The average CTE value for quartz glass at about 5.0 × 10 -7 / °C is many times lower than that of other common materials. 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.

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. The CTE employs reciprocal temperature units (K -1 , °F -1 , °C -1 , etc.) representing the length change per degree per unit length, e.g., in./in./°F or mm/mm/°C.

Novastrat® 800 has been successfully used in applications requiring the stability of low CTE from cryogenic conditions In solder joining, unlike brazing (over 450C) the component parts require heating to ~ 250 °C. Looking at the CTE values in the table below, a 12” plate of Aluminum will grow by almost 0.060” while the 12” plate of aluminum oxide will only grow by about 1/10 that amount with a CTE of 4.4 ppm for Alumina vs. the 23 ppm for Aluminum.

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).

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.

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. Hence, thermomechanical analysis grows in importance.
