RF Coax Connectors
Appendix B - White Bronze (Continued)
White Bronze is available on all
products, including 7-16, N, TNC,
OSP and SMA.
Low Coefficient of Friction
The coefficient of friction
is approximately 70% that of
silver to give lower insertion
forces and smoother
coupling. These properties
combine to produce a
harder wearing, longer last-
ing finish which prolongs
connector life and reduces
the ongoing cost of
ownership.
Tyco Electronics’ White
Bronze
Environmental Test
Four groups of conditioning
tests were performed to pro-
vide a comprehensive evalu-
ation of the Tyco Electronics
White Bronze plated con-
nector bodies. The tests
were performed to the spec-
ifications of the European
and International RF con-
nector standards - CECC
22000/ IEC 68-2-14/IEC 169-
1. Full details and relevant
data are available from
Tyco Electronics and results
are summarized below.
Test 1 - Industrial Atmosphere
& Temperature
Endurance
1.1 Industrial Atmosphere
Exposure to Sulphur Dioxide
Atmosphere (as specified in
IEC 68-2-42 Test Kc) for 21
days of mated connectors,
previously subjected to 500
matings, to determine the
influence of sulphur dioxide
on the corrosion resistance
properties of White Bronze
Plating. Contact resistance
measured after matings
and sulphur dioxide expo-
sure was less than 5%
(0.23mohm) of the permissi-
ble specification.
1.2 High Temperature
Endurance Exposure to
temperatures of 85°C ±5°C
for 250 hours, to determine
the impact of prolonged
high temperatures on plating
adhesion. Prior to testing
the connectors were subject
to 500 matings. Results
showed no visual deteriora-
tion in plating finish (blister-
ing, cracking etc.) and the
results of outer conductivity
performance were compara-
ble to Test 1 (above).
Test 2 - Rapid Temperature
Change & Damp Heat
Steady State
2.1 Rapid Temperature
Change Exposure to -55°C
and +85°C for 15 minutes,
transition time 2-3 minutes,
50 cycles. To determine
possible plating deteriora-
tion caused by prolonged
and rapid temperature
change. No visual deterio-
ration, outer conductivity
performance were compa-
rable with Test 1 (above).
2.2 Damp Heat Steady
State Exposure to 93% rel-
ative humidity (at 40°C) for
10 days. To determine plat-
ing adhesion. No visual
deterioration, outer conduc-
tivity performance were
comparable with Test 1
(above).
Test 3 - Soldering Heat
3.1 Resistance to Soldering
Heat Exposure to concen-
trated soldering heat
(250°C) for 10 seconds to
evaluate any possible dete-
rioration in plating finish.
No deterioration detected.
Test 4 - Salt Mist &
Mechanical Endurance
4.1 Salt Mist
Exposure to salt mist spray
(as defined in BS 2011 Pt.
2.1 Ka) for 48 hours to eval-
uate the uniformity of pro-
tective coatings, any visual
deterioration, or impact on
electrical performance. No
visual deterioration, outer
conductivity performance
were comparable with Test
1 (above).
4.2 Mechanical Endurance
Electrical and visual evalua-
tion of the connectors after
500 matings to determine
any electrical or visual
deterioration. No visual
deterioration, outer conduc-
tivity performance were
comparable with Test 1
(above).
