Sullin’s new PCI Express edgecard connectors feature 1.00 mm contact centers
(Product News, 14 May 2008 )
Announced by Sullins Connector Solutions is the expansion of their comprehensive offering of 1.00 mm edgecard connectors to include a full series of PCI Express (PCIe) parts. Designed from the ground up to conform to PCI-SIG specifications, the devices enable user upgrades, and bandwidth support to implement PCIe technology for desktop PCs and server systems. Featuring slots accepting 1.58 mm (0.062”) thick add-on cards, the edgecard connector series consists of six connectors with 1-32 high-speed serial PCIe lanes, each matching different bandwidth capabilities.
These one-piece high-density connectors enable maximum PCB design flexibility and low-cost board assembly processes. The parts are offered with 36(x1), 64(x4), 98(x8), and 164(x16) contact positions in right-angle/straddle mount versions, as well as in vertical/through-hole styles with 230(x24) and 280(x32) positions to support riser card applications. The vertical/through-hole versions may be ordered with a choice of three tail (contact) lengths (2.30 mm, 2.54 mm, and 3.00 mm) to accommodate differing motherboard thicknesses. The right angle/saddle-mount devices are optionally offered with attached ear clips, or pegs. Parts’ serial lanes are comprised of two differential wire pairs which support a data transfer rate of 2.5Gbs in each direction.
Enabling hot plug and hot swap functionality, Sullins’ PCIe series is ideally suited for dense packaging applications requiring the board-to-board connection of 0.062” +/- 0.008” daughtercards to motherboards. They are notably engineered to facilitate precision pin alignment on the motherboard as well as accurate contact registration on the mating daughtercard. Due to this, they may be confidently specified for use in the broadest range of consumer, commercial, and industrial systems including desktop computers, communications equipment, home entertainment, workstations, embedded systems, factory automation, and for graphical interfaces.
Featuring phosphor bronze contacts, the edgecard connectors are offered standard with gold flash over 50µ” nickel on contact area; 100µ” (min.) tin over 50µ” nickel on termination end. Optionally, customers may select 10µ”, 20µ”, or 30µ” overall gold over 50µ” nickel on contact area. Parts are available in black, blue, green, or purple.
