Aries' New Cost-Effective CSP/MicroBGA Test and Burn-In Socket

Frenchtown, NJ, July 2003� Aries Electronics, an international manufacturer of standard, programmed and custom interconnection products, now offers a BGA/CSP test and burn-in socket for devices with a pitch from 0.50 mm or larger in applications of up to 1 GHz. The new socket features a standard molded socket format that can accommodate any device package up to 13 mm2. It is ideal for test and burn-in of CSP, MicroBGA, DSP, LGA, SRAM, DRAM, and Flash devices.

The socket incorporates solderless pressure-mount compression spring probes accurately located by two molded plastic alignment pins and secured with four stainless steel screws, making for easy mounting to and removal from the burn-in board (BIB). The pressure pad compression spring provides proper force against the device and allows for height variations in device thickness. The socket�s small overall size allows the maximum number of sockets per BIB, and BIBs per oven, while allowing easy access for fast device insertion and removal.

The socket can accommodate up to 500,000 cycles. Spring probe contacts are 9 g to 12 g per contact for 0.50 mm to 0.75 mm pitches, and 17 g to 20 g per contact for 0.80 mm pitches and larger. Operating temperature of the socket ranges from -55�C to 150�C

(-67�F to 302�F). The socket�s molded components are UL94V-0 Ultem and machined components are UL94V-0 PEEK. Spring probes are heat-treated beryllium copper alloy, plated with 30 �� min. (.75 �m) gold per Mil-G-45204 over 30 �� min. (.75 �m) nickel per QQ-N-290. All hardware is stainless steel.

As with all Aries sockets, the new burn-in and test socket is available in custom materials, platings, sizes and configurations to suit specific customer applications.

Pricing for a 100-lead socket starts at $175 in single piece quantities. Delivery is

2 weeks ARO.
