building blocks gives TLG a low dissipation factor of 0.0026 - 0.0030 when measured at 10 GHz.

TLG exhibits a linear z-axis CTE up to the material's melt point of over 315 °C. Using TMA testing, TLG has no discernible Tg point on the TMA curve until its melt point. Because of its woven glass reinforcement, TLG has excellent x/y dimensional stability.

Due to TLG's composition, it can be manufactured with copper that has a much lower tooth profile than competitive microwave materials, while still attaining good peel strength.

TLG materials can be sheared, drilled and milled using the accepted methods for PTFE/woven glass laminates. Plating of through holes requires treatment of the hole walls using a plasma epoxy desmear or permanganate cycle and either a plasma fluoropolymer treatment or sodium treatment. TLG has low moisture absorption and is very resistant to solvents and reagents used during manufacturing. 

For multilayer applications, TLG is also available as a prepreg - designated as TacPreg.

TLG laminates are generally ordered clad on both sides with 1/2 or 1 oz electrodeposited copper. 

TLG laminates are tested in accordance with IPC-TM 650. A certificate of compliance containing lot-specific data accompanies each shipment.
