October 28, 2009 -- Sullins Connector Solutions, Inc. is now offering a series of PCI Express (PCIe) card edge connectors to enable easy implementation of PCIe architecture in desktop computers, communications equipment, workstations, and factory automation equipment.
Billed as highly reliable and durable, the connectors support the PCIe standards for signal and power as well as auxiliary signals at the interface between the motherboard and add-in card. The 1.00 mm pitch, one-piece parts feature slots accepting 1.58 mm (0.062") thick add-on graphics cards for user upgrades and support x1, x4, x8, x16, x24, and x32 contact positions to accommodate a range of bandwidth requirements.
The series is engineered to optimize both design flexibility and manufacturing efficiencies, as devices are provided in a wide range of termination types and mounting styles. The parts' serial lanes are comprised of two differential wire pairs that support a data transfer rate of 500 MB/s in each direction, per lane. The connectors additionally feature a 2.5 GHz clock rate, and a 5 GT/s (gigatransfers per second) bit rate.
Suited for an array of dense packaging, board-to-board applications requiring the connection of a motherboard to a 1.58 mm (0.062" +/- 0.008") daughtercard, Sullins says the PCIe card edge connectors are often specified for use in desktop computers, servers, workstations, storage systems, RAID controllers, fiber channel host-bus adapters, routers and switches. Parts are offered with 36(x1), 64(x4), 98(x8), and 164(x16) contact positions in right angle, surface mount, and card extender versions.
Dip solder straight styles are available in 36(x1), 64(x4), 98(x8), 164(x16), 230(x24), and 280(x32) contact positions. The 230(x24) and 280(x32) versions are used to support riser card applications. Most connectors are provided with a choice of tail length options including 2.30 mm, 2.54 mm, or 3.00 mm, to accommodate differing motherboard thicknesses. For added mechanical support and accurate PCB alignment, devices may be ordered with ear clips, pegs, clamps, or handles.
The PCIe series features a current rating of 1.1 Amp per contact. Additional specifications include an operating temperature range of -55 degrees C to +105 degrees C, and a processing temperature of up to 260 degrees C peak for 10 seconds max. Parts are provided with phosphor bronze contacts, and offered standard with gold flash, 10 micron or 30 micron selective gold plating over 50 micron nickel underplate. Housing material is UL94V-0 rated.
While firm pricing is determined according to customers' specifications, average PCIe card edge connector prices range from $0.25 to $4.80 per unit. Samples and small order quantities are immediately available.
