Above and below the glass transition the coefficient of thermal expansion should increase continuously with temperature (37).
From such a curve, one can obtain the coefficient of thermal expansion (CTE) and determine the glass-transition temperature.
The coefficient of thermal expansion of the composite was measured by using a bar-shaped specimen in the linear dilatometer (manufactured by ANTER Co.
1, it is clear that a temperature difference of only about 167[degrees]C to 222[degrees]C (300[degrees]F to 400[degrees]F) is all that is needed to have the screw lock up in the barrel if the coefficient of thermal expansion is in the range of 1OE-6 to 17E-6/[degrees]C (6E-6 to 10E-6/[degreesF).
Orthotropic material was assumed, and the Young's modulus, the Poisson's ratio, and the coefficient of thermal expansion were calculated.
The resulting substrate has a coefficient of thermal expansion (CTE) that is nearly identical to GaN yet offers an industry standard sapphire growth surface (available in both c- and r-plane sapphire orientations) suitable for MOCVD and HVPE growth environments.
The component offers very low loss -- and matches the coefficient of thermal expansion (CTE) of typical power amplifier PCBs like, FR4, G-10, Rogers 4003/4350, and Taconic RF-35 substrates, for increased durability in the field.
Other benefits are said to be reduced coefficient of thermal expansion and an improved hermeticity (i.
Three formulas are available, including ALRAM 100 and ALRAM 200, which both are high-purity alumina for chemistry control, neutral to acidic chemistry and have controlled expansion properties, and MACRAM 100, a temperature product with basic (alkaline) chemistry and a high coefficient of thermal expansion.
At this temperature, the slope of the curve decreases significantly, indicating a large increase in the coefficient of thermal expansion.
Excessive stresses during thermal cycling can arise from a mismatch in the coefficient of thermal expansion (CTE) between the package materials, potentially causing catastrophic device failure.
It also boasts low coefficient of thermal expansion, high compressive strength, and good wear resistance.
They also possess a low coefficient of thermal expansion and are offered in an intermediate and low-density product line.
Supplying superior thermal dissipation, the new packages provide manufacturers of electronic devices, such as graphics processors, transportation power modules, and military communication components, with dramatic device power and reliability improvements through extremely high thermal conductivity (1,200 W/m-K) paths and a tailored, low coefficient of thermal expansion (CTE).
But because they are brittle, they are not good for parts requiring flexibility because of their end use or the difference in the coefficient of thermal expansion (CTE) of the two substrates, which can result in warping.
