MK26 vibration isolation workstation is designed for ultra-low natural frequency applications. It uses Minus K patented negative-stiffness vibration isolators to provide a compact, passive workstation with ultra-low natural frequencies, high internal structural frequencies and vertical and horizontal isolation efficiencies. 

Minus K vertical isolator uses a stiff spring and a negative-stiffness mechanism to achieve a low net vertical stiffness without affecting the static load supporting capability. Horizontal isolation is provided by beam columns connected in series with the vertical-motion isolator. Adjusted to a .5 Hz natural frequency, the workstation achieves 93% isolation efficiency at 2 Hz, 99% at 5 Hz, and 99.7% at 10 Hz. 

Can be configured for a variety of applications where disturbances due to external vibrations can adversely affect the operation of sensitive equipment. Customization options include guard rails, padded armrests, overhead equipment shelves, monitor stands, non-isolated shelves for supporting equipment off the tabletop, oversized keyboard shelves, retractable casters, Faraday Cages to protect sensitive operations from electromagnetic interference, tabletop enclosures to protect against harsh manufacturing environments and electrical accessories such as outlet strips for lighting.

Cookson Electronics’ ALPHA OM-338 Series solder pastes can enable a smooth transition to lead-free SMT assembly. Customers say this Pb-free solder paste can print as well or better than current Pb-bearing technology. It is said to deliver consistently uniform print deposit volume, thus overcoming print deposit volume variability. It also performs well in challenging applications where paste volume variability increases as print feature sizes become smaller. 

“The limiting factor in solder paste printability is the ratio of aperture wall area to the area of the aperture opening. When solder paste has more affinity for the walls of the stencil aperture than the pad being printed, you have a significant print failure mechanism,” said Mitch Holtzer, Global Products Manager for solder paste.  “ALPHA OM-338 Series has low print volume variability with .3 mm circles and .45 mm pitch qfp pads using 125 mil stencils, even with print speeds of 200 mm/sec. That performance can be reached using type 3 solder powder.”

Microscan, an ISO 9000:2000 certified company, attained ISO/IEC 15426-2 certification on its Quadrus Verifier, helping the estimated 40,000 U.S. Dept. of Defense (DoD) suppliers now required to verify Data Matrix symbols applied to parts and components.
 
Quadrus Verifier analyzes, measures and reports the quality of a Data Matrix symbol against the symbol quality criteria established in ISO/IEC 15415 and AS9132 standards, as specified in the government regulation MIL STD 130M. Provides accurate measurements and grades.
 
Quality Data Matrix symbols are an integral component of the DoD’s Item Unique Identification (IUID) initiative. The DoD has made it mandatory for contractors to provide a permanent Data Matrix Unique Item Identifier (UII) on nearly all items supplied to the DoD. The UII, which must remain affixed and readable for the life of the part, regardless of how long that may be, will provide visibility across various DoD information systems. The military will read the UII for asset management, inventory control, to access maintenance information and for other activities.
 
The product helps to eliminate inferior Data Matrix symbols. The fully-enclosed illumination chamber is engineered to produce the illumination and optics required by ISO/IEC 15415 to verify the quality of
Data Matrix symbols. The compact, lightweight verifier requires no onsite adjustments of optics or lighting and proves exceptionally easy to use.
 

Keithley Instruments announces two new additions to its Series 2600 System SourceMeter instruments. Models 2611 and 2612 add higher voltage and higher current capabilities to the source-measure unit (SMU) platform. The 200V and 10A capabilities of the two new models make them ideal for functional test and I-V characterization of silicon and compound semiconductor devices like FETs, diodes, voltage regulators and optoelectronic components. Combine high throughput SMU technology with a compact, scalable form factor that allows integration into systems from one to 16 SMU channels.
 
Designed to rapidly test low to medium pin count devices or multiple devices in a production test fixture. Model 2611 is a single-channel SMU, and the Model 2612 is a dual-channel unit. Multiple units can be integrated with an embedded Test Script Processor (TSP) and TSP-Link. Users cam execute high-speed, automated test sequences across multiple channels, independent of a PC operating system and its associated communication delays. This allows test speeds up to ten times faster than conventional test instruments. With two channels and a 200V source range, Model 2612 is capable of 400V differential operation, and each SMU channel is capable of 1.5A DC and 10A pulsed output. Both models have a new contact check feature that eliminates false failures in high-speed test applications by ensuring that all connections to the devices under test are intact before a source-measure sequence is initiated.

S300 diamond blade depaneling saw singulates assembled PCBs. Saw blade is a 2.95" diameter, .021" thick cutting blade.
 
Provides a stress-free method to singulate panels with sensitive surface-mount components close to the edge of the parting section, leaves a smooth edge finish with minimal stress  imparted to the PCB. Can also be used to singulate PCBs without scorelines, or to singulate PCBs with overhanging components on the parting line. Since the cutting depth can be set to just cut through the PCB itself, any components which overhang the parting line will remain intact. The working area of the saws are covered by a plexiglass enclosures.
 
The automatic, microprocessor-controlled, multiple-blade saw can be used for singulating side handling strips from DC/DC  converters or SIMM cards. An operator places up to five panels at one time into the input tray of the xy table. Pushing the start button activates the microprocessor-controlled process to bring the PCB past the saw blades to the offload position.  Up to eight blades can be set on a mandrell to cut multiple panels in one pass.
