Ultrasonic metal weldingfor power electronics and cell contacting systems
About us Power electronics / cell contacting systems
Our 300 employees worldwide develop and produce innovative ultrasonic welding machines - and,
together with our representatives, are always close to our customers. In addition to our headquar-
ters in Wettenberg (Germany), we have locations in Graevenwiesbach (Germany), Boston (USA), Mo-
scow (Russia), Kenitra (Morocco) and Taicang (Jiangsu Province, China). We also have a global sales
and service network.

Ultrasonic welding in the field of power electronics
In the field of power electronics increasingly high-performance
modules such as IGBTs (Insulated-Gate Bipolar Transistors) or IPMs
(Intelligent Power Modules) are produced with the help of ultrasonic
welding. Ultrasonic welding of the load and control connections to
substrates (e.g. DBC) offers full process and quality monitoring com-
pared to conventional soldering.
In reliability tests, ultrasonically welded power modules last up to
ten times longer. The intermetallic connection leads to a significantly
reduced power dissipation at the contact points, which increases the
electrical efficiency of the module and minimizes the cooling effort.

DS20-S-plus FX20-L
DS20-S-plusThe manually operated ultrasonic welding machine DS20-S-plus is based on
a flexible concept and is suitable for laboratories, prototypes, sample series
production and smaller series production of e.g. power electronics, cell con-
tacting systems or special applications.
i
FX20-LThe FX20-L is a semi-automated ultrasonic welding machine for production. It is suitable for wel-
ding power electronic modules (e.g. IGBT modules) or cell contacting systems (battery applications).
The machine is available with a pattern recognition system for checking and correcting the welding
position and an external particle cleaning system.
¬ Ultrasonic welding head: 20 kHz (35 kHz available on demand)
¬ Working area: x-axis: 250 mm, y-axis: 400 mm - turntable: 360°
¬ special stiff axis systems resistant to ultrasonic vibrations
¬ Accessibility z-direction: max. 62 mm - special long welding tool available
¬ Ultrasonic welding head: 20 kHz (35 kHz available on demand)
¬ Working area (x-y-table): x-axis: 100 mm, y-axis: 250 mm (manually with crank handles)
¬ special stiff axis systems resistant to ultrasonic vibrations
¬ Accessibility in z-direction (sonotrode): max. 62 mm
All machines are equipped with a quick-change system for welding tools and a
patented dynamic process monitoring system. The latter monitors the power and
height curves and provides adjustable tolerances for welding time, height, energy
and deformation for each welding spot.

FX20-2L-RThe FX20-2L-R is a flexible and fully automated ultrasonic welding machine for
welding power electronic modules and cell contacting systems. Numerous options are available for
the machine, such as an internal particle cleaning system, robot loading and component feeding via
conveyor system.
Specifications
FX20-2L-R Specifications
¬ Two ultrasonic welding heads: 20 kHz (35 kHz available on demand)
¬ Working area (two x-y-tables): x-axis: 250 mm, y-axis: 600 mm. The highly reliable and precise
axles are equipped with a brake system that ensures maximum stability during the welding pro-
cess. The axle system is also designed to withstand ultrasonic vibrations.
