Kelvin
Test Socket
FEATURES
•LAries unique universal socketing system allows the socket to be easily configured for any package,
on any pitch (or multiple pitch) from 0.2mm or greater, in any configuration, with little or no tooling
charge or extra lead-time.
•For Test & Burn-In of CSP, µBGA, Bump-Array, QFN, QFP, MLF, DFN, SSOP, TSSOP, TSOP, SOP, SOIC,
LGA, LCC, PLCC, TO and any SMT package style made. Also can be compatible with PGA packaged
devices.
•Quick and easy Probe Replacement System: the complete set of probes can be removed and a
new set (interposer) can be inserted quickly and easily. The old set can be returned to the factory for
repair and sent back within one day.
•Low resistance testing using dual independent Aries Kelvin spring-probe technology per device pad
for testing of MLF, QFN, LGA and other leadless devices.
•Socket is easily mounted and removed to & from the test board due to solderless pressure mount compression Spring-Probes which,
are accurately located by two molded plastic alignment pins and mounted with four stainless steel screws.
•The Au over Ni-plated compression Spring-Probes leave very small witness marks on the bottom surface of the device pads.
•Small overall socket size/profile allows max. number of sockets per test board, while

height variations in device thickness.
•Probe blade edge tip for cutting through solder oxide layers.
•Signal path during test only 0.082 [2.08].
