San Jose, Calif. - Taking aim at new socket requirements for fine-pitch ball-grid arrays, Yamaichi Electronics USA Inc. has launched an open-top 0.5-mm fine-pitch BGA socket as part of the IC398 Series.
The socket features a smooth contact tip in a rounded cup shape, which minimizes ball damage while providing good contact force. The open-top design aids automatic load and unload by enabling easy actuation.
The IC398 series contact was designed for surface mounting. The socket's contact tail can be fanned out to a larger pitch using the pitch conversion board. Pricing for a typical 289 contact socket at a 0.5-mm pitch is about $175 each per 1,000 pieces.
