Microelectronic packaging

Microelectronic packaging is a major discipline within the field of electronic engineering, materials engineering and includes diverse variety of advanced technologies. It applies to the whole both process from the very beginning to the end end, products and to components. Packaging of an electronic system must consider protection from mechanical damage, cooling, radio frequency noise emission, protection from electrostatic discharge, maintenance, operator convenience, and cost. The quality of packaging control has a great influence on microelectronic products quality and competitiveness. Microelectronic packaging technology relates to many fields, from raw material to process, from inorganic to polymer, from large-scale production equipment to computational mechanics. Nowadays, microelectronic packaging has become a key industry to our modern information society.



CEMAR microelectronic packaging laboratory has accumulated abundant experiences in the area of microelectronic packaging with which we successfully solve problems from mechanics, materials science, and the production process.
