Ceramics and Ultrasonics
 The
use of a CERAMIC resonator, such as ALU Oxide or Silicon Carbide
makes it possible to design high frequency transducers for wire
bonding with the same power as lower frequency transducers. The
CERAMIC 138, when clamped with tool, becomes 135 kHz. Its also
unique in that it has a second frequency of 97. Used in tandem, the
97/135 produced additional improvements in the quality of bonds.
The Benefits
to the Precision Manufacturer
The CERAMIC advantage is
superior sound, speed, and a surface finish that is without the
voids found in metals. Since the introduction of Ceramically
Enhanced Wire Bonding Transducers thousands of transducers have
been sold.
The CERAMIC 138 resident
anti-resident differential is the best in the marketplace.
Impedance levels of 10-15 are standard for the CERAMIC 138 and have
never been duplicated by metal stacking.

See how Uthe's dual frequency, ceramically
enhanced approach provides more power and control for precise
bonding requirements. If your organization is still using stacked
metal configurations, the time is now to upgrade to Uthe's
ceramically enhanced method.

Uthe is the Market Leader
Since 1966, Uthe
Technology has been the acknowledged leader in the design
and manufacture of ultrasonic generators and transducers for
ultrasonic and thermosonic wire bonders. With over 60,000 units
installed worldwide, Uthe has supplied the
Semiconductor industry with more generators and transducers than
all other manufacturers combined.
Uthe Customers
Consist
of more than 500 different end-users of the company's ultrasonic
power supplies and transducers. In addition, 90 percent of the
company's OEM sales were made to a number of bonding machine
manufacturers including ASM International; F & K Delvotec S.A.;
Dias Automation Ltd.; Marpet Industries, Inc.; Hybond, Inc.; SMH
(Taiwan); ESEC; Mitsubishi, Hesse and Knipps, and many other
equipment manufacturers.
Other customers include captive semiconductor manufacturers who
produce bonding machines for their own use or for resale, such as
General Motors, Philips, Hitachi,
IBM, Texas Instruments, and Toshiba.
