Learning outcomes
The main scope of this study is to introduce actual technology and possibilities of how to design modern electronic devices. In this subject students will be informed about techniques and manufacturing processes of printed circuit boards (PCB), as well as assembly technology. Students will be informed about computer aided design systems and how they work. Primary task will be how to design printed circuit boards using design rules to perform product needs and electromagnetic compatibility requirements.
Students get knowledge about printed circuit boards. Especially how they are designed and manufactured including assembling technology of complex electronic devices. They will be informed about trends in CAD, CAM systems for electronics design & manufacturing process.
Prerequisites
Basic PC skills, basic knowledge of electronics, physics, material technology.
