Page 115 Ironwood Intros Latest QFN Socket


Eagan, MN — Ironwood Electronics recently intro- duced a new QFN socket addressing the high per- formance requirements of custom size devices, the CBT-QFN-7053. The contactor is a stamped spring pin with a 14.5g (0.5 oz) actuation force per pin and a cycle life of 100,000 insertions. The self inductance of the contactor is 0.98 nH, insertion loss is less than 1 dB at 31.7 GHz and its capaci- tance is 0.067 pF. The current capacity of each con- tactor is 4A. The socket operates in a temperature range of –55 to +180°C (–67 to +356°F). The socket also has an IC guide for precise


QFN edge alignment. The CBT-QFN-7053 is designed for 5.5 x 6 mm (0.22 x 0.24 in.), 0.4 mm (0.016 in.) pitch QFN packages. The IC is dropped into the socket and its removable lid is closed by latching. Vertical force is applied by the integrat- ed compression springs between the socket lid and compression plate. This socket can be used for hand test, screening modules and custom burn- in applications with the most strin- gent requirements. These socket product lines have


been designed to the JEDEC stan- dard and are available for all stan- dard configurations. Custom designs are also available. The CBT-QFN-


KEMET Adds Automotive Qualification


to Capacitors Simpsonville, SC — KEMET is extending its U2J dielectric to auto- motive-grade applications. With AEC- Q200 automotive qualification, the U2J surface mount (SMD) plat- form offers more than twice the capacitance available in C0G/NP0. It also offers superior temperature per- formance over X7R, X8R and X5R, rendering it an excellent capacitor solution for vehicle applications. U2J parts are well-suited to the


stringent demands of automotive systems. Their superior performance versus other technologies can help designers overcome challenges in cir- cuits that require low loss, noise reduction, critical timing require- ments, and improved capacitance stability. Designed for use in environ-


ments with operating temperatures ranging from –55 to +125°C (–67 to +257°F), U2J capacitors only experi-


7053 socket has a special contact design with out- side spring and flat stamped plungers that provide a robust solution for burn-in and test applications, along with excellent electrical signal integrity. The socket is mounted using supplied hard-


ware on the target PCB with no soldering, and has a small footprint. The small footprint allows induc- tors, resistors and decoupling capacitors to be placed very close to the device for impedance tun- ing. The removable socket lid also incorporates a quick installation latch so that ICs can be changed


out quickly. Contact: Ironwood Electronics, 1335

ence small, predictable and linear capacitance changes in response to different temperatures. Also, U2J- based parts retain over 99 percent of nominal capacitance at full rated voltage, and with low ESR and ESL, can handle very high ripple currents. These new devices are lead-free, and RoHS- and REACH-compliant with- out exemptions. U2J SMD MLCCs are available in both commercial and automotive grade and with a flexible


termination option. Contact: KEMET Corp., 2835
