3M introduces the Wrist Strap and Ground Monitor 773, providing effective workstation monitoring in applications having two metal ground requirements.

The monitor is designed for makers of PCBs, defense/aerospace equipment, medical devices and hard disk drives. It grounds and monitors two operators and monitors two metal grounds.

Because it measures ground impedance in automated tools during operation, users can perform immediate corrective actions to improve production yields. Features include real-time communication and an audio alarm, allowing for shut down if impedance values exceed standards.

It is easy to install and inconspicuous on the production floor. The monitor’s measurements are ANSI/ESD S6.1 and ANSI/ESD S20.20 compliant.

SMSC introduces USB82640 and USB82660 integrated connectivity devices. The single-chip, 2-port USB 2.0 hub controllers are combined with memory card reader functionality.

Users can store and access navigation data and entertainment content directly on solid-state memory cards.

The USB82640 has two downstream USB 2.0 ports and a single Secure Digital/MultimediaCard or Sony MemoryStick memory card interface.

The USB82660 has a second Secure Digital card interface and operates up to an ambient temperature of 105° C. Users can access navigation data and entertainment content simultaneously when stored in memory card formats.
Additional features include: PortMap, allowing flexible port mapping and disable sequences; PortSwap, aligning signal traces directly to connectors; and PHYBoost, allowing programmable transceiver drive strength to help preserve signal integrity in complex system environments.

Huntsman Advanced Materials introduces Araldite EP100 A/B epoxy adhesive. The two-part, thixotropic paste has a 2:1 mix ratio and low viscosity for easy handling.

The epoxy comes in a dual-barrel cartridge mixing kit, providing a waste-free application, and the structural adhesive cures at temperatures ranging from ambient to 212° F.

It does not require autoclave cycling and is reported to have high lap shear and good peel strengths once cured. The epoxy can maintain more than 90% of its shear strength after exposure to aviation fuels and hydraulic fluids, as well as 25% to 30% of its physical properties at temperatures up to 300° F.
