Dear Technetters,We are manufactureing professional grade PCBs mainly for telecommunication equipments. We do not have facilty to measure Tg of copper clad laminates. We go by the report given by the copper clad manufacturer. 

Is it a must for PCB manufacturers to have facility for checking Tg value. Or it is enough to go by the test report of laminate manufacturers.

What is the method used to measure Tg. Is it very expensive. Are there any alternate methods to check Tg.

Thanks in advance,

Regards,
Murulidhara.S
