Isola Analytical Services Laboratory is home to the largest collection of Thermal Analysis equipment in North America.  DSC, TGA, TMA and DMA instruments are available to provide a full range of thermal data on prepregs, laminates and printed wiring boards.

Differential Scanning Calorimetery, also called DSC measures the flow of heat into or out of a sample compared to a referenced.  Changes in the heat flow indicate glass transition temperature and reactions such as curing and melting of material.

TGA, Thermogravimetric Analysis, utilizes a microbalance to measure finite changes in weight as a sample is heated at a controlled rate.  IPC-TM-650 defines decomposition temperatures as 2% and 5% loss of the initial weight while the sample is heated at 10C/min or held isothermally at a desired temperature over time.  Presence of moisture can also be measured.

Thermomechanical Analysis, or TMA, measures the change in the height of a sample as it undergoes a change in temperature.  Changes in the sample height are utilized to determine the coefficient of thermal expansion, the glass transition temperature and time to delamination at a temperature of interest.

DMA, Dynamic Mechanical Analysis measures the change in the stiffness of material as it is heated at a controlled rate.  Changes in the stiffness are used to determine the glass transition temperature of a material.

Each piece of Thermal Analysis equipment measures a different characteristic of a material.  Isola Analytical Services Laboratory offers full testing of all thermal properties by DSC, TGA, TMA and DMA.
