The cost of packaging in micro electronics is around 30% of total production costs, but this is rising at an alarming rate due to
the increasing consumer demand for smaller and smarter portable electronic devices. In micro systems, the costs of
packaging can be up to 80% of total production costs. Technological advances to reduce packaging costs are therefore of
pivotal importance to maintain the competitive edge of assembly companies. Moreover, with the exodus of high volume
packaging and assembly companies to low-wage countries such as China and India, the manufacturing industry in Europe
needs to revitalise itself by encouraging design and innovation that will allow European companies to produce assembly
equipment and materials of tomorrow that will feed into the Asian market. Our approach of using microwave technology in
bonding has significant advantages over technologies made available in the market. In our approach we don’t need a closed
microwave oven. Through the open design we can do the placement, alignment and curing at the same time. The use of this
technology in reel-to-reel manufacturing will be possible. Due to the higher level of integration and significantly shorter cycle
times this new technology will give European packaging companies a clear competitive advantage particularly over their US
competitors. Quality of the bonds will be improved as well due to better selectivity and special designed materials as well as
the precisely adaptable frequency of the microwave. It uses pulsed microwave sources and relies on the selection of a few
resonant cavities frequencies that are jittered (mode hopping). The two characteristics permit not only the avoidance of
electrical discharges through arcing, but also the accurate curing of the paste at the location of interest, i.e. at the interface
between a die and the substrate for example in the case of DCA. The project is driven by 5 SME-IAGs who want to create
this clear competitive advantage for their members. The SME core group involves companies who typically are involved in
the in the value chain of packaging including paste design, component and precision equipment manufacturing, system
integration and end users. The expertise of the consortium has been put together in order to gain rapid and pervasive
technology adaptation.
