PRODUCT BRIEFS
SPOTLIGHT: ADHESIVES & COATINGS
Dielectric thick film paste
The SD1020 dielectric
thick film paste from
Heraeus Electronics
(West Conshohocken, Pa.)
is insulative technology
for circuits and heaters on
stainless steel used in automotive,
industrial and
consumer-product applications.
The paste combines
design flexibility
with advantages for thick
film heater technology, including high reliability, fast cycle
times, high power densities and precise heating. The
SD1020 provides an effective solution for product engineers
faced with these difficulties. Benefits of the new dielectric
thick film paste include improved production yields
that will deliver cost improvements; optimized paste consumption,
which will help decrease paste/BOM costs; and
expanded capabilities to markets that were previously unattainable
to customers. The SD1020 paste's thermal coefficient
of expansion (TCE) and insulative properties make it
suitable as an ultra-low bowing dielectric for heater on
steel applications, enabling extended substrate sizes, improved
production yields and paste consumption for overall
BOM cost advantages.

Precision power analyzer
Yokogawa's
(Sugar Land,
Texas) new current
sensor element
and upgraded
firmware
for its WT5000
Precision Power
Analyzer are designed to help companies improve performance
when developing or evaluating electronic devices such as electric
vehicle (EV) related equipment or systems for solar and wind
power installations. The new current sensor element runs off the
WT5000's internal DC power supply, making external power
supplies unnecessary. This makes set up for measurements easier
as the only things required are the current sensor and a connecting
cable. Three sensor connection cable lengths are available
- 3 m, 5 m and 10 m (10 ft, 16 ft and 33 ft). This helps take
account of varying test bench layouts, where the power analyzer
may not be located right next to the device under test.

AUTOMOTIVE ENGINEERING
High-temp-resistant adhesives
DELO MONOPOX HT2999 from DELO (Sudbury, Mass.) is a
high temperature stability adhesive that achieves compression
shear strength of 20 MPa at 180°C (356°F). According
to the company, its strength is four times greater than its
predecessor and other products on the market. Developed
primarily for use in the automotive industry and mechanical
engineering, these high-temperature-resistant adhesives are
in demand for use with electric motors and power electronics.
DELO's new structural adhesive can be used above
150°C (302°F). This high-temperature resistant adhesive has
been optimized for bonding magnets in electric motors. The
compression shear strength of bonded magnets (NdFeB) is
20 MPa at 180°C. The bonded joints remain thermally stable
over time. Even after 10,000 hours of storage at 180°C, the
bonded magnets achieve a temperature stability of 20 MPa.

Magnet-free electric motor
Mahle (Stuttgart, Germany) is
currently developing a new kind
of magnet-free electric motor
that does not require rare-earth
elements. This not only makes
production more environmentally
compatible, but also brings
advantages in terms of costs
and resource security. The central
feature of the new motor is
the inductive and thus contactless power transmission, which
allows the motor to operate wear-free and particularly efficiently
at high speeds. According to Mahle, the efficiency is
above 95% at almost all operating points, which is a level that
previously has only been achieved by Formula E racing cars.
Mahle has combined the strengths of its various electric motor
concepts in one product. This new development is scalable,
so it can be used in anything from subcompacts through
commercial vehicles.
