The importance of static auditing

16 12 2011

Static auditing is a process which involves assessing a production facility’s overall electrical performance. The long-term 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 important that any threats to the performance of a machine are identified as quickly and as early as possible.

Any major issues 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 usually 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.

Seeking professional advice to help you implement static control apparatus prevents the need to get someone in to regularly check the electrical conduction. This can save you money and time in the process, something which any business regardless of its size will appreciate.

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.

The power of antistatic products

30 11 2011

It is a necessity to buy anti static products for many companies within the manufacturing industry, especially when your work is related to the field of electronics. Such products are significant in protecting both you and the electronic components from the so-called ‘static charge build-up.’

Such build-up of electric charge on the surface of an object, known as the static electricity, can damage electronic components beyond repair. This is the reason why this should not be taken for granted—hence, it is really important to grab the following anti static products;

Anti Static Mat: This product is particularly useful for reducing the chance of getting in contact with static. The anti static mat is put beneath the components or the person working on them. This is to ensure the safety for the electronics and to avoid static shocks, especially when surrounded by electronic devices.

Anti Static Bags: When you need to ship or move electronic components, such as memory sticks, hard drives and sound cards, the use of anti static bags is important. This anti static product is use to deflect the natural static electricity which are usually built up during the journey.

Anti Static Clothing: As its name implies, it is utilised to protect the person working on the electronic devices and the devices themselves from the static electrical charges.

Ankle and Heel Straps: These can also be used to help protect users from currents and allow accumulated charge to seep away from the body.

These items work in an equally intricate way, dissipating electrical charge to specially implanted floor tiles to increase protection. They are particularly good for anyone who needs to be mobile when working as it is preferable to avoid a grounding cable in this cable.

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.

Antistatic bags and axial fans – Two vital tools in the components manufacturing process

7 10 2011

Within the electronics manufacturing industry, the protection of complex and intricate components is one of the most important aspects of the whole process.

The use of both antistatic bags and axial fans is central to this process. So why are these products so important? How exactly do they work?

Antistatic Bags

An antistatic bag is an integral piece of equipment for any major electronics manufacturing company.

They are generally used for shipping electrical components which are prone to damage caused by things like electrostatic discharge.

That type of discharge is the sudden electric current that flows between two objects at different electrical potentials. It is dangerous as it could potentially cause damage to important electronic equipment.

The bags are usually plastic and will have distinctive colours to denote whether they are metallised film or polyethylene.

Due to the critical need for protection against mechanical and electrostatic damage, various layers of protection are employed within the bags.

Axial Fans

Axial fans consist of a rotating arrangement of blades which act on the air. Usually contained within a casing, the blades used force the air to move parallel to the shaft about which the blades rotate.

The name of this specific fan comes from its propensity to blow air along the fan, and they have many modern day applications.

Within the electronics industry specifically, they are used to for cooling certain items of equipment. This is a vital cog within the whole process of constructing and transporting electrical connectors for example.

The larger varieties of axial fans are seen in mechanisms such as wind tunnels. Smaller types can be used for all manner of electronics work.

Given the size of some wind tunnels, it gives you an idea of how large certain axial fans can actually be.

An antistatic guide to testing equipment

30 09 2011

The complete control of static within an electrical environment is critical in attempting to maintain a safe and controlled work space for the applications to function.

But how can we test the functionality of antistatic products? And why are they so important within the electronic manufacturing sector?

Crucial Testing Equipment

The 3M Surface Resistance Meter is a work-surface tester.  It measures conductive, dissipative and insulative repeatable measurements, and is popular for audit testing.

The 3M Eye Meter is another work-surface tester which allows workers to work under most conditions for extreme temperatures and even tight locations due to its compact size and durability.

The 3M Workstation Monitor Checker is similar, however it is specifically designed to verify the proper operation of a dual wrist strap, workstation and ground monitors. 

This device checks the monitors are in compliance with the facilities specifications by simulating the proper resistances and signals.

A Test Kit for Static Control Surfaces is also a popular product, as it contains all the components needed to make testing mats and other surfaces simple and accurate.

A wrist strap monitor is another cost-efficient device which workers who are surrounded by electrical equipment will often use. 

They are both compact and versatile, and can be mounted directly onto device handling equipment, testers and auto insertion equipment.

Challenger Components has a vast amount of experience in supplying the right anti-static control products to clients seeking static control solutions.

They provide workstation products, test and equipment, and anti-static packaging solutions. All such products are pivotal when handling electronic components.

Tips and hints on static training and auditing are also available to ensure that you have everything you need to protect against this potentially damaging issue.





Electrostatic Discharge Safety Requirements for Hydrogen Producers

22 09 2011

Researchers from SRI International, working in partnership with Sandia National Laboratories, have confirmed the mechanism that can cause hydrogen to ignite during particulate electrostatic discharge.  

In the rare event of an uncontrolled hydrogen release, even in the absence of a known ignition source, electrostatic discharge can be enough to trigger hydrogen to ignite.

Hydrogen is typically stored in a pressurized system into which particles can be introduced if the storage vessel or connections are contaminated, corroded, or not cleaned properly. During an accidental hydrogen release, particles can accumulate charge if they move quickly against a vessel’s wall.

The ignition happens when there is a sudden release of accumulated charge, and the discharged energy is more than required to ignite hydrogen in a hydrogen-air mixture.

Static control is therefore increasingly important if you operate in an industry where hydrogen is also stored, too.

Static electricity is, put simply, electricity at rest. Static electricity is caused when there is an imbalance between non-conductive insulators of electricity, such as plastics, becoming negatively or positively charged.

Copper does not gain or lose electrons, which is why it is ideal for the use of conducting electricity. Plastic on the other hand is generally a poor conductor so it is relatively easy for it to charge with friction or heat, for example.

Static control is the common term used for the implementation of measures to lessen the effects of static electricity. 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. Popular methods include removing or neutralizing static electricity via induction, as well as ensuring that all electrics and machinery used are well grounded to help lessen the risk of high electrical charges.

Static Protection

There are two basic rules for handling static sensitive components in the workplace. The first is to ensure that the handling of all static sensitive components is carried out within and Electro Static Discharge (ESD) Protective Area (EPA). Secondly, transportation of all static sensitive components should take place in a static shielding container.

For the right level of protection it is vitally important to make sure that both of these rules are followed. Static damage in the form of degraded or softened devices could be the weak link in your chain and reduce the effectiveness of your in-house measures.
