Project general information
Project: Components’ assembly and interconnection through combined solderless technologies – COMPACT
Finaciar support: The Executive Unit for Financing Higher Education, Research, Development and Innovation (UEFISCDI); European Commission through ERANET MANUNET programme
Project type: ERANET
Contract number: 153/2020
Period: 2020 – 2022
COMPACT project aims to develop a new manufacturing technology method to build electronic modules without using solder alloy, but materials like conductive paste or ink, resin, electroless copper. The proposed technology might allow to manufacture cheaper and more reliable electronic modules since all the problems caused by the solder joints (defects like cracking, whiskers, tombstoning, voiding, a.s.o.), and by the process (delamination, higher thermal stress of the components), will disappear.
COMPACT involves less energy Consuming processes thus contributing to the environment protection. In order to achieve its objectives, COMPACT combines two processes, the printed circuit board fabrication and the electronic components assembly, into one in which the electronic module is built layer by layer, electronic components placement and interconnection structure, by using other processes (e.g:printing, curing, encapsulation, copper deposition) with existing equipment. COMPACT allows to get robust electronic modules, fully protected to dust, chokes and humidity. It is expected that the first applications will be for harsh environments, underground (traffic/parking sensors), navy, space.

- During the research activities on the materials that could be qualified for use in the new technological method, some results were obtained that could be of wider interest. One of these was materialized in the paper “Investigations at the Interface of a Multilayer Structure Made of Non-conductive and Conductive Resins”, which was presented at The IEEE 26th International Symposium for Design and Technology in Electronic Packaging (SIITME), October 21st-24th, 2020, Pitesti. After presentation, during the discussion time interval, the presenter promoted the new technological method for electronic module manufacturing.
- Another outcome was the result of the study of electroless copper deposition on traces made by conductive paste and inks. The work “Electroless Copper Deposition on Low Temperature Silver Thick Films” was presented at the 8th International Conference on Materials Science and Technologies, RoMAT 2020, November 26-27, 2020, Bucharest.
- The problem of the current capability of conductor tracks was deepened by a new study aimed at optimizing the process of creating the tracks. The experiments, measurements and conclusions were concretized in a scientific paper “On the Increase of the Current Carrying Capability of the Conductor Tracks Made of Electrically Conductive Adhesives”. The paper was presented at the 44th International Spring Seminar on Electronics Technology, ISSE 2021, Dresden. All the authors are partners within the COMPACT Project or from a subcontractor (NANOM-MEMS).
The kick-off meeting of the project took place online on May 6, 2020. Participants:
PhD. Ana Maria Paraschiv, Gaudentiu Varzaru, Hannelore Valkanova, PhD. Rosemari Kiss, Adrian Zarnescu, Razvan Ungurelu, Ileana Damian (Syswin Solutions);

PhD.Marin Gheorghe (NANOM-MEMS).
During the Event “THE ELECTRONIC WEEK OF ELECTRONICS PACKAGING COMMUNITY 2020” which took place on-line between October 19th-24th, it was presented the paper “Investigations at the Interface of a Multilayer Structure Made of Non-conductive and Conductive Resins”. All the authors are partners within the COMPACT Project. The paper presented the results of some preliminary tests performed within the frame of the Project. The paper was presented by Gaudentiu Varzaru on October 22, during the Poster Session 1, within SIITME event.
The Event THE ELECTRONIC WEEK OF ELECTRONICS PACKAGING COMMUNITY 2020 had two distinctive sections:
The 29th Edition of Interconnection Techniques in Electronics (TIE & TIE+) and The IEEE 26th International Symposium for Design and Technology in Electronic Packaging (SIITME). The participants in the two events were both from the academia and industrial environment, being located in several parts of the world: Romania, Hungary, Germany, Bulgaria, Poland, Czech Republic, United Kingdom, Norway, Finland, Singapore, Japan, USA.
During the 8th International Conference on Materials Science and Technologies, RoMAT 2020, which was held in Bucharest, Romania, November 26 – 27, it was presented the paper “ELECTROLESS COPPER DEPOSITION ON LOW TEMPERATURE SILVER THICK FILMS”. All the authors are partners within the COMPACT Project: C. Ionescu, M. Gheorghe, G. Varzaru, M. Branzei, B. Mihailescu, S. Gheorghe, R. Ungurelu, and P.M. Svasta. The paper, which is the result of research work performed within the project, was presented on-line on November 27 by PhD. Prof. Ciprian Ionescu, Project Manager of P1 Partner – Politehnica University from Bucharest – Center for Electronic Technology and Interconnection Techniques, UPB-CETTI.
The online meeting of the project partners took place on January 15, 2021. A balance of the first stage was made and the content of the second stage was presented. Next, the mechanical and electrical testing capabilities of some structures made with polymeric materials were detailed. It was also mentioned the usefulness of performing dynamic mechanical and electrical tests on these structures.
Between May 5th to 7th , 2021, the 44th International Spring Seminar on Electronics Technology, ISSE 2021, took place in Dresden, Germany, organized by the Institute of Electronic Packaging Technology (IAVT) and the Centre for Microtechnical Manufacturing (ZmP), TU Dresden. On May 6th , during the Poster Session 1, Part B, PhD. Prof. Ciprian Ionescu, Project Manager of P1 Partner – Politehnica University from Bucharest, presented the paper “On the Increase of the Current Carrying Capability of the Conductor Tracks Made of Electrically Conductive Adhesives”.
