exposure from vibrational forces, the patent
pending design of the Sycamore Contact
gives engineers access to three contact points.
This markedly improves operational stability,
as well as delivering stronger pin retention

Whereas other contact solutions of this
Available in both top-entry and bottom-entry
configurations, these sockets have a current
rating of 6A and a 15mΩ (maximum)
contact resistance. Their sturdy construction,
which uses beryllium copper with gold
plating, means that they support 500
mating cycles and exhibit an operational
temperature range spanning from –50°C
to +125°C. As these components can be
supplied in a tape-and-reel format, they
are highly suited to automated production
processes, with the surface mount placement
feet also serving as the pickup areas for pick-
and place machinery. n
There are a wide variety of scenarios where
electronic devices/modules will require
replacement over time (such as depleted
gas sensors or worn-out energy harvesting
transducers). In addition, initial exposure of
these modules to soldering temperatures can
introduce the risk of early failure due to heat
damage. Both these risks show that direct
soldering onto the PCB is clearly unadvisable.
Removal of a failed or damaged module will
prove difficult and could result in scrappage
of the whole board.
The Sycamore Contact series of surface
mount PCB sockets allow odd-form devices/
modules that are not suited to regularly-
spaced socket strip arrangements to be
