Test socket promises minimal signal loss
Socket is ideal for manual high-speed testing of devices such as CSP, micro-BGA, DSP, LGA, SRAM, DRAM and Flash, with pitches as low as 0.40mm.
Aries Electronics has developed a new high-frequency centre probe test socket for devices up to 13mm square Available in four versions with ratings of 1-3, 3-5, 5-9 and 10-18GHz, the new socket is ideal for manual high-speed testing of devices such as CSP, micro-BGA, DSP, LGA, SRAM, DRAM and Flash, with pitches as low as 0.40mm

HF test socket takes two separate packages
Aries Electronics has developed a high-frequency test socket with a replaceable spring probe interposer.
The socket's solderless pressure-mount compression spring probes allow the socket to be easily mounted to and removed from the test board.
The four-point crown ensures "scrub" on solder balls for reliable contact mating and its raised tip probe works with LGAs, MLFs and other socket types.
The socket's gold-over-nickel compression spring probe screws leave very small witness marks on the bottom of the device solder balls and are accurately located by two moulded plastic alignment pins and secured with four stainless steel screws.
Aries' new socket provides minimal signal loss for higher bandwidth capability via a signal path of only 1.95mm.
With an overall size of 30.48 x 21.34 x 11.18mm, the socket provides the maximum allowable space for board components and connectors.
The compression spring probes in Aries' new RF sockets are constructed of durable heat-treated beryllium-copper alloy, plated with at least 0.75um gold per MIL-G-45204 over at least 0.75um nickel per QQ-N-290.
The socket's moulded components are UL94V0 Peek or Ultem.
All hardware is stainless steel.
The socket's contact forces are 16g per contact on a 0.50mm pitch, 25g per contact on a 0.50-0.75mm pitch and 25g per contact on 0.80mm or larger pitch.
Operating temperature is -55 to +150C, and estimated contact life is more than 500,000 cycles.
One-off pricing for a centre probe test socket with up to 50 positions starts at US $330.
Delivery is four to six weeks ARO.
