Circuit board test fixture with electrostatic discharge (ESD) protection

The present invention in some embodiments provides for an apparatus comprised of a conductive strap and a lotion dispensing device connected to the conductive strap. The lotion dispensing device is comprised of a lotion storage device such as a reservoir, a permeable membrane, or a sponge. Preferably a person would put on the conductive strap and the lotion dispensing device in order to eliminate or reduce the transmission of static discharge to electronic circuitry and to minimize static discharge events that could interrupt the operation of electronic systems. The conductive strap includes a plurality of holes and the plurality of holes. The permeable membrane may be of a material, which dispenses lotion from the permeable membrane at a rate which is increased with heat. The size of holes in the conductive strap may increase in response to greater heat levels. The lotion dispensing device may be comprised of a reservoir filled with lotion. A grounding wire is preferably connected from the conductive strap to ground and preferably incorporates a resistance of about 1 mega-ohms. The conductive strap is preferably in the form of an elastic wrist band or watch band.

Wrist strap

The present invention provides a grounding system for discharging static electricity. The grounding system includes a body-contacting member which forms an electrical connection with at least a portion of a human body and a grounding cable. The grounding cable has an elongated conductive member with a first end for connection to ground potential and a second end for electrically communicating with the body-contacting member. At least one end of the elongated conductive member is embedded within a resistive material having an electrical conductivity of 10.sup.5 -10.sup.12 ohms/square. In one embodiment, the body-contacting member is a wrist or ankle strap while the resistive material is a polymer loaded with conductive and semiconductive particles. Exemplary conductive particles are selected from carbon, metals, and mixtures thereof.
