3 790 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 efcient 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. Housed in static dissipative plastic, the 790 works by 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 specic 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. The 790 has two wrist strap input jacks located on its 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 ash and beep at different rates to indicate 3 separate alarm In our ever-changing high tech world, a companys conditions: reputation for providing dependable products of excellent Exceeding voltage level set limit quality is the one constant. Attention to ne detail is the key Loss of contact between arm and wristband to ensuring that a high tech company here today will be 790 disconnected from ground enjoying the rewards of tomorrow. Among the many details These distinct alarms make it easy to identify which of meeting these demanding specications is the control of operator and the type of fault condition. The audible alarm electrostatic discharge (ESD). can be adjusted to a low or high level to overcome background noise from other equipment that may be in use The High Cost of Static Discharge in the area. Ring terminals on the end of the 790s ground Static is generated all around us through simple movements, and chassis cords provide a permanent connection. such as walking from one workstation to another, or pulling tape from a dispenser. A static charge builds up, causing a Product Features discharge, often called a static shock. Even a small Audible and visible alarms discharge can measure several hundred volts and damage Compact system microelectronic components, which can cause these Pre-select test voltages 1V, 3V, 6V, & 9V components to fail when installed in computers, cell phones Static-dissipative plastic housing and other devices. Semi-conductor devices damaged by Mounts easily to ESD worksurface static electricity can impact yield rates and product Regulatory Compliance: UL & CE reliability if not properly handled. However, more costly The 3M 790 Static Monitor system includes a mounting than the damaged goods a company distributes is the plate with adhesive, an AC adapter, and two ground cords damaged reputation it suffers with its customer base. The with a two-wire connector. 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 Model 790 Static Monitor.TM 3M 790 Static Monitor Required accessories and optional parts for 3M 790 Static Monitor Model No. Description Size 2368VM Dual Conductor Fabric Wrist Band Adjustable 2381VM Dual Conductor Metal Wrist Strap* Small 2382 VM Dual Conductor Metal Wrist Strap* Medium 2383 VM Dual Conductor Metal Wrist Strap* Large 2384VM Dual Conductor Metal Wrist Band Small 2385VM Dual Conductor Metal Wrist Band Medium 2386VM Dual Conductor Metal Wrist Band Large 2360 Dual Conductor Coil Cord 5 ft. 2370 Dual Conductor Coil Cord 10 ft. 2371 Dual Conductor Coil Cord 20 ft. 3057 Stand-By Jack *Includes Band & Cord Quality in Action Ordering Information: ISO requirements state the need for verication of performance For ordering information, technical information and of all test equipment.
