Keyence's ball grid array (BGA) checker, the LT-9000 uses laser displacement sensing technology to provide accurate surface scanning for semiconductor ball grid array (BGA) packages. The checker provides measurement resolution as high as 0.01 µm (0.0004 mil) with target images magnified by up to 85 times on the monitor, even on round shapes. With a reference distance of 0.20 inch (6 mm), the measuring range is 0.01 inch ±0.3 mm. The unit has a linearity of ±0.5 percent of full scale. The LT-9000 Series provides critical measurements for other semiconductor processes including checking the etching progress on the wafer by measuring the dicing groove depth. The unit can also measure the marking depth for dates, lot numbers, and other lased etched items to ensure good print quality.

COMBINATION TEMPERATURE SENSOR
Minco's air handling system sensor includes both a low temperature cut-out sensor (freeze stat) and an averaging resistance temperature sensor. Designed specifically for HVAC and building automation markets, the Chill-Out Combination Sensor is a solid-state design with the relay integral to the tubing. The unit senses freezing temperatures within any six-inch section along its length and provides an averaging function as well. Replacing gas capillary tubes and mechanical switches, the sensor installs either vertically or horizontally. The combination sensor eliminates the need for a separate relay outside the airflow system reducing installation time and effort. Standard models have a 41F set point with a single pole double throw (SPDT) relay and units can be ordered with custom trip points.

PROGRAMMABLE SIGNAL CONDITIONER
Texas Instruments designed its PGA309 specifically for bridge sensors. The programmable analog signal conditioner provides digital calibration for zero, span, zero drift, and span drift, and amplifies the sensor signal and sensor linearization errors with applied stress (pressure, strain, etc.). Using a one-wire digital serial interface or a two-wire industry-standard connection to perform the calibration, the calibration parameters are stored in external nonvolatile memory eliminating a manual trim operation. A 2×2 input multiplexer (mux), auto-zero programmable-gain instrumentation amplifier, linearization circuit, voltage reference, internal oscillator, control logic, and an output amplifier are all part of the all-analog signal path. The precision, low-drift, no 1/f noise Front-End Programmable gain amplifier and output amplifier combination provide an overall gain that can be adjusted from 2.7 to 1152 V/V.

From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
