Four-Pin USB "A" Connectors Feature 12-Mbit/s Performance
The devices in a recent line of USB connectors are configured for the "A" version of the USB standard. They feature four in-line pins of brass or phosphor bronze, plated with nickel and finished with a gold flash. Two of the pins are intended for power, while two are for signals over twisted pairs. Also, these connectors sport a 12-Mbit/s or better bandwidth for connectivity between high-performance PCs, Internet service providers, and high-speed data-storage units.

These connectors cost $0.20 each in 50,000-unit quantities. Delivery is from stock to four weeks ARO.

BGA/LGA Socket Family Targets 6-GHz, Small-Footprint Systems
Designed for high-volume production test applications, prototyping systems, and field-upgradable designs, a recent series of BGA and LGA sockets supports high packaging densities and system speeds up to 6 GHz. The line's zero insertion force (ZIF) chip placement system can withstand up to 100,000 insertion cycles before a simple maintenance procedure is recommended. These sockets also can serve as a heatsink.

A high-performance, conductive elastomer provides IC package contact. This approach supports IC packages with as many as 729 pins and pitch capabilities as low as 0.5 mm. Each socket guides the IC to the exact position for connection while using an aluminum heatsink screw to supply compressive force. Additionally, they're just 2.5 mm per side larger than actual IC packages, minimizing footprint while maximizing speed.

These sockets cost $102.54 in 1000-unit quantities. Delivery takes three to five days.

Cable Assemblies And Connectors Support Ultra ATA/100 Technology
The ATAS family of cable assemblies and connectors supports all aspects of the ATA/100 standard. These products feature the same ATA 80-connector grounded cables that currently are used for Ultra ATA/66 drives. They also offer improved data reliability and signal integrity as specified by the Ultra ATA/100 standard, which features built-in 80-conductor cable-detect circuitry. And, the cables are backward compatible with CD-ROM and DVD drives and other ATAPI devices.

Used with the ATAS 80-conductor cable assembly, Ultra ATA/100 hard drives can support burst transfer rates of 100 Mbytes/s. These cables and drives also will work with previous generations of PC-compatible systems to transfer data at the maximum rate these systems will allow. Each ATAS cable, up to a maximum of 18 in., supports up to two devices. New raid controllers will accommodate up to eight IDE-interface storage peripherals when using four ATAS cable assemblies as the required interface.

Devices Let Designers Adapt New SSOPs To Old SOWIC Packages
The Correct-A-Chip adapter family lets designers use new SSOP devices on boards designed for older SOWIC packages without rework or redesign. A 20-pin version (the 20-555000-00) is currently available, and 14-, 16-, and 24-pin models will soon follow. This SSOP package with 0.65-mm pitch can be hand-soldered or reflow-soldered using IR or vapor-phase technology on the adapter's topside.

This completed reassembly then can be pick-and-placed and reflow-soldered to the target pc board with the same methods. A complete SSOP device-to-adapter mounting service is available as well. Additionally, these adapters have an operating-temperature range of −55°C to 125°C. Their pins are built from hardened brass alloy with tin-lead plating.

A 20-pin SSOP-to-SOWIC adapter costs $9.00 in 100- to 499-unit quantities. Delivery is six weeks ARO.

Socket Supports Switches In Board Assembly And Rugged Applications
A low-profile socket for the IS Series Smart Switch simplifies board assembly by enabling automated soldering. After the socket has been processed, the switch is protected from the rigors and heat of automated assembly, thereby safeguarding reliability and functionality. Also, the socket supports quick and easy field replacement while facilitating high-density, side-by-side panel or pc-board mounting of Smart Switches. It permits rigorous automated soldering and washing as well.
