The IMAPS is a non-profit making organization whose aim is to spread knowledge relating to hybrid microelectronics; a key technology in the assembly and application of semiconductors, thin film circuits and printed circuit boards (PCBs) to form practical miniaturized electronic equipment. In 2008, the IMAPS joined with the IEEE Components, Packaging and Manufacturing Technology (CPMT) Society, bringing into formation the IMAPS-CPMT organization. In this special issue of Microelectronics International, ten papers have been collected, covering the processes and procedures associated with LTCC technology, photovoltaics and LED issues.
