Edgecards Boast Gold-Plated Contacts to Ensure Performance in High-Reliability/High-Cycle Applications

San Marcos, CA, July 16, 2008…Sullins Connector Solutions, Inc., a global leader in the design and manufacture of RoHS-compliant board level interconnect products, today announced the availability of a comprehensive series of male edgecard connectors designed to simulate 0.062” (1.58 mm) thick daughtercards. The parts provide engineers and assembliers with a durable 0.100” (2.54 mm) or 0.156” (3.96) spacing interconnect system when mated with a Sullins or comparable female edgecard. The double-row connectors notably feature phosphor bronze gold-plated contact fingers that can eliminate the need for gold plated fingers on the daughtercard. Supplied in dip solder, straight, or right angle for through hole, and card-extender for straddle mount terminations, they facilitate optimal design flexibility while ensuring robust and reliable connections in high-temperature applications. Materials are UL94V-0 rated. Parts are available with a choice of PBT or Nylon 9T insulators. The series features an operating temperature range of -65 degrees C to +150 degrees C, and a processing temperature of 260 degrees C peak.

The male edgecard connectors are ideally suited for employment in an array of high-temperature, high-cycle life applications in which the circuit connection of PCBs or wire harnesses to 0.062” daughtercards are required. They are most commonly specified for use in test and burn-in ovens, along with communication systems, process control, medical equipment, instrumentation, and automotive R&D. Devices can also be configured as a test cable for a PCB in the absence of a daughtercard.

Connectors with 0.100” centerlines are offered with from 4 to 60 contact positions, while 0.156” centerline devices may be ordered with from 4 to 40 contact positions. The parts’ phosphor bronze contacts are provided standard with 10΅” or 30΅” overall gold over 50΅” nickel. Tail options include 100΅” pure tin or 5΅” gold. Additional specifications include a current rating of 3 Amps per contact, and an insulation resistance of 5,000 Megaohms minimum at 125 VDC. They may be ordered with tail (contact) lengths ranging from 0.100” (2.54mm) to 0.560 (14.22mm), and with or without mounting ears.
