Nuts and Volts - March 2015

Among the specific features for the lower barrier to product developers are the module’s small size, low cost, pre-certification to global standards, and comprehensive technical support.

The goal of Atmosphere is to enable any OEM to quickly and painlessly turn a mobile Bluetooth smart device — such as an iPad, iPhone, or Android-based device — into a mobile control panel.

ETHERNET-BASED

MULTIFUNCTION DAQ

Measurement Computing Corporation has announced the release of the E-1608: an Ethernet-based multifunction Data Acquisition (DAQ) device. The E-1608 provides both analog and digital I/O, and is priced at $499.

The E-1608 features 250 kS/sec sampling and 16-bit resolution. It offers eight analog inputs, eight digital I/O, one counter input, and two analog outputs. The device is supported in Windows and Android operating systems; Linux support will be added in the near future. An OEM board-only version is also available.

Microsoft Windows software options for the E-1608 include DAQami and TracerDAQ® to display and log data, along with comprehensive support for C, C++, C#, Visual Basic, and Visual Basic .NET. Drivers for DASYLab and NI LabVIEW are also provided.

Android support for the E-1608 allows users to develop DAQ applications for tablets and smartphones.

Free sample applications are available for download on Google Play™.

SOCKET & TEST QFN74 DEVICES WITH EXTREME TEMP SOCKET

Ironwood Electronics recently introduced a new stamped spring pin socket addressing burn-in test requirements for testing 74 lead QFN - CBT-QFN-7038s. The contactor used in the CBT- QFN-7038 socket is a stamped spring pin with

15 gram actuation force per ball with a cycle life of

10,000+ insertions. The self inductance of the contactor is 0.98 nH, insertion loss < 1 dB at 10

GHz, and capacitance

0.03 pF. The current capacity of each contactor is 2. 2 amps. Socket temperature range is - 55°C to +155°C.

The socket also features a clamshell lid for easy chip insertion and removal. It has a wave spring with swivel compression plate for vertical force without distorting device position. The specific configuration of the package to be tested in the CBT-QFN-7038 is a QFN, 4. 5 mm x 12. 5 mm, 0.4 mm pitch, with 74 peripheral positions with an additional 6x3 array of pins for the center ground pad. The socket is mounted using supplied hardware on the target PCB (printed circuit board) with no soldering, and uses the smallest footprint which allows inductors, resistors, and decoupling capacitors to be placed very close to the device for impedance tuning.

To use, place the QFN device into the socket and close the lid by snapping it to the latch. This socket can be used for quick device screening and device characterization at extreme temperatures, as well as for production burn-in testing. Pricing for the CBT-QFN-7038 is $603 (at qty 1) with reduced pricing available depending on the quantity required.
