This research is focused on analysing mechanical properties of materials which can be used for lamination of multilayer PCBs with embedded components by face down technology. Mechanical properties were analysed by 3-point bend test on various types of substrate material. Materials with ...

Specimens prepared from the electrically conductive adhesive with isotropic electrical conductivity ECOSOLDER AX20 (AMEPOX) have been inspected using thermomechanical analysis (TMA), dynamic mechanical analysis (DMA), differential scanning calorimetry (DSC), thermogravimetry (TGA) and additionally also by infrared s...

When designing electronic circuits from discrete components, the finite number of component values in E series of preferred numbers is the limiting factor. For example, the E24 series contains just 24 component values per decade. If accuracy of the proposed circuit is required, use...

The development of IoT instrumentation will always be strongly influenced by the properties of the power supply system. A large number of IoT nodes creates a danger of extra expenditures when changing the battery. For this reason, the development of supply nodes tends to prefe...

In this article, the electrochemical migration of lead-free solders and electrically conductive adhesives with an Ag content of more than 70% was studied by using a water drop test in NaCl solution. The results of solder pastes were compared with the results of electrically co...

This paper demonstrates the concept of node consumption reduction for IoT applications. The main emphasis is placed on the autonomy of the whole device, which must be independent of external power supply. That is why energy harvesting based on temperature principle is used for ...

In prototyping and piece-production, stencil printing of the solder paste is expensive, and with the use of the stencil, it is not possible to react fast on changes in the design. Therefore, automatic or manual dispensers are used. This work aimed to develop a low-cost di...

A simple thermo-generator was designed using inexpensive manufacturing processes and available materials. Manufacturing processes include screen printing, vacuum deposition, surface plasma activation by dielectric barrier discharge, and modified PEDOT deposition methods. A simple and reliable DC / DC ...
