In our ever-changing high tech world, a company’s

reputation for providing dependable products of excellent

quality is the one constant. Attention to ﬁne detail is the key

to ensuring that a high tech company here today will be

enjoying the rewards of tomorrow. Among the many details

of meeting these demanding speciﬁcations is the control of

electrostatic discharge (ESD).

The High Cost of Static Discharge

Static is generated all around us through simple movements,

such as walking from one workstation to another, or pulling

tape from a dispenser. A static charge builds up, causing a

discharge, often called a static shock. Even a small

discharge can measure several hundred volts and damage

microelectronic components, which can cause these

components to fail when installed in computers, cell phones

and other devices. Semi-conductor devices damaged by

static electricity can impact yield rates and product

reliability if not properly handled. However, more costly

than the damaged goods a company distributes is the

damaged reputation it suffers with its customer base. The

fact is most ESD damage can be prevented through a static

control program which emphasizes constant monitoring to

assure peak performance. To help achieve that goal of

constant vigilance, 3M is pleased to announce the

development of the 3M

790 Static Monitor

Model 790 Static Monitor.

Cost-effective Static Monitor

3M recognizes that while high tech companies have to act

quickly and wisely in their endeavor to establish a plan for

constant monitoring, they must do so with an eye toward the

bottom line. The 790 Monitor is a cost efﬁcient unit that is

small, compact and versatile in its usage, and may be

mounted directly onto device handling equipment, testers,

and auto insertion equipment. An operator simply inserts a

dual conductor ground cord into one of the input jacks

located on the monitor while working on an integrated

circuit device handler. The 790 may also be mounted at

individual workstations, and at auto insertion equipment

used in contract manufacturing facilities.

measuring the voltage potential on a person referenced to

earth ground. The 790 uses a slide switch allowing the user

to select the voltage level necessary for the speciﬁc job

function being performed. For example, the 1V and 3V

levels are used for highly critical applications in disk drive

and wafer fabrication manufacturing, while the 6V and 9V

levels can be used for less sensitive work areas such as PCB

assembly. Included with the 790 is a mounting plate that

allows it to be permanently mounted at an ESD workstation

or directly to a device handler, tester, or auto insertion

equipment. Power is supplied to the 790 through an AC

adapter.

front, which allows two operators to use one 790 monitor

unit at a workstation simultaneously. A green light indicates

that the unit is “on” and that all monitored connections are

within set limits. Two red lights and an audible alarm ﬂash

and beep at different rates to indicate 3 separate alarm

conditions:

• Exceeding voltage level set limit

• Loss of contact between arm and wristband

• 790 disconnected from ground

operator and the type of fault condition. The audible alarm

can be adjusted to a low or high level to overcome

background noise from other equipment that may be in use

in the area. Ring terminals on the end of the 790’s ground

and chassis cords provide a permanent connection.
