PCB Thermo-mechanical Properties of Base Material
The two main properties of PCB base material are thermo-mechanical and electrical. PCB Thermo-mechanical Properties of Base Material: PCB Thermo-mechanical Properties: Thermal expansion can be calculated by thermo-mechanical analysis (TMA). This method uses a device which measures dimension of temperature versus sample. The z-axis CTE or x/y CTE can be measured depending on the orientation of sample in device. CTE means Coefficient of
