Image Sensor Testing

Presto Engineering, San Jose, GA has developed a custom, computer-controlled testing solution that illuminates sections of CMOS image sensors wafers in turn. Integrating the results enables the whole wafer to be tested automatically for an array of large sensors or even sensors that are right up to the size of an entire 12-in. wafer. The Teradyne® IP750Ex based test solution provides a large (80 × 100 mm), uniform (±2 percent), high-intensity illumination field up to 10K Lux at a range of color temperatures. Built-in IR filtering prevents sensor damage.

Tamper-Free Inks

CTI (Chromatic Technologies Inc.), Colorado Springs, CO, has developed a technology designed to stop product tampering. The BlindSpotz™ technology uses a dual indicator to detect product tampering from heat and freezing. The Tamper Freeze and Tamper Heat inks show color and messaging when thieves use heat or cold to tamper with packages. The ink technologies are designed to protect documents, seals, tape, labels, or various packaging substrates. Tamper Freeze inks turn from clear to blue when exposed to temperatures below -10° C, while Tamper Heat turns from gray to orange (or gray to pink) if exposed to heat greater than 65° C.

Balance Enclosure Workstations

An enclosure workstation from Hemco, Independence, MO, is designed to locate on an island or peninsula location with access on two sides. The SSE is offered in 24, 36, and 48 in. widths to accommodate an analytical balance and other small scale lab processes. It is constructed of chemical resistant metal framing and ¼ in. thick clear acrylic side panels and viewing sash. Efficient air flow design with airfoil and bypass directs contaminates to baffled exhaust, thereby providing superior air flow and containment performance for user protection. The ergonomic sash is angled 15° for ease of viewing comfort with 8 in. reach in opening height.
