Inlay contact finish
A means of applying precious metal to the contact area
utilizing pressure as opposed to conventional plating. We
have found this to be the most durable finish available
without compromising the electrical performance of the
contact. Our research has shown that our inlay finish
lasts over ten times as long as standard gold plating.
Where we state the life of the precious metal this is
intended to be the “worst case” scenario, because the
test has been made using the most abrasive smart card
that we can find on the market (given that the equipment
maker can rarely control which smart cards are used).
Note that the inlay finish is silver in color, being an alloy of
gold, silver, and palladium.
Contact design
The geometry of the contact has an important bearing on
its electrical performance. Our contacts are designed to
give an efficient wiping action and to maximize the stress
between contact and card, thus minimizing the contact
resistance. The “spooned” contact area is also shaped so
as to protect it from damage during card insertion.
Materials
The contact material has been chosen because of its
resistance to atmospheric pollution, solderability and
performance over time in giving a consistent normal
force. Since all of our new interconnects are designed
for surface mounting, the plastic materials used must
withstand high temperature soldering processes without
deforming or adversely af
fecting performance.
C&K Components has a successful track record of manufacturing innovative interconnect devices with a strong
emphasis on reliability and flexibility. As a long established supplier of such devices for Smart Cards in a wide range
of applications, we have extensive experience matching performance with the need to remain cost sensitive. We
consider the true cost of the interconnect to be a function not just of price, but also the ease with which the device
can be integrated into the customer's production process and its performance in the field. We have built in a number
of features which set our products apart, such as:
Card detection switches
As a manufacturer of switches as well as interconnects,
we have been able to integrate high performance dome
switches into many of our devices. These are variants of
switch products which are already in high volume
pr
oduction as stand alone components.
PCI (security standard for POS applications)
Two levels of PCI compatibility level are available:
PCI ready:
Specific features are designed in the connector in order
to ease the integration of security devices around and
below the connector.
PCI:
Additional accessories ar
e integrated on the connector
in or
der to avoid access to the data contacts and to
detect any connection attempt.
Mechanical robustness
Four metal pegs, to be soldered in PCB metalized holes
at the same time than the SMT terminals, have been
designed on the smart car
d connectors in or
der to
incr
ease the resistance of the connector to card insertion
force. This participates to the life time and to the overload
resistance.
