Specific course objectives

The Electronic materials and technologies course provides basic knowledge on production technology of passive electronic components, technology interconnect (printed circuit boards, hybrid circuits) and silicon-based monolithic integrated circuits technologies.
The aim of the curse is to guide the student to think in terms of technological feasibility.
The course is directed to students who will work in design, production, application and management of products and electronic systems.

Course programme

In the first part the course provides an introduction to key technologies for manufacturing integrated circuits and individual technological steps associated with them.
The second part of the course provides an overview of key technologies and materials used in the manufacture and assembly of electronic components and systems.

Introduction to silicon monolithic integrated circuit technology

• Integrated circuits

Printed circuit technologies

• Materials for printed circuits.
• Technological steps for the realization of printed circuit boards.
• Production processes:
  - single-sided PCB
  - double sided and multilayer.
• Assembly:

Testing and exams

The exams cosist in written and oral tests. Final mark is determined 1/3 by the written test and 2/3 by the oral test. Two ongoing tests will be carried out during the course: the candidates that successfully pass these tests will not be required to carry out the written test.
