Socket Applications.

Loranger Sockets are designed to withstand the conditions of burn-in, test, HAST, humidity and repeated insertions. Below are some of the applications for Loranger sockets.

Fine Pitch

Loranger sockets are available in over 120 different standard and custom contact pitches. Typical pitches include 1.27 mm, 1.0 mm, 0.80 mm, 0.50 mm, 0.40 mm, 0.35 mm, 0.30 mm, 0.25 mm and smaller.

Small Footprint

Loranger Burn-in and Test sockets are designed to have the smallest footprint possible. This allows an increased number of sockets on a burn-in board, and therefore increases the throughput of devices in each test run.

Crystal Oscillator

Loranger sockets can be used for test and burn-in of Crystal Oscillator packages, and are available with plated through hole or surface mount APS contacts. Socket are available for packages including: printed circuit card modules, LCC, DIP SIP, MEMS and QFN. Loranger sockets can also be used as an alternative to "Bed of Nails" test fixtures.
