Readily Record Temp and Pressure
If you need to collect data in the chemical, water, and food industries, this trio of data loggers can help. Depending on whether you need to measure heat or pressure, the family includes a thermocouple data logger, pressure data logger, and a precision resistance temperature detector (RTD) temperature recorder — all with NIST traceable calibration.

Mix Boundary-scan and Functional Test
A series of intelligent tools are helping to combine structural boundary-scan test and functional cluster test. The system contains an automated test program generator (ATPG) with a software processor for performing pin-fault diagnostics (PFD). After test, the PFD performs automatic fault diagnostics at the pin level.

Three Ways to Drown in Data
Data is the key to understanding current issues, analyzing trends, and determining actionable results. In test and production, the right data can help you get better products to market faster. The low cost of memory, the need to quickly analyze and share data, and an IT inability to handle test data can create test problems.

Add Some Color to Your Vision
Do you know when to use color in machine vision inspection? There are many applications that require color, including automotive paint inspection, print inspection (quality/registration), pharmaceutical inspection (label verification), part presence and/or detection, PCB assembly (part presence, verification, and placement).

Signal Compression Delights and Drawbacks
Digital signal compression can cut test cost when using mixed signal automated test equipment (ATE). But this Test & Measurement article says it also has a less efficient coding downside. The author adds that designers can cut test costs and need not fear that compression will negatively affect measurement accuracy.

Impulse Winding/Surge Tester - 7720
Wayne Kerr Electronics
The 7720 Impulse Winding Tester uses a very high-voltage impulse to stimulate the device under test (DUT). It analyzes the decay waveform to detect changes in material, shorted and damaged windings and other errors, including long term decay of a winding. The component is not damaged during the analysis process. Read more.

Collaborate and Celebrate
Can one company successfully introduce a major new product on its own? Organizations like IBM, Palm, Infineon, Samsung, and a host of others believe in joint development of the technology and process required to bring new products to market. For example, a semiconductor company provides the memory parts requested by the original equipment manufacturer (OEM), and the PCB firm designs the board. All agree that expertise in materials, manufacturing/process engineering, and test engineering is needed for project success. This Manufacturing Business Technology article relates the experiences of several product rollouts.
