The family of PXI instrumentation supporting extended boundary Scan Test strategies includes digital I/O modules, a mixed Signal I/O module and several power modules.
The family of digital I/O modules includes the PXI 5296 with 96 channels and the PXI 52196 with 192 channels. I/O channels are individually programmable as input, output, bi-directional or tri-state. The 32 channel groups are voltage-programmable between 1.8 and 5VDC. Each channel features a special protection circuitry to avoid interface damages due to high fault currents, and allows hot-swap capability. A differential I/O module PXI 5384 with 48 programmable channels is available.
The mixed signal I/O module PXI 5702 has two channels with 12-bit resolution for the generation or measurement of voltages. Can also be used as digital pin driver.
The PXI 5120x series of power modules includes five different models (3VDC, 5VDC, 12VDC, 24VDC and 48VDC). All have two separate channels with 50W output power each, and are voltage and current programmable. Feature galvanic isolation, load rejection relays, U/I read back and programmable current. Have an integrated U/I recorder per channel, synchronously operating to the BScan TCK clock.
The new suite supports the PXI trigger bus and, can be synchronized to the boundary scan test procedure.

DEK (dek.com) has developed machine interfaces to NPI and MES software tools from Aegis Industrial Software Corp. (aiscorp.com), allowing engineers using DEK screen printing platforms to reportedly maximise machine uptime, improve process monitoring and reduce operator mean time to assist (MTTA).
DEK screen printing platforms can now communicate using the Aegis xLink protocol, which allows users to reduce machine programming time for through-hole and surface mount production and inspection process machine interfaces using CircuitCAM, and to benefit from browser-based remote monitoring using iMonitor. The two utilities are part of Aegis' software for managing manufacturing information, which encompasses manufacturing activities from NPI to monitoring and optimising production.
CircuitCAM allows users to quickly create machine programs from CAD design information, working offline to maximise machine uptime. Enables generation of process routing, visual assembly documentation and reports from the input CAD information.
iMonitor collects, analyses and archives real-time data from the screen printer, as well as downstream assembly and test equipment. This information may then be used to improve quality and throughput, detect and react to problems before they escalate, analyse and prioritise problems for optimal corrective action, and to inform continuous improvement activities.
Bellows Falls, VT -- Straight cable, coiled cords and high performance flexible products that meet current environmental requirements are available for a range of medical and commercial interconnect applications. Comply with environmental directives such as RoHS and WEEE.

Featuring ProfitPro, an Excel-based software application that calculates the cost and profit related to PWB assembly, the SMTA Cost Estimating Guidelines are intended to model real-time cost estimating (RTCE) in the electronics industry. The guidelines are arranged by Dr. Ronald C. Lasky, Indium Corp. of America/Dartmouth College.
Using these production variables such as cycle time, hours/shift, shifts/day, days/week, set up time and dowtime, ProfitPro can model RTCE for high-volume, low-mix to low-volume, high-mix lines. Has default values of unknown cost metrics, can calculate "what-if" scenarios, including:
- The amount of profit gained if setup time is reduced.
- The amount of profit gained if cycle time is decreased.
- The amount of profit gained if new equipment or materials increases productivity.

National Physical Laboratory has developed a new instrument for measuring solder properties. The advent of lead-free alloys makes it imperative to obtain accurate material properties on volumes of materials under 1mm^3. Instruments must be able to measure and displace small distances, typically a few micrometers to a precision of 0.1µm, and to measure low forces.
NPL has developed a machine that achieves this capability. Measurements are now possible at typical stresses and strains found in solder joints, resulting in realistic fatigue and creep rates. These values are essential for accurate, statistically based life-time predictions of lead-free reliability.

Cogiscan's feeder setup validation system is reportedly robust and flexible enough for use on all different machine types. The RFID Smart Feeder system can be retrofitted to an existing placement machine in the field. The customer's inventory of feeders can be converted into "Smart" feeders by attaching a low-cost RF tag to each feeder.
Key features:
- Enables closed-loop feeder and component setup validation
- Eliminates human errors and reduces changeover time
- Provides real-time material inventory and traceability
- Quick and easy retrofit on any machine type
- Proactively scans all feeder slots in real time.
Can be used in combination with Cogiscan software applications. Can be integrated with feeder set-up verification software from third-party suppliers to eliminate manual barcode scanning at the machine.
