XBT sockets are small footprint sockets - 0.4 & 0.5mm for BGA, LGA, QFN, QFP, SOIC.

The socket needs only about 2.5mm extra space around the chip than the actual chip size utilizing only very small PCB real estate.

A clamshell lid with a wave spring provides the compression force. This mechanism provides easy chip replacement and is compatible with automated handler system also.

If heat dissipation is of concern, a heat sink can be integrated in the middle of clamshell lid to dissipate up to 100 watts.

XBT sockets use XBT contact technology for high endurance and wide temperature applications. The XBT contact is a machined contact with outside spring that provides a robust solution for Burn-in & Test applications.

XBT contact technology has a 3 part system which includes top plunger, bottom plunger and a spring. The brass plungers are machined, plated and assembled to a stainless steel gold plated spring inside a high temperature plastic cavity eliminating the need for an external shell or barrel.

Typical specifications for the XBT contact technology include:

Over 10GHz bandwidth @-1dB for edge pins

Contact resistance under 50m

Self inductance under 1nH

Capacitance under 0.3pF

Operating temperature range -55C to +150C

Insertion/Extraction life over 10, 000 cycles

Current rating at 30C temperature rise is 2 Amps per pin

Three Mounting Options:

Using hardware in which holes are needed for screws and can be positioned on the target board.

If the holes cannot be drilled on the target board, epoxy mount sockets are the other option. Epoxy mount sockets use epoxy and special mechanism to mount the socket on the target board.

The third option is using SMT emulator base. The SMT emulator base has balls on the bottom side that precisely matches the device array and has hardware for socket mounting.

XBT sockets are small footprint sockets and compatible with our GHz elastomer, spring pin socket line. Custom design and short lead time is our specialty.
