There are many methods used for quality investigation and for optimizing production processes. Such optimization methods help with increasing production effectiveness, decreasing costs and increasing the quality of products. In this paper, fractional factorial experiments are applied to investigate different factors of electrically conductive adhesives modified with silver nanoparticles after the application of mechanical aging and the influence on resistance and non-linearity of joints. The factors considered in the experiment were concentration of silver particles, the size of nanoparticles and the combination of both factors.

SU-8 is widely used as a material for sensors and actuators or as a bonding layer for microelectromechanical systems (MEMS). Therefore, its physical properties, such as the Young's modulus and the thermal expansion coefficient were broadly investigated. However, no reliable data can be found around 0°C. Therefore, the thermal expansion of the material in the temperature range of -30°C up to +30°C was examined. The thermal expansion was measured via the deflection of appropriate designed structures with the help of an optical microscope. A sealable chamber with a Peltier-element was built and utilized to control the temperature and the ambient atmosphere (N2). It was found, that SU-8 shrinks, when absorbed water vanishes due to an N2 purge. Additionally, the thermal expansion of the SU-8 exhibits a non linear behavior in the range from -20°C to +20°C.

This article deals with the research of singlet oxygen generation using phthalocyanine photosensitizer. Singlet oxygen is extraordinary reactive and can be used in many applications such as photodynamic therapy, disinfection or chemical synthesis. For singlet oxygen generation, the photosensitized method in a new developed generator based on LED emitters was used. The amount of singlet oxygen generated by LED emitters was compared with laser excitation. The principle of measurement, design of a singlet oxygen generator and control unit are discussed in more detail.

In the previous work we have been engaged in experiments of the solder paste consisting of nanoparticles of silver with different grain sizes, and also carbon nanotubes (CNT) before and after modification. The basic properties of the tested pastes were very promising. Here we would like to present our findings on mixed solder pastes that consist of silver nanopowder and modified CNT. Such mixtures have not been presented in the literature yet. In this article the results of basic tests such as slump, solder ball etc. as well as results of shear tests of solder joints will be presented.

The paper focuses on various technological possibilities of production that are used in the branch of UWB filters. This paper demonstrates the design of LP filter realised by the Filter Solution 2011 from Nuhertz as well its simulation done by Ansoft Designer from ANSYS. Simulated and measured results of insertion loss and return loss response of LP filter for UWB radar are presented. This paper assesses the suitability of hydrocarbon ceramic laminate substrate for the production of LP filter for high frequency (HF) area. Paper refers to the needs to be focused on the design of passive filters used in UWB radar systems with emphasis on issues of quality of transmitted signals in the HF range. It examines potential manufacturing possibility of such filter based on Low Temperature Ceramics (LTCC) technology too. The presented filter is an example of an antialiasing LP filter for particular laboratory UWB radar.

This paper examines a new technology to overcome the warpage of thin dies during electronics assembly. A liquid is encased in the gap between substrate and die, which acts as capillary. Consequently the die is planarized due to capillary pressure caused by the capillary action in the gap. Influencing factors on this effect, like gap height, level and orientation of die warpage, volume of liquid and the kind of the used liquid, were investigated. It was found that the success of the planarization depends strongly on the warpage orientation of the die. In case of a concave warpage orientation the technology is sensitive on the volume of the liquid, the gap height and of the warpage level in the initial state. In contrast, the planarization works significantly better for a convex warpage orientation and is less sensitive to parameter changes. The reasons for these differences were explained by a mechanical beam model.

In this work investigations are connected with development of method of LEDs' junctions' temperatures estimation at real operating conditions. Direct junction temperature determination is not possible and alternative methods have to be developed. Suitable, cheap and reliable method for direct estimation of LEDs' junction temperatures during operating of lighting equipment is proposed. It is realized by employing the temperature dependence of LEDs' forward voltage drop. Two different types of LEDs have been investigated at various ambient conditions (air temperatures from 20°C to 45°C) and different current values through LEDs - from 350 mA to 600 mA. Recommendations concerning calibrations, calculations and junctions' temperatures evaluations are presented. Developed method allows achieving of reliable results “in situ” for thermal performance of LEDs using non expensive experimental equipment.
