Micro-Thermography Opens Up New Possibilities for Quality Control and Development

Micro-thermography with detailed image

Complex electronics are becoming more powerful and smaller, so that in their development, thermal management is becoming increasingly important. The placement of electronic components on printed circuit boards is done in a small space, so good heat dissipation is necessary. Microt-hermography allows for the thermal analysis of extremely small structures in the micrometer range, providing a detailed representation of the temperature distribution on complex electronic assemblies and components.

The thermal imaging camera series VarioCAM® High Definition and ImageIR® by InfraTec can be equipped with microscope objectives of different magnification factors.

Using the 8x microscope of ImageIR®, for example, high-resolution detail shots of eletronic assemblies and components can be produced with a pixel size of up to 2 µm. By using the opto-mechanical real-time MicroScan unit of the infrared camera series VarioCAM® High Definition, which is designed for continuous operation, up to (2,048 x 1,536) IR pixels can be achieved. At this resolution, even the smallest defects in measurement areas can still be reliably detected.

Thermography on the Trail of the Fault

Today, thermographic damage and function analysis of electronic components is an established test method in electrical engineering. This method is also used for research purposes at the Institute for Electrical Systems and Energy Logistics at BTU Cottbus-Senftenberg. In this context, Prof. Dr. Ralph Schacht is intensively involved with the material and system characterisation as well as the non-destructive failure analysis of printed circuit boards, electronic components, microelectronics as well as composite systems of packaging and interconnection technology.

Thermal Micro Actuators for Nanotechnologies

Microelectromechanical systems (MEMS) offer a wide range of possible applications in the field of nanotechnology. Everyday examples are the position recognition of mobile phones and the use in airbags, digital cameras or pacemakers. Other applications can be found above all in the field of miniaturised medical diagnostics. Growing demands on miniaturisation affect both the system solutions required for this and the sensors and control elements to be developed.

At the same time that the performance of electronic components is being driven ever higher the demand for thermal management at ever smaller scales is also occurring.

How do solid materials change structurally? The engineers Prof. Stefan Seelecke and Marvin Schmidt from Saarland University investigate this fundamental question in materials research. Both consider this topic with the help of microthermography. Their cutting-edge basic research ensures that we will have even more energy-efficient electric devices to use at home in future.

    MicroScan – Quadrupling the Number of Pixels

    Displaying measurement objects with extremely low noise and fine resolution – this is what MicroScan is for. Using this function, the native pixel number of the detector can be quadrupled. This results in thermograms of better image quality with geometric resolutions of more than 5.2 Megapixels. Each pixel in the image represents a true temperature reading, not an interpolated pixel.

    10 GigE Interface for a Strong Increase in Output

    The 10 Gigabit Ethernet interface of the high-end camera series ImageIR® opens this extremely fast transmission standard with a NIC specially developed by InfraTec. This works with optical or electrical transceiver modules that are easy to change and are called SFP+.

    Different 10 GigE fiber SFP+ transceivers allow transmission ranges of up to ten kilometers with the same low sensitivity to electromagnetic interference. A corresponding standard SFP ensures backward compatibility with the conventional GigE interface. This combination allows the ease of use of the cameras with the 10 Gigabit Ethernet interface in existing systems - though at a reduced transmission rate.

Accurate Readings through Special Software

Operational concept thermographic software IRBIS 3

In contact-less temperature measurement, using infrared thermography in electronic assemblies, it should be noted that objects often have different emission behavior. For example, ceramics and plastics have a relatively high emissivity, while copper conductors and leads are very low. 

When using the correction models for automatic pixel-wise adjustment of the emissivity, as contained in the thermography software IRBIS® 3 from InfraTec, measurement errors can be avoided effectively. This function is performed after recording the emissivity distribution of a uniformly-heated test specimen. In the subsequent thermographic images, a precise correction of the emission levels takes place, thus giving a correct determination of the temperature of each individual object.
