Ground Master Equipment

Ground Monitors

3M Ground Master Equipment Ground Monitors are designed to provide

continuous monitoring of proper ground connections of up to eight tools

and up to 16 tools in tandem with another Ground Master monitor. The

monitor shows which individual ground connection is being monitored

and its status. Ground Master also monitors EMI on each ground, to

assist in diagnostics of lockups and malfunctions.

Each ground connection has its own easily replaceable fuse to prevent

dangerous voltages from incorrect wiring propagating to other equipment.

Ground Master provides intelligent information to a facility monitoring

system with detailed status on each ground connection. 3M

Ground

Master RT provides relay closure and a logic signal to the tool so that

it can be shut down in case of ground failure. Contact 3M for the best

model for your applications.

Features

• ANSI/ESDA S20.20 compliant.

• Alarm threshold adjustable from 1–20 ohm.

• Each ground connection is protected by individual fuse in case of

incorrect wiring.

• EMI monitored on each ground.

• Output to data acquisition or facility monitoring system (depending

on model).

• Logic signal output to the tool shuts tool down if ground fails

(depending on model).

Ground Monitors for Tools

3M Ground Man Monitors allow users to continuously monitor up to

three connection points on tools. The monitors indicate whether each

individual ground connection being monitored is within specification

or has failed. Ideal applications include SMT pick-and-place tools, IC

handlers, wire bonders, die attach and other tools.

Ground impedance alarm levels can be set by the user to satisfy a broad

range of requirements and compliance with standards such as ANSI

6.1 and ANSI/ESDA S20.20. Adding additional reliability, the host tool is

provided a logic level signal to shut the tool down in case of ground failure.

Miniature and unobtrusive, the Ground Man Monitors are easy to install

and easy to connect.

Use 3M Ground Man Plus Monitor CTC334 to monitor all important

ground connections in the tool and an operator. This monitor adds wrist

strap monitoring to allow only properly grounded operators to work with

the sensitive devices.

Features

• ANSI/ESDA S20.20 compliant.

• Adjustable threshold alarm from 1–20 ohm.

• Logic signal out to the host tool.

• Complete tool coverage.
