Thermal imaging cameras are useful for optimizing the layout of electronic components by allowing engineers to visualize temperature distributions and heat development over time without contact. High-resolution cameras are needed to measure the smallest structures reliably. The Testo 890 camera meets these needs with a 640x480 pixel detector and 42° lens, enabling resolution of structures as small as 113 micrometers. This allows engineers to record thermal processes in real time via fully radiometric video and analyze temperature measurements at any point to precisely study heat development and identify areas for improvement.

Thermography in
microelectronics
Precisely visualising critical temperatures.
Electronic components are becoming smaller and
smaller, the demands on heat withdrawal are
increasing. For optimisation purposes, an examination
of temperature conditions using a thermal imager is
expedient, and the analysis of warming and cooling
behaviour over defined time intervals is often required.
Only high-quality thermal imagers with the highest
geometric resolution and the possiblity of recording
fully radiometric video sequences are up to this job.

The application
Heat development on a test bench.
The miniaturisation trend in electronic components continues – and
with it, the requirements regarding heat transfer: even the smallest
components in the narrowest spaces create heat which can affect the
component itself or adjacent assemblies. Especially the development
of heat over time can negatively influence the functionality and life
expectancy of an instrument.
Thermography is an effective tool for the optimum dimensioning and
positioning of electronic components for an ideal circuit board layout:
It allows temperature distribution and development to be identified
without contact even in the smallest scales. Since thermal curves
frequently also need to be taken into consideration, individual thermal
images are often not sufficient.
The solution
Visualize heat development in detail –
without contact.
Thermography of microelectronics requires a very good geometric components: You record thermal processes in real time with the fully
