New mobile phone functions fit into a smaller space than before

05.04.2002


Even a conventional mobile phone user demands more functions and better performance of his mobile phone in the smallest possible space. The mobile phone should also be easy to use, reliable and inexpensive. In order to meet these demands, more data and functions than before must be packed into the circuit boards of mobile phones in the future.



The researchers at the Helsinki University of Technology have met this challenge by developing a new type of production method for electronics, a so-called IMB (Integrated Module Board) technology. Due to this technology, the performance of an electronics product is improved, more functions can be added to a smaller space than before and the reliability of the mobile phone is improved further.

"When we started to develop miniaturised electronics products, we wanted to get rid of the casings of the microchips to be packed onto the circuit board, because they took up too much space. The size of conventional microchip casings may be ten times as big as the actual microchip," Professor Jorma Kivilahti, the director of the Laboratory of Electronics Production Technology of the Helsinki University of Technology, explains.


"In the new IMB technology the components are integrated into the circuit board. A module manufactured in this manner is smaller and its electronic properties are better than those of the present component boards. The IMB module is fabricated by using photo definable polymers and fully additive electroless plating processes," Professor Kivilahti states.

"Electrical contacts are made of copper metal in connection with the manufacture of the module`s circuit wiring. Thus no soldering is used in the contacting of components. The present assembly techniques for electronics components are based on soldering."

This new technology will perhaps be available to the conventional mobile phone user in four or five years` time. The Helsinki University of Technology has transferred the rights of the technology developed by it to Aspocomp Oy and Elcoteq Networks Plc., who participated in the project. The task of these companies is to develop and productify production techniques. Nokia has also participated in the development of the new technology.

The IMB technology has been developed as part of the EXT technology programme financed by Tekes, the National Technology Agency of Finland.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
