### Coefficient of Thermal Expansion - an overview ...

Coefficient of Thermal Expansion: The CTE differs greatly between metals and plastics, that is, the two materials expand and contract by different amounts. Expansion/contraction of plastics is generally greater than that of a metal. Hence, areas of high stress are created around the molded-in inserts. To overcome early failure, thicker boss walls are used to compensate for these high stresses ...

Coefficient of thermal expansion is defined as the change in unit length per degree of temperature change. In a concrete element, it is therefore a measure of the free strain produced in concrete subject to a unit change in temperature and is usually expressed in microstrain per degree centigrade (με/°C).It is a very important property of concrete which influences its behaviour under ...

The Coefficient of Thermal Expansion is the rate change in the size of an object (could be solid, liquid or in gaseous state) with the rate change in the temperature. It generally measures the fractional change in the size of the object with the change in the temperature keeping the pressure constant. There are several types of thermal coefficients that are developed such as linear, volumetric ...

### What is the Coefficient of Thermal Expansion …

The Coefficient of Thermal Expansion (CTE) specifies how much a printed circuit board will expand/contract when it is heated or cooled. The unit of CTE is PPM/°C i.e parts per million per Celsius degree. So lets assume a PCB is made out of FR4 which has a CTE of 17 (usually it is 14 to 17 ppm/°C). If the PCB is 1 Million inches long then it will expand by 17 inches for every 1 °C increase ...
