Antistatic: Flooring, Mats, Chairs and Shoes

31 10 2011

Anybody working in the electronics manufacturing industry can easily become charged with static electricity, and it is important to control this in order to prevent it from transferring from one application to another which could damage them or cause them to work incorrectly. 

Antistatic flooring is typically used by workers who use electrical applications likely to be affected by discharged electricity. 

The static from the person involved is grounded in the mat due to its specific materials.

 

Chairs, Mats & Shoes

There can be some antistatic mats which not only act as static control; they also allow workers to stand comfortably for long periods of time.  These are termed ant-fatigue mats and can come with or without the static control features.

They are made with durable rubber, and ones created by 3M consist of a matrix of hollow cylinders that function like a spring when compressed.

There are also static-free chairs available on the market, which are designed to eliminate the problems caused by combining conductive materials.  These are manufactured with hooded static-free casters, and static-free fabric.

In addition to antistatic mats and antistatic chairs, there are also antistatic shoes available for workers working with static electricity.

ESD shoes are able to ground the electrostatic discharge from a person as long as they are worn on a semi-conductive floor.  The shoes discharge the static electricity stored in a human body through the floor in a more controlled way.

Static Auditing – A brief guide

16 09 2011

Static auditing is one of the most important aspects of electronics manufacturing, and is particularly vital for machines in places such as industrial factories.

Static auditing is a process which involves assessing a production facility’s overall electrical performance.

The ultimate aim of the process is to identify any faults in the system which could affect the electrical current, or required performance of the machines they are connected to.

It is vitally important that any threats to the performance of a machine are identified early on, as this can put a strain on other electrical currents and make the whole mechanism less efficient.

An auditor will check the system by looking primarily for static areas (where the electricity is at rest).

Static electricity

Static electricity is caused when there is an imbalance between non-conductive insulators of electricity, becoming negatively or positively charged. Static control introduces a number of measures to help prevent this.

Removing or neutralising static electricity is a common method of static control, as well as ensuring the electrics are well grounded so this acts as buffer.

Static electricity discharge can be highly dangerous in industries dealing with flammable substances.

If a small electrical spark occurred here then this has the potential to ignite explosives mixtures.

Static Auditing in the UK

Seeking professional advice to help you implement static control apparatus prevents the need to get someone in to regularly check the electrical conduction.

Challenger Components have technical personnel who provide training following a pre-audit assessment of their system.  

Alternatively, they can help implement new devices to passively safeguard the work space from electrostatic discharge – protecting the instruments, and the employees from a potentially dangerous outcome.

How to Build an Electrostatic Protective Area

3 12 2010

Looking to create an electrostatic protective area at your workplace? Follow these tips on how to set up one up properly and successful static control tips.

In any workplace where electrical equipment is in use, there is a risk of static electricity being created.

There are a number of active and passive ways in which companies can implement static control within the electronics industry.

Popular methods to implement static control include removing or neutralizing static electricity via induction, as well as ensuring that all electrics and machinery in use are well grounded. This will help lessen the risk of high electrical charges taking place.

In order to successfully reduce the risk of electrostatic discharge in the workplace, it is extremely important to create a protective workstation, known as an Electrostatic Protective Area (EPA). This is the area where components that could be electrically charged with static energy should be handled.

Key Things to Consider for an Electrostatic Protective Area

An Electrostatic Protective Area should consist of a bench mat or static dissipative bench top and wrist strap ground cord. Any material used for bench matting must be incapable of tribo-electric charge generation and also able to drain safely to earth any static charge from conductive items placed on the surface.

As far as possible all items currently on the work bench which are made of insulative materials such as plastics and nylons, should be removed or redesigned in conductive materials.

All ground cords should be fully insulated along their entire length and incorporate a one megohm resistor in series for operator safety; this is especially important where surface conductive mats are used.

The wristband that a user of the workstation needs to wear will also need to contain conductive elements throughout the entire 360 degrees so that constant contact with the wearer is maintained. Additionally, the wrist strap ground cord should be fully insulated wire throughout its entire length and contain a one-megohm resistor in series. The strap should be capable of snap disconnection at wrist.

Challenger Components technical personnel can provide training, provide pre-audit assessment of your system, or help you set up a new program for your facility so you can safeguard your workplace from electrostatic discharge.
