Webtangent line to the curve above and below the transition in the curve. The temperature where these tangents intersect is the TMA determined T g for the material. If the tangent method fails to provide an adequate T g, the instantaneous CTE can be calculated (see 5.4.3) and the midpoint of the step change in CTE may be taken as T g (see Figure 3 ... WebThe CTE curves for different silicon concentrations show almost the same gradient. Consequently, the CTE can definitely be adjusted to electroless nickel with a certain phosphorous content in a ...
