The Tyco Electronics White
Bronze surface finish repre-
sents a dramatic improve-
ment upon the wear
characteristics and life
expectancy of silver plating,
at the same time offering a
far better electrical perform-
ance than nickel. White
Bronze plated connectors
exhibit intermodulation
characteristics significantly
better than stainless steel
or nickel plated products.
Silver has always been the
preferred finish from an
electrical standpoint but its
corrosion and wear charac-
teristics especially in harsh
conditions are often unac-
ceptable. While nickel is an
extremely rugged finish it
has properties undesirable
in many RF applications;
including, high RF and
insertion losses, poor inter-
modulation performance,
high permeability and poor
screening effectiveness.
The Tyco Electronics White
Bronze is composed of
copper, tin and zinc which
are applied simultaneously
to produce a finished color
similar to stainless steel.
With one of the most
advanced industrial electro-
plating facilities in the world
Tyco Electronics can
achieve the levels of control
over the complex galvanic
process necessary in the
application of this alloy.
The Tyco Electronics White
Bronze is similar in compo-
sition and performance to
other copper/tin/zinc alloys
developed in the industry
such as Sucoplate^® and
BBR.
Comprehensive condition-
ing tests have been per-
formed to provide a
thorough evaluation of The
Tyco Electronics White
Bronze plated connector
bodies. The tests were per-
formed to the specifications
of the European and
International RF connector
standards — CECC
22000/IEC 68-2-14/
IEC 169-1. The results are
summarized on page 280.
