The use of infrared thermography in electronics and electrical industry allows contactless measurement of surface temperatures with an infrared camera without contacting temperature sensors. It is an elegant, non-invasive optical temperature measurement method for simultaneous and temporally high-resolution detection of a number of measurement points.
Infrared Camera Enables Contactless Measurement in Electronics
The thermographic inspection of electronic components and assemblies is an established test procedure for failure detection and quality management – from the development of first prototypes to serial production. This enables, for example, the following to be detected:
- Hotspots and atypical temperature distributions on the surface of printed circuit boards, integrated circuits and multichip modules
- Increased contact resistances
- Increased resistance due to constriction of wires
- Hidden cracks in joints
- Power losses due to RF mismatch
- Incorrect thermal connections of heat sinks
- Short circuits, soldering defects such as cold solder joints
Thermographic analysis during each development step provides important conclusions for the optimisation of heat management and the design of complex electronic assemblies. In electronics production thermographic temperature measurement is used as a versatile instrument for quality assurance. High-performance thermography has become indispensable for setting critical technological parameters and their permanent monitoring as well as for inline testing of products in the production process and their final functional test.
