SUN’s tuning fork aluminum backplanes are designed to meet
the requirements of high performance military, aerospace, and industrial applications. Outstanding long-term reliability is
demonstrated by a MTBF of 4 X 106 years / contact established under field operating conditions. Utilizing tuning
fork contacts, insulators, ground bushings, ground posts, and polarizing keys to MIL-C-28754, the series offer outstanding
interconnection performance in 0.100" grid configurations with two-, three-, and four- row connector patterns of virtually
For high-density LSI applications, special low-force tuning fork
contacts are available to reduce engagement forces by up to 30% below those of standard contacts. These contacts significantly
ease daughter card insertion while providing excellent normal force characteristics, thus maintaining a high level of electrical
and mechanical performance.
For aerospace applications that utilize the backplane as a key structural
element, special milling techniques are available for designs that require high contact density, high thermal dissipation,
lightweight, and high rigidity.
SUN’s tuning fork aluminum backplanes are designed to the
requirements of MIL-C-28754 and WS6157. While they will mate with most well-designed blade connectors, they provide optimal
mating performance and interconnection reliability in conjunction with SUN’s blade connectors.
