Tool straightens pins with no static risk
Aries Electronics has introduced the first antistatic version of a tool that provides a fast, easy and inexpensive means of straightening the pins of DIP IC devices.
HF test socket takes two separate packages
Aries Electronics has developed a high-frequency test socket with a replaceable spring probe interposer.
For MLF and QFN packages, the socket also incorporates a raised point probe for accurate placement and scrub on small pads.
With a signal path of only 1.95mm, the new RF socket provides minimal signal loss for higher bandwidth capability.
The new socket's solderless, pressure-mount compression spring probes are accurately located by two moulded plastic alignment pins and secured with four stainless steel screws to ensure fast, easy access for mounting to and removal from the load board.
In addition, the socket's small overall size provides the maximum allowable space for load board components and connectors.
Estimated contact life is over 500,000 cycles.
Centre probe contact forces are 9 to 12g per contact for 0.50 to 0.75mm pitches, and 17 to 20g per contact for 0.80mm pitches and larger.
The new RF test socket's operating temperature is -55 to +150C.
The compression spring probes are heat-treated beryllium copper alloy, plated with 0.75um gold per MIL-G-45204 over 0.75um nickel per QQ-N-290.
The socket's moulded components are UL94V0 Peek and/or Ultem and machined socket components are UL94V0 Ultem or Torlon.
All hardware is stainless steel.
As with all Aries sockets, the new RF test socket is available in custom materials, platings, sizes and configurations to suit specific customer applications.
Pricing for a 200-lead RF centre probe socket for 3.5GHz applications starts at $500 each for up to four pieces.
Delivery is two weeks ARO.
