Treston furniture (ESD)
In ordinary movement a person creates static electricity. In these
circumstances hand contact with a conductive material will discharge
static from the body very rapidly. This is ESD = Electro Static Discharge.
Static electricity has become a major problem in the electronics industry.
Usually this passes unnoticed because our bodies do not feel discharges
below 3000 volts. We may see ESD above 5000 volts as a spark. The
most sensitive components may be damaged by a charge of just 30 volts,
and many standard components are sensitive to charges of between
100...200 volts. The presence of inherent ESD is not easy to detect.
Product damage may go undetected at the production stage, but lead
to failure at a later date. Once the potential dangers of ESD damage
are understood, effective methods of prevention can be put in place. Allinclusive protection from electrostatic discharges is a necessity whenever
modern electronic devices are handled. An EPA (ESD Protected Area)
should always use ESD protected materials to prevent component
damage. Protection should systematically extend from goods inwards
areas to fi nal test and packaging. A systematic approach to controlling
static in the workplace should include the following;
• ESD protected workstation, transport, storage systems
• ESD protected production tools and instruments
• ESD protected work clothes, shoes, wrist straps
• education of personnel, instructions, quality control
• cleanliness is important as dust acts as an isolator
• audits to ensure continuous ESD protection
