What is thermal conductivity testing?
Thermal conductivity testing is a process of making the element/product exhibit properties of transferring heat through its body, products that are able to transfer heat quickly through them are called good conductors of heat and the ones that are not able to pass heat through their bodies are called poor conductors of heat.
Thermal conductivity testing is necessary for measuring the heat receptivity of appliances to ascertain the range of heat insulation, conduction, and transfer abilities acquired by the product. This thermal conductivity is comprised of several factors such as the material, density of the product, and other factors such as pressure, temperature, etc.
These tests can help in minimizing chances of shocks, current leakages, and short circuits that can sometimes become lethal to the consumer's well-being, standardisations are also provided by International organizations such as the ISO that require mandatory testing for shock resistance. The inability of the following can cause companies in huge numbers and can even lead to license cancellations, hence pre-release thermal conductivity testing is mandatory in today's environment for any of the specified products.
Accurate knowledge of a material's thermal conductivity aides in making predictions on the capacity of heat transfer by conduction. Thermal conductivity is a pure material property independent of conduction-area or material thickness. ASTM D5470 is a standardized two-sided, one-dimensional heat flow approach that is increasingly been used for thermal conductivity measurement in a wide range of devices. The most popular units for thermal conductivity are Watt/meter Kelvin (W/mK). Thermal resistivity is simply defined as the reciprocal of thermal conductivity.
The most pertinent reason for thermal conductivity testing lies in the potential of damage due to overheating or bad conductivity through an element that can cost heavily to both the producer and their final consumers since thermal conductivity is a material property that is independent of any particular application since material properties are ideally "application-independent".
There are critical aspects of understanding the nuances related to factors that determine the conductivity of other elements in the compound hence there is a need for evaluating the overall thermal performance of any particular electronic device, therefore Semiconductor Thermal Testing is conducted to determine the overall thermal resistance of a packaged semiconductor device.
