would be “more science fiction like, very interactive in the way people will get information about what we do”.
“They have a certain form factor that is not very compact and not very scalable, and they use wire bonded technology,” he said. “There can be hundreds and thousands of these wire bonds, and these have inherent limitations.” Not only can they suffer from fatigue and
failure, they are also not very scalable as designers try to make the IGBTs smaller and lighter. He will thus be discussing solderable front metal die as an alternative. “We solder the piece of silicon to a circuit
board,” he said. “That eliminates the wire bond joints altogether. This also reduces the size. And you can get a good physical connection on the under side and the top side of the die.”
He said that while there were two or three other companies working on using solder, the method he was proposing was the only one to use dual-sided cooling, which helped to improve power density.
Challenge from China
Benjamin Jackson: “Having all the disciplines in one place is not a bad thing.”
He said the normal coffee and sausages will still be available and there would be some specific demonstrations, “but not in the way that you are used to”.
The firm’s main focus, as one would expect, will be on sensors and the company will be launching a family of rotary magnetic position sensors for industrial markets.
“It is always good to have something new at the show,” said Gessner. “There is a lot of information coming across but we have to let people know what we are going to be doing in the future.”
IGBTs in automotive In his talk, International Rectifier’s Jackson will be tackling a growing problem of how IGBTs originally designed for industrial and air

conditioning applications are making the transition to automotive with the growth of electric and hybrid electric vehicles (EVs and HEVs).
more obvious than in the automotive sector where China has a high percentage of young drivers who have grown up with smartphone technology and expect the equivalent in their vehicles. “We have seen very clearly in the past few years that there has been more variety and this is because of the growing needs of the customers,” said Klaus Zimmer, senior vice president of Neusoft. “The buyers there are much younger and that is driving innovation. The average BMW driver is under 30 compared with 60 in some places in Europe.” Zimmer’s talk will explain how the connected car is becoming a reality in China and how the car manufacturers are using that experience to bring the innovations to a global market. “True mobility will see mobile and automotive technologies merging,” he said. “The young have very specific needs. That is passed to the car makers and they have to think about it. In China, they have to be much more alert as to what the drivers need and this is driving the global demand for innovation.”
One topic that will cover all the disciplines at Electronica will be the growing influence of China, not just as a cheap place to manufacture (and it is not that cheap any more) but as a source of innovation that will influence the rest of the world. Nowhere is this

the semiconductor market,” he said. “The main semiconductor companies are in Silicon Valley, Japan, Korea and Taiwan, but they are not in China. I think we could see that change. The government is interested in investing in this field.”
He said the Chinese were no longer happy with depending on other companies and wanted to make a name for themselves.
Another move that could come from China in the coming years is for it to have home- grown semiconductor companies with their own fabs, believes David Bagby, president of Alliance Memory.
“I talk to a lot of people in China and I do think China is interested in trying to get into
David Bagby: “We had meetings with fifty customers last time.”
Bagby’s company will be back with a stand
at Electronica after getting a large return on investment last time out. “We had meetings with fifty customers last time,” he said. “Our distributor network is also very strong in Europe and they will be there as well. It is a good opportunity to see our sales force.”
