Quality assurance in microelectronics with thermal imagers from Testo.

Precisely visualizing critical temperatures.

Electronic components are becoming smaller and smaller, the demands on heat withdrawal are increasing. For optimization 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 possibility of recording fully radiometric video sequences are up to this job.

The challenge.

The miniaturization 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.

Thermography of microelectronics requires a very good geometric resolution in order to be able to measure the smallest structures reliably. A detector size of 640 x 480 pixels is often indispensable here. In the thermalimager testo 890, the intelligent interaction of the system components with a 640 x 480-pixel detector and a 42° lens allows a focus distance of only 10 cm. This enables the resolution of tiny structures of 113 μm. The testo 890 offers all preconditions for the thermography of electronic components: You record thermal processes in real time with the fully radiometric video measurement, and transfer the data directly to a PC. The recording can be stopped and analyzed at any point. And: For every instant in the video, all temperature measurement points are exactly available per pixel, so that you can precisely analyze all thermal developments and if necessary introduce optimization measures.

Testo thermal imagers offer best image quality and sharp system mechanism. In order to be able to conduct thermography applications with the highest possible level of security and effectiveness, the engineers at Testo have not only developed innovative technologies, but have also adapted them to each other preferably in the thermal imagers. This means that each Testo thermal imager is an instinctively operable, highly developed thermography system.
