Introduction

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. Semiconductor devices damaged by static electricity can impact yield rates and product reliability if not properly handled. 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, Shinmark has developed the Single Wire Wrist Strap Monitor 880

Product Overview

The 880 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 wears the wrist strap on the monitor while working on the integrated circuit device handler.
Housed in metal box, the 880 works by measuring the voltage potential on a person referenced to the earth ground. It has two LEDs to indicate the monitored condition. A green light indicates that the unit is on and all monitored connections are okay. A red light and audible alarm flash and beep indicates the following conditions:
a. Loss of contact between arm and wristband
b. 880 disconnected from the earth ground
