So lets assume a PCB is made out of FR4 which has a CTE of 17 (usually it is 14 to 17 ppm/°C). 2010-09-22 · The expansion is expressed in parts per million per degree Celsius (ppm/°C). A PCB will expand in length or width by 14 parts per million per Celsius degree. 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.

Excerpt from Sep 22, 2010 A typical FR-4 laminate has a CTE of 14 to 17 ppm/°C. This is fine, until we consider that the large silicon chip packages we solder onto a PCB List of Thermal Expansion Coefficients (CTE) for Natural and Engineered Materials Cadmium Selenide, CdSe (Sputtering Target), Parallel to a-6.26, c- 4.28.

The designations for CE alloys are constructed using the following model: CE stands for Controlled Expansion. The number following after 'CE' (e.g. 7 in CE7) gives the room temperature CTE in ppm/°C.

Selecting an adhesive with a low coefficient of thermal expansion (CTE) is one of the approaches to improve the bond strength and stability between dissimilar substrates. Low CTE adhesives mitigate the mismatch in thermal expansion between the substrates being bonded, as well as between the CTE is usually given in units of um/m/°C or ppm/°C.

To put this in perspective, imagine if 1 m 3 blocks of stainless steel, borosilicate glass and quartz ware were placed in a furnace and heated by 500 °C. As expected, the CTE results show a slight temperature dependence. From the data in Table 9, an overall average value for the CTE of Sn3.5Ag is about 21.5 ppm/°C. For comparison purposes, a value that is often quoted for the CTE of eutectic SnPb is 24 ppm/°C.

Sources: www.owlnet.rice.edu/~msci301/ThermalExpansion.pdf 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). Epoxy resins have CTE’s around 50 ppm/°C below the Tg. If the system has filler in it, the CTE can be lower due to the very low expansion of the filler component.
