Temperature cycling is similar to temperature shock testing, with the difference being that temperature cycling has slower transitions between temperature extremes. Two chambers were acquired; the larger unit is appropriate for cycling printed circuit board assemblies while the small unit is appropriate for individual devices. Both chambers provide standards-compliant conditions for air-to-air testing.
Highly Accelerated Stress Test (HAST) Chamber (vendor: ESPEC, model EHS-211M)
HAST exposes assemblies to 85% relative humidity at 100 °C, at up to 4 atm pressure. This drives moisture into organic packaging structures and triggers ionic corrosion.
Scanning CCD camera designed to create high quality images of 2-D DIGE gels. It’s high resolution and precise motion control, produces accurate multichannel images of Cy2-, Cy3, and Cy5-labeled gels. The system is also designed to image other fluorescent gel applications, and can be used with ECL Plex Western Blotting System. It is controlled from the Ettan DIGE Imager software, and can be set up for a variety of gel formats.
This "drop tester" imposes shock impulses of controlled amplitude and duration. Peak values can be as high as 100,000 g, with durations as short as 0.05 ms. A typical test condition for drop testing of electronic assemblies is a half-sine impulse of 1500 g for 0.5 ms. The machine provides continuity monitoring at nanosecond resolution in accordance with testing standards and industry practices. A smaller, Research Ops-built drop tower is also available.
