Platings overview
IMD on CATV and Wireless
connectors
Identified below are the most likely factors
that can affect Intermodulation performance in
CATV and Wireless connectors:
Contaminated plating solution
Insufficient plating thickness
Corrosion
Dissimilar metals in intimate contact
Magnetic materials in the signal path
Low contact pressure
Less than 360°
contact
Poor surface finish
Debris and dust within the connector
Convoluted signal path

Silver and
white bronze
Silver and white bronze have the lowest practical resistivity and they are
therefore able to minimize
interface contact resistances, which is ideal
for low intermodulation.
But silver and white bronze are sensitive to
corrosion.
Stainless steel, nickel and ferrites
Magnetic and para-magnetic materials as stainless steel, nickel and
ferrites, only compound non-linearity and give poor interface contact resistance, which gives
low intermodulation.
During experimentation a degradation in performance of 20 dB was
discovered, when nickel plate was used in stead
of silver.
Nitin-6
Nitin-6 plating has excellent protection in
all environments against corrosion and much better corrosion resistance
than silver and white bronze.The
Nitin-6
plating has proved to be extremely stable and resistant
over many years of operation in hard climatic environments. Our salt
spray tests have shown no impact on the Nitin-6
plating or the function of the connector.
Nitin-6
is non-magnetic and resistant to most chemicals.
The Nitin-6 plating has a stainless
steel look, a low
friction surface and
will retain lubricant well.
Nitin-6 is
non-toxic and does
not cause allergic reactions to nickel allergic persons.

The Plating process
Cabelcon's
customers expect high and long lasting quality, and that is why Cabelcon
has developed a
unique Nitin-6
plating process, where a lot
of different items can be plated in contiguous operations. The system
controls automatically the right time and operation procedure for the each
specific lot.
Apart from Nitin-6
Cabelcon is also
manufacturing silver plated connectors, with silver- or gold plated inner
conductors, as well as other NITIN/silver/gold combinations, depending on
applications and requirements.

Environmental Care
Unfortunately it is not possible to do any metallic plating without the use of chemicals. In
order to ensure minimum impact
on
the environment in the washing process, we use only water and
washing chemicals - not harmful to the environment.
The water used for the plating- and washing process is reused several
times in different washing levels. After extensive use, the discharge
water is being cleaned in our advanced "wastewater cleaning system".
The final discharge water complies with the government environmental
regulations. The remaining contents of metal and chemicals drawn from the
discharge water and used chemicals, go for destruction.
