Test & Measurement: Clip "Piggybacks" Onto TSOPII SDRAMs To Simplify Testing

The QUAD-4 ClipT is designed to clip over surface-mounted double-data-rate SDRAM memories in thin small-outline (TSOPII) packages to ensure a mechanically accurate, non-invasive contact with the package leads. The clip provides access to individual or multiple signals for logic analyzers, oscilloscopes, and other test equipment. It accommodates pin counts of 50, 54, 66, and 86 and lead pitches of 0.80 to 0.50 mm. The QUAD-4 spring probe design snaps (piggybacks) onto the IC package. As the clip is placed on the device, each package leg comes in direct contact with a spring probe, which will be pressed atop the package for a secure electrical connection. The user regulates the clip's tightness by adjusting a miniature screw on each side-latched end. Wire-wrap posts allow for connections to test equipment. Prices start at $820. Delivery is from stock to five days.
