    An overview is given of stress-free potting. The coefficient of thermal expansion (CTE) and melting point of component materials are related because of the strong correlation between the two properties. Equations given are tools that can be used by the formulator to help bring the formulated product to the desired CTE and melting point. Shrinkage, a direct result of covalent bonding during cure, i... View full abstract»
