Eagan, MN — Ironwood Electronics is continuing to design and manufacture new Grypper “Y” test sockets for industry-standard eMMC and univer- sal flash storage (UFS) memory devices. The new Grypper socket, part
Ironwood: Grypper “Y” Sockets for eMMC and UFS Devices
number 113036-0003, allows testing of the newest generation (UFS) 153 BGA form factor and all eMMC devices. The socket fits 0.45 x 0.51 in. (11.5 x 13 mm) devices. The socket can accommodate smaller sizes with the use of a drop-in alignment frame. The Grypper Y socket will typi-
cally fit into the same location and footprint as the device, allowing development and failure analysis. Although the socket body is larger than the device, the area around the device size is cantilevered, allowing most other devices to fit underneath. The socket is mounted using
standard soldering. Force required for device insertion is preset by springs in the lid to approximately 0.9 oz (25g)
SCHURTER Launches SMD Circuit Protector
Santa Rosa, CA — SCHURTER has launched a pulse-proof SMD ceramic fuse with super time-lag tripping char- acteristics, the UMT-W. The fuse is particularly useful as a fail-safe device in demanding applications. The cuboid-shaped, extremely
compact, 0.2 x 0.6 (5.3 x 16 mm) SMD fuse is available in five rated currents from 5 to 20A and reaches rated volt- ages up to 125V AC and DC, with a breaking capacity of up to 1,000A. The fuse is also designed to have a slow, precisely defined melting behavior.

per contact. Devices can simply be inserted into the socket and the “KeyLock” lid slid on. The spring- loaded press in the lid is released using a common hex wrench. The Y shape of the contact gently contacts the solder balls of the device, allowing hundreds of insertions. The socket also demonstrates
excellent electrical performance of 1 dB insertion loss up to 40 GHz. The socket is sold in three configurations: sockets with RoHS solder balls; sock- ets with SnPb solder balls; and with- out solder balls. The RoHS version (SAC 305) replicates the device for
attachment. The socket configured with SnPb solder balls allows for

easy reflow and attachment on PCBs that already have components mounted. The lower melting temper- ature of the SnPb solder will not affect any adjacent components. The version with no solder balls
requires the use of a 0.008 in. (0.2 mm) stencil for the correct amount of solder paste, allowing any type of solder
paste the customer prefers to be used. Contact: Ironwood Electronics,

UMT-W SMD ceramic fuse. The UMT-W is recommended
for use wherever high-inrush cur- rents flow (e.g. motor control sys- tems), which are often primarily pro- tected by an electronic fuse. If this monitoring fails, or does not perform its task correctly, the fuse takes over as a fail-safe device and transfers the system to a safe, current-less state. The fuse is a “COTS+” product.
The “+” comes from extended fuse qualification tests (e.g. AEC-Q200) and highly controlled manufacturing processes, which are available to all SCHURTER customers. For higher reliability requirements, the company offers visual inspection according to MIL-PRF 55342, burn-in and various
up-screenings, and test reports. Contact: SCHURTER, Inc., 447
