bt datasheet laminate

Hi all,

Could any one tell me how to get the detail specifications and vendor information of GTEK and BT laminates of PCB substrates ?
i would like to comapre these two laminates with FR4 to see the difference
as below :
1. Density ( g/cc ), 2. Coefficient of Thermal Expansion CTE, 3. Glass transition temperature, 4. Degradation temperature, 5. Continuous service temperature, 6. Thermal conductivity, 7. Moisture absorption, 8. Flammability ( UL-94 ), 9. Dielectric strength, 10. Dielectric constant, 11. Dissipation factor ( Loss tangent ), 12. Volume resistivity, 13. Relative cost ( relative to FR4 ).

Best Regards,
Frank

Usually datasheet It is provided on the their website
see this for FR4

& see file for BT substrate
I hope this helps

Hi Abhishekavs,
Thanks for providing the information of FR4 and BT ! In the website of Isola, i also found the data sheet of GETEK which is a registered trademark of GE Electromaterials.
Is the so called GTEK laminate just likes GETEK ? Or there is
no such so called GTEK laminate, it's just a misunderstanding ?

Hi Abhishekavs,
Thanks ! i will try to ask STACI Corporation to provide the data sheet of GTEK laminate.
