SCS 770068 – WS Aware Dual-Wire Monitor with Big Brother Remotes and Ethernet

• Dual Workstation Continuous Monitor for operators, ESD worksurfaces, and metal tools
• Remote terminals with Big Brother sensor – detects operator, alarm if no wrist strap connected.
• Digital signal processing technology – small voltage applied when handling sensitive components.
• Ethernet connectivity – provide network communication with Static Management Program (SMP)

The SCS WS Aware Monitor is a dual workstation continuous monitor for operators, ESD worksurfaces, and metal tools. It continuously monitors the path-to-ground integrity and body voltage of two operators, as well as the path-to-ground integrity for two conductive or dissipative worksurfaces and two metal tools. It also continuously monitors for electromagnetic interference (EMI) on two metal tools which may cause electrical overstress (EOS) damage. The WS Aware Monitor eliminates the need for periodic testing and record-keeping of wrist straps.

The SCS WS Aware Monitor is designed with digital signal processing technology for true continuous monitoring (versus pulsed or intermittent) of wrist strap functionality (path-to-ground and presence of 1 megohm resistor) and operator safety according to accepted industry standards without capacitance variations from personnel or environment. Digital signal processing technology uses dual-wire wrist straps to apply an ultra-low test voltage of 0.05V onto the operator for the handling of sensitive components. The WS Aware Monitor features operator body voltage detection. It will alarm if the operator comes in contact with a voltage that would be dangerous to an ESD susceptible item. The WS Aware Monitor continuously monitors two metal tools for electromagnetic interference (EMI). EMI can cause equipment lockups and malfunction. The WS Aware Monitor will alarm if EMI is detected. Each WS Aware Monitor is calibrated with accepted procedures and standards traceable to the National Institute of Standards and Technology (NIST) and includes a certificate of calibration.

SCS WS Aware Dual-Wire Monitor with Remotes Features and Attributes:

• Dual workstation continuous monitor – monitors path-to-ground integrity of two operators, two conductive or dissipative worksurfaces, and two metal tools; meets ANSI/ESD S20.20 in accordance with ESD TR1.0-01-01
• SCS Power Relay (770069) compatibility – controls power to workbenches, hand tools, and other electronic devices dependent on the status of the WS Aware Monitor
• Ethernet connectivity – provides network communication with Static Management Program (SMP) – 770055 Sold Separately; Data collected includes operator resistance, operator voltage, mat resistance, metal tool impedance, and metal tool EMI voltage.
• Digital signal processing technology – Applies an ultra-low test voltage to the operator (0.05V) for the handling of sensitive components.
• Operator body voltage detection – alarms if the operator generates or contacts voltage that would be dangerous to an ESD susceptible item
• EMI monitoring – Alarms if the grounded metal tools have high-frequency noise that could cause electrical overstress (EOS) damage
• NIST calibrated with certificate included
• The system includes a monitor and two Big Brother remote terminals – the monitor can be installed at eye level, and remote terminals can be mounted at desired locations up to 10 feet away; each remote terminal includes a monitored jack for operators and an unmonitored jack for visitors
• Remote terminal with Big Brother sensor – Detects the presence of an operator and alarms if a wrist strap is not connected to prevent ungrounded handling of ESD susceptible items
• 100-240V AC power adapter with interchangeable plugs – Works with standard electrical systems in North America, the United Kingdom, Japan, Asia, and Europe
• Made in the USA

The SCS 770067 and 770068 WS Aware Monitors are compatible with SCS Static Management Program (SMP). SMP continuously monitors an ESD process control system throughout all stages of manufacturing. SMP captures data from SCS workstations, equipment, and ESD event continuous monitors and provides a real-time picture of critical manufacturing processes. All activity is stored in a database for ongoing quality control purposes. SMP allows its administrators to pinpoint areas of concern and prevent ESD events. Quantifiable data allows its administrators to see trends, become more proactive, and prove the efficiency of its ESD process control system.

“Compliance verification records shall be established and maintained to provide evidence of conformity to the technical requirements.”

“Daily (wrist strap system) testing may be omitted if constant monitoring is used.”

“Typical Test programs recommend that wrist straps that are used daily should be tested daily. However, if the products that are being produced are of such value that knowledge of a continuous, reliable ground is needed, and then continuous monitoring should be considered or even required.”
