COMPACT is the Interreg Nord, European Regional Development Fund (ERDF) project that works from the premise that an honest research can generate new job opportunities. It is well known that up-north of Sweden and Finland are always remained in isolation mainly due to low population density and cold-weather influenced living environment. Most important this area has low economic growth compared to the southern part of the countries. Thus, it becomes essential in this region to induce the growth through collaboration like development of new competence for the regional business community. High Density Interconnects (HDI) PCBs manufacturing market is expected to grow from USD 9.5 billion in 2018 to USD 16.9 billion by 2023, at a CAGR of 12.3% from 2018 to 2023. Thus, it can be seen that HDI-PCBs soon be applied to nearly every electronics gadget that is under the use. Presently, few major players from EU, USA and China has this capability to manufacture HDI-PCBs.


The project COMPACT is an attempt to bring-up a high desity PCB manufacturing methodology to SMEs present in the northern region to compete with the well established industries in the field. COMPACT tends to set a platform for economical upgrading of the SMEs using the research conducted by the domain experts of the northern universities of both Sweden and Finland.

Our Approach

The project constitutes of three stages. First, design and development of interconnects using the SBU technology based on Covalent Bonding Metallization (CBM). The next stage is to perform the reliability analysis of developed structures. Finally, standardization of the process for commercial purposes using the design and analysis data.Thus, this research, design, fabricates and evaluates methods and tools will support the northern SME in creating their presence on globe in HDI- manufacturing facilities


The focus of this work is to develop a cost-efficient, flexible and reliable fabrication methodology that will be suitable for bulk production pf PCBs. The work is planned to be done using Sequential Build Up (SBU) process where the methodology used is fully additive and feasible at room temperature.

Our Mission

Few of the outcomes of the project would be greatly miniaturized electronics devices with new manufacturing technology, Reduced manufacturing time and costs with completive products , Improved and managed reliable devices for customers, More environmental friendly manufacturing due to the lower amount of chemicals and easier waste management , Growth of the regional industry according to Industry 4.0 norms, New scientific results and practical outcomes for all partners and general audience and many more.

Funding Agency

The EU program Interreg Nord supports cross-border cooperation with the intention of strengthening economic and social development during the period 2014-2020. The overall goal of the Nordprogramme is to strengthen the program area's competitiveness and attractiveness. The program includes northern Sweden, northern Finland, northern Norway and Sápmi. The region differs from other European areas by its Arctic features with cold climates, polar nights, large natural areas and abundant natural resources.

The overall goal of Interreg Nord 2014-2020 is to strengthen the competitiveness and attractiveness of the programme area. To achieve the overall goal, the region’s development needs to take place in an economically, socially and environmentally sustainable manner. This is achieving this through funding the cross-border cooperation that will address the common challenges identified in the border regions and make use of under-utilised opportunities in the border areas. At the same time, the collaborative process needs to be strengthened which will generally foster harmonious development within the EU and its neighboring countries. Thus, the Interreg Nord is working continuously in building common conditions for the northern region of Sweden, Finland and Norway to further develop a resource-efficient, environmentally friendly, competitive and low-carbon society

The Regional Council of Lapland is a statutory joint municipal authority, the members of which are all of the 21 municipalities of Lapland. The council’s work centres on the wellbeing of Lapland’s people, as well as the living force, pulling force and holding force of Lapland. This is achieving via the vision of “We are an inspired, “consider it done” team that gives a positive boost to Lapland. We promote the success of Lapland and the wellbeing of the people of Lapland”. The core tasks of the Regional Council of Lapland are the strategic development of the region, planning and safeguarding the interests of Lapland at both the national and international level. In order to ensure the success of Lapland’s people, businesses and other stakeholders, we carry out broad representation of interests and lobbying in Finland, in the European Union and in other international cooperation forums.

The northern most university of world was founded on 1 June 1971 at Porsön in Luleå as Högskoleenheten i Luleå. The name was later changed to Högskolan i Luleå (Luleå University College). In 1997, it was granted university status by the Swedish government, and is since known as Luleå University of Technology. We offer world-leading competence in several areas of research. The research activities are conducted in close collaboration with industries such as Bosch, Ericsson, Scania, LKAB, SKF and leading international universities. The Electronic Production subject of EISLAB LTU works on the development of miniaturized PCBs developments using sequential build up, SBU, approach. Here chip and passive components, connectors and power supply will be connected by through electroless copper processes. This process will be a major advancement of the current embedded chip technologies. Thus we are foreseeing the replacement of technologies like bonding, chip encapsulation, and soldering with an embedded component approach based on SBU technology.

The University of Oulu is an international science university which creates innovation for the future, well-being, and knowledge through research and education. Founded in 1958, our community is 13 000 students and 2900 employees strong, and one of the biggest and the most multidisciplinary universities in Finland. The university consists of eight faculties and many specialized research units. Microelectronics Research Unit (MIC) is part of the Faculty of Information Technology and Electrical Engineering. MIC's research is focused electronics materials and their applications, and it also provides education to Electrical Engineering Degree Programme with various courses and thesis in Bachelor and Master levels. MIC is known in its long-term and advanced research on electronics reliability. The team’s main scope is in improving reliability of electronics by monitoring methods by observing the degradation of electronics interconnections while simultaneously characterizing accelerated testing-induced changes in test structures by means of various characterization methods. To improve the accuracy of lifetime prediction of interconnections, different models are used. The team is fully equipped to perform the testing including thermal cycling, humidity testing, and all needed inspection methods.
