Janne Kiilunen, Ph.D. (2014, electronics). He has worked in a number of projects relating electronics reliability and accelerated environmental testing. Janne has also been involved with project management. His specialties include accelerated reliability testing, development of testing and measurement methods, and failure analysis.


Sanna Lahokallio, Ph.D. (2017, electronics).  Sanna’s main areas have been material analysis and electrically conductive adhesives and their use at challenging environments. Her specialties include also failure analysis, reliability of RFIDs, interconnection technologies and printed circuit boards (PCB),


Juha Pippola, M.Sc. (2010, electronics). Juha’s has been working a lot with testing of industrial and power electronics devices using multi stress accelerated test methods. Additionally, Juha has been involved in projects with an aim to develop better corrosion testing methods and to analyze the effect of coatings on corrosion. His specialties include accelerated reliability testing at product level, mechanical testing, dust and corrosion testing and failure analysis.


Brief history of our background

Trelic and our expertise originates from years of research, more spesifically from Packaging and Reliability Research Group, which was established in the Institute of Electronics, Tampere University of Technology in 1998. During the years 1998-2016 the research group worked in a vast variety of industrial and academic projects. The research group always conducted a very close collaboration with many industrial companies.

The projects of the group dealt for example with miniaturization, flip chip and flex on board technologies, RFID packaging technologies, and industrial electronics packaging. Most of of the projects have included lots of material characterization and materials selections. For example, various interconnection materials such as lead free solders and electrically conductive adhesives as well as protective materials such as coatings, glob tops and over molds were widely studied in the group. The majority of the research projects dealt with reliability issues and several projects concentrated on reliability testing for example related to tailored accelerated life testing. In several projects the group developed new testing methods to assess reliability of a product. The projects were funded mostly by TEKES, but the group had also projects funded by the Academy of Finland and EU. The research foundings of the group were published in numerous scientific articles and has been presented in the leading conferences.
