Assessment on using Solderless Assembly for Electronics in Space Applications, authors: Ciprian Ionescu, Gaudenţiu Vărzaru, Mihai Branzei, Norocel-Dragoş Codreanu, Ioan Plotog, Paul Svasta.

The paper presents the results of our investigation in implementing a solderless assembly process for electronics. The addressed technology is known as the Occam process and was patented by Verdant Industries. It is presented our proof of feasibility, at least for a prototyping phase on a single connection layer. Different from the original process that... Read More

A cost-effective solution for remote Carbon Dioxide indoor monitoring, authors: Gaudentiu Varzaru, Adrian Zarnescu, Razvan Ungurelu, Andra Gabriela Iordache

As the forth atmospheric gas in order of concentration, CO 2 is proven to affect health and productivity, thus monitoring its presence in offices, schools and industrial buildings has become a good practice The present work was generated by a real estate company request for designing and manufacturing of an in door CO 2 monitoring...

Integrating Soil pH Measurement Into An Internet Of Things Application, authors: Adrian ZĂRNESCU, Răzvan UNGURELU, Marius – Ionuţ MACOVEI, Gaudenţiu VĂRZARU.

Soil pH is an indicator of the soil quality because it affects plant growing The work presents a device for soil pH determination on site and remote transmission of the result. Normally soil samples are taken from the field and tested in door in aqueous solutions using However, it was an increasing demand for on... Read More

Considerations regarding Computer Aided Design of a structure to be manufactured in Occam technology, authors: Victoria Soare, Gaudentiu Varzaru, Adrian Zarnescu, Razvan Ungurelu, Ciprian Ionescu.

Occam technology comes with significant changes in the way the electronic modules are made because two processes, the fabrication of the printed circuit board and the assembly of the electronic module, are replaced by a single one A compact structure containing the components and the interconnection layers are created one by one on a single...
