property of interest is the coefficient of thermal expansion (CTE). Package reliability concerns require that differences in the CTE among the materials in the package be understood and managed. Semiconductors have relatively low expansion coefficients (Si ~ 2.8 ppm/°C and GaAs ~ 6 ppm/°C at room temperature). This CTE can be reduced through the use of ceramic or specialty negative coefficient of thermal expansion fillers, to values as low as 10 ppm/C at room temperature. It should be noted that adding such fillers in adhesives increases the modulus significantly. Linear Coefficient of Thermal Expansion Values of Several Plastics The Coefficient of Linear Thermal Expansion (Or Linear Coefficient of Thermal Expansion) lies between (in the service temperature range for each case): Ca. 0.6 x 10-4 to 2.3 x 10-4 K-1 for most of the thermoplastics; Ca. 0.2 x 10-4 to 0.6 x 10-4 K-1 for thermosets The linear thermal expansion coefficient (CTE) is dependent on the material from which an object is made. Generally, linear thermal expansion is most applicable to solids.

This means that if a PCB were 1 million inches long, it would expand by 14 inches for every Celsius degree of temperature increase. A typical FR-4 laminate has a CTE of 14 to 17 ppm/°C.

CTE simply means that every material in the world expands or contracts as its temperature changes. The expansion is expressed in ppm/°C or parts per million per °C. For example, Fr4 typically has a CTE of 22 ppm/°c or 0.000022 inches expansion per °C.

If a material is flexible, such as a silicone or a flexible epoxy, the CTE can be above 200 ppm/°C. The coefficient of thermal expansion for a material is usually specified over a temperature range because it varies depending on the temperatures. The following values are given for a temperature around 20 °C. CTE is usually given in units of um/m/°C or ppm/°C. The expansion is expressed in parts per million per degree Celsius (ppm/°C).
