CTE coefficient of thermal

CTE = coefficient of thermal expansion. To convert kj to kcal, divide by 4.184. 

Table 10.6. Thermal properties of Si02 and some commercial glasses (Holloway 1973). TG temperature of glass transition below which the glass behaves as a rigid crystalline solid, Ts softening temperature above which the glass is soft enough to be worked or moulded, CTE coefficient of thermal expansion.

The glass transition temperature of the moulded substances must be higher than the expected operating temperatures in the electronic component. This avoids excessive shear stress between electronic component and moulded substances caused by change of the CTE (coefficient of thermal expansion) in the Tg range. The mould-release rigidity is also improved if a high Tg is obtained in the mould.
