Cte curve of silicon
WebDisplayed in Figure 3 are the CTE values measured on an epoxy printed circuit board below and above Tg. Figure 3. TMA results on epoxy PCB showing assessment of coefficients of thermal expansion Below Tg, the printed circuit board has a CTE value of 50.5 µm/m°C, while above Tg, the value of the CTE increases to 270.7 µm/m°C. Webcurves were generated for pressures based on the liquid and the elastomer equations above assuming a Poisson’s Ratio of 0.49 and a volumetric CTE of 0.001 and shown with the …
