Ventec launches VT-5A2: Next Generation, Best-in-Class High Tg Thin-Core and Pre-Preg Material

Ventec International is adding to its extensive thermally conductive laminate and pre-preg range with the launch of the VT-5A2, a next generation best-in-class, high Tg thin-core and pre-preg material.

 VT-5A2 is designed for the world’s most thermally demanding PCB (Printed Circuit Board) applications such as power converters, hybrid multilayers and high power electronics with heavy copper designs providing enhanced signal stability in harsh environments. With VT-5A2, Ventec has created its highest performance thermally conductive laminate material so far, with a polymer matrix that is fully compatible with Ventec laminates, Epoxy or Polyimide based materials including tec-speed®, thus allowing total compatibility in the manufacture of hybrid multilayer boards.

With a thermal conductivity 8 times that of FR4, VT-5A2 delivers class-leading thermal performance and high flow-ability for perfect encapsulation; this enables better board design for applications requiring critical thermal management in harsh environments. Customers can choose between thin core and pre-preg variants. VT-5A2 features a thermal conductivity of 2.2 W/m.K, a high Tg of 190°C, best in class thermal performance (T260 >60 Minutes, T288 >30 Minutes and T300 >15 Minutes) and M.O.T. up to 150°C. VT-5A2 is lead-free assembly compatible, fulfils RoHS and WEEE requirements and complies with UL94 V0.

The VT-5A2 thermally conductive laminate is manufactured by Ventec using strict quality controlled processes that are certified to AS9100 Revision C, ISO/TS16949 and ISO 9001:2015, and, like all Ventec products, is backed by a fully controlled and managed global supply chain, sales- and support-network.

For further information and to request a Technical Data Sheet, please contact Information about Ventec’s solutions and the company’s wide variety of products, is available at 

and/or by downloading the Ventec APP.


Si9000e is being prepared for imminent release with Support for Huray
roughness modelling.

Si9000e now supports smooth, Hammerstad (for up to 4GHz), Groisse (for up to 10GHz) and Huray models – valid up to 40-50GHz.

Revised roughness application note:

Do call your local office with any questions regarding this latest upgrade.

P.S.  If you have an active Polarcare contract and would like to upgrade – please contact

Should you wish to reinstate Polarcare, or license a new set of Si9000e please reply to me or contact your local Polar office.  Polarcare will contact youas soon as the release links become available. You will need a version 17 license to run this
