WebDynamic mechanical analysis (DMA) is widely used to explore the viscoelastic properties of polymers that occur as a response to the application of oscillating forces and make conclusions about mobility of polymer chains and the deterioration of polymers’ thermomechanical properties due to hygrothermal ageing effects [6,7]. WebOct 1, 2024 · Thermomechanical Analysis is applied according to IPC standard to test for material suitability. The new TMA 402 F3 Hyperion® Polymer Edition is specifically designed to measure a wide range of polymer materials and is well suited for the quality control needs of the electronic component industry.
Dynamic mechanical analysis (abbreviated DMA) is a technique used to study and characterize materials. It is most useful for studying the viscoelastic behavior of polymers. A sinusoidal stress is applied and the strain in the material is measured, allowing one to determine the complex modulus. The temperature of the sample or the frequency of the stress are often varied, leading to variations in the complex modulus; this approach can be used to locate the glass transition temp… WebDMA systems detect dimensional changes with hypersensitive optical sensors, and track damping through the applied force probe. These two metrics, recorded as a function of …
