Test socket boasts broad coverage
A new test and burn-in socket accommodates device packages from 41 to 55mm2 in applications up to 1GHz.
Aries Electronics has introduced a test and burn-in socket that accommodates device packages from 41 to 55mm2 in applications up to 1GHz The new size, which features a standard moulded socket format, is ideal for the test and burn-in of IC devices such as SRAM, DRAM, DSP and Flash, as well as packages including CSP, MicroBGA, LCC, LGA, QFP, QFN and MLF

HF test socket takes two separate packages
Aries Electronics has developed a high-frequency test socket with a replaceable spring probe interposer.
The socket can accommodate lead pitches from 0.45 to 2.54mm.
A spring-loaded, cam-actuated pressure pad applies force against the device after the socket lid has been closed and latched and the cam is in position.
Reversing the cam removes the force prior to unlatching the spring-loaded lid.
The socket features easy mounting and removal from the burn-in board (BIB) via solderless pressure-mount compression spring probes accurately located by two moulded plastic alignment pins and secured with four stainless steel screws.
The signal path of the new socket during test is only 1.92mm.
At pitches above 0.80mm using a large probe, 1dB of bandwidth at 1GHz can be achieved.
Operating temperature of the socket ranges from -55 to +150C, and estimated contact life is 500,000 cycles.
The socket's moulded components are UL94V0 Peek and/or Ultem.
Compression spring probes are heat-treated beryllium copper alloy, plated with at least 0.75um gold per MIL-G-45204 over at least 1.25um nickel per QQ-N-290.
This gold over nickel plating on the probes leaves very small witness marks on the bottom surface of the solder balls.
The insertion force of spring probe contacts is 9 to 12g per contact for 0.50 to 0.75mm pitches, and 17 to 20g per contact for 0.80mm pitches and larger.
All hardware is stainless steel.
As with all Aries sockets, the new burn-in and test socket is available in custom materials, platings, sizes and configurations to suit specific customer applications.
Pricing for a 50-lead socket starts at $68.25 per unit in quantities of 10.
Delivery is four weeks ARO.
