The Features of the EM-370(5) Laminate
High Decomposition temperature
The decomposition temperature (Td) refers to the temperature at which a PCB material decomposes chemically. EM-370(5) has a high decomposition temperature. The Td is 385 degree Celsius.
Mid-Tg value
The glass transition temperature describes how a PCB material transforms from a solid state to a molten state. EM-370(5) features a glass transition temperature of 150 degree Celsius. Therefore, this PCB material will be unstable once it works beyond 150 degrees Celsius. This Tg value helps to determine the limit of temperature operation.
Lead-free compatible FR-4.0
