Aries Electronics is offering a Kelvin test socket that handles devices with a lead pitch down to 0.4mm. The socket uses two independent Aries Kelvin spring probes per device pad for reliable, low-resistance testing of MLF, QFN, LGA and other leadless devices. With a signal path of only 0.082in, Aries' Kelvin test socket is said to provide minimal signal loss for higher bandwidth capability. The socket's low-cost, two-piece construction and small overall size allows the maximum number of sockets per test board. The operator-friendly, low-profile socket uses solderless pressure mount compression spring probes, accurately located by two moulded plastic alignment pins and mounted with four stainless-steel screws, allowing for easy mounting and removal from the test board. For increased reliability, the gold-over-nickel-plated probes leave small witness marks on the bottom of the device pads. The probes are constructed of heat-treated beryllium-copper with a minimum of 50 micron i...

Rittal has extended its Power System Module (PSM) range to allow the power consumption of individual servers and peripheral hardware to be measured per socket. New plug-in modules for PSM rails record the individual currents for each socket and show the power consumption of the devices connected, via three coloured LEDs on the right-hand side.  A second LED on the left-hand side of the outgoing slots provides an overview of the overall power of the module. The presentation logic is automatically adjusted to the mounting position to rule out any misinterpretation. Colour coding follows the traffic-light principle: green LEDs indicate that other equipment may now be connected safely; amber indicates increased current on the module and that before any other equipment is connected its installed load needs to be examined; red indicates that another consuming device would trigger the overloading of the power supply.  Values can also be viewed on a digital display, enabling administ...
