3D-MID Enables Today’s Miniaturized Medical Devices
By Michael Allen Deckert, Marketing Manager, HARTING
devices. One area where this freedom is being taken advan- tage of is in medical technology. Japanese corporation Yaskawa coined the term mechatronics in 1969. Since then, steady develop- ments in technology, such as in drive systems and wireless con- nectivity, have significantly expanded its usage. Today, medical devices are a

major focus of mechatronics. One of its breakthrough innovations are Mechatronic Integrated Devices (3D-MID). It’s a technol- ogy that allows higher density integration of electronic compo- nents into the smallest possible space. When it comes to minia- turization, the ideal partner is one like leading 3D-MID suppli- er HARTING. The company is located in the innovative heart of the Swiss watch industry in Biel, which is also a growing hub for medical device technologies. This location was chosen with care, because in this region people have grown up in a world of micromechanics — generation after generation.

3D-MID 3D-MID, or 3D circuits, have
the potential to transform the medical industry as we know it. As medical devices such as hear-
require much more delicacy and precision. HARTING’s 3D circuits
make it possible to combine mechanical and electronic func- tions into a single component to
process steps, assembly times, and parts can be drastically reduced. Device designers can go
above and beyond the limits of traditional manufacturing with the help of 3D circuits. The sky’s the limit when electrical and mechanical functions can be uni- fied in a single three-dimension- al component. These components are con-
structed using very malleable bits of plastic through injection molding. This process makes it possible to create anything with precise measurements according to the requirements laid down by final customer usage. Injection molding is perfect

A process called laser direct structuring (LDS), devel- oped by LPKF Laser & Elec - tronics in 1996, can then draw the needed electrical trace layout to these components, which will be made conductive in a subse- quent chemical plating process.

TAKING THE NOISE OUT OF E-MOBILITY
Noise free e-mobility
e-Mobility is no longer a question of tomorrow and the number of e-vehicles is increasing day by day. Handling EMI noise is becoming more and more crucial, when it comes to design new electronic devices and systems. Würth Elektronik offers a wide range of EMC components, which support the best possible EMI suppression for all kinds of e-mobility applications. With an outstanding design-in support, catalogue products ex stock and samples free of charge, the time to market can significantly be accelerated. Besides ferrites for assembly into cables or harnesses, Würth Elektronik offers many PCB mounted ferrites and common mode chokes as well as EMI shielding products.
