Micro Nano Lab (MINOLab)

MINOLab’s mission is to setup, maintain and develop applied and innovative research, testing, analysis, design and prototyping for printed circuit boards (PCBs), micro- and nanoelectronics with an accent on electromagnetic compatibility, RFID, MEMS, and biomedical applications.

The goal is to solve problems originating from real world applications in electronics, microelectronics and nanoelectronics, development hi-tech as well as affordable methods and tools for design, modelling and testing.

At MINOLab we deliver services for root cause analysis of failures and defects in electronic devices. We also provide research and development (R&D) and optimization of novel devices, products and systems.

Main activities:

  • Early detection and analysis of failures in micro- and nanoelements, devices, modules, systems, prototypes
  • Measurements and characterization of integrated circuits and systems, PCBs and devices
  • Design at circuit and component level, prototyping
  • Development and testing of devices at circuit and system level including embedded systems
  • Training in electrical engineering, micro- and nanoelectronics for company employees, students, experts, etc.
  • MINOLab partners in 2 ongoing projects for grants BG16RFOP002-1.005 “Development of product and manufacturing innovations” of Operational Programme “Innovation and Competitiveness” 2014-2020
  • MINOLab partners in a project for setting up a network in robotics through Digital Innovation Hubs (DIHs), Grant Agreement № 824964 “DIH2 – A Network of Robotics DIHs for Agile Production” по процедура H2020-DT-2018-2020/H2020-DT-2018-1. Leading partner is VTT Technical Research Centre of Finland Ltd.
  • Extensive cooperation with the Technology Transfer Unit within the EU Joint Research Centre (JRC)
  • Cooperation with the companies from the Cluster of Microelectronics and Industrial Electronics Systems and companies from the industries of microelectronics, nanoelectronics, industrial electronics, automotive, etc.
  • Collaboration with the Technical University of Sofia with regards to diploma projects and theses, PhD dissertations, and R&D projects
  • Cooperation with the Technology High School of Electronics Systems
  • Collaboration initiatives pursuant to the MoU with IMEC Academy (Belgium) with the support of Sofia Tech Park AD.
