Creating an ESD Floor is as easy as 1, 2, 3

Implementing and improving ESD protection is an ongoing process for many companies. Selecting the correct ESD flooring is critical. However, maintaining that floor can be costly.

Statguard® Floor Care System

1. Statguard® Stripper

Unlocks our ESD polymers with the least amount of labour while minimising the pH level needed to rinse and neutralise. The Statguard® Stripper can save one or two labour rinse steps which cuts down labour time and can save you money. Typically 80% of the cost of maintaining a tile floor is labour. Cutting down the labour time is a savings to both the Building Service Contractor and the Customer.

2. Statguard® Neutraliser

Saves rinse steps to bring your stripped floor to the correct pH level before you apply our Statguard® Dissipative Floor Finish. Again, saving steps is saving time and cost. Reaching the correct pH level ensures the proper hardening of our finish and will help extend the life of the floor.

3. Statguard® Dissipative Floor Finish

Exceeds the required limits of EN 61340-5-1 for Resistance (operator grounding) of <1.0 x 109 ohms when tested per IEC 61340-4-1 and Operator Charge Generation of < 100 volts when tested per IEC 61340-4-1 when proper ESD footwear is used.

When Do You Need ionisation?

The primary function of an ioniser is to neutralise electrostatic charges on insulators and isolated (nongrounded) conductors to reduce the magnitude of electrostatic discharges in the ESD protected area.

ionisationOccasionally we are asked “how do you ground an insulator?” Since an insulator is a non…conductor, by definition, it cannot be grounded. What ESD control process is used to deal with insulators? The answer is ionisers or neutralisation. 

 

The primary function of an ioniser is to neutralise electrostatic charges on insulators and isolated (nongrounded) conductors to reduce the magnitude of electrostatic discharges in the ESD protected area. Point-of-use compressed gas ionisers combat electrostatic attraction (ESA) neutralising charges on particles that otherwise cause contamination or visual defects on products.

A common example of insulators and isolated conductors is a populated circuit board where the board is a process essential insulator and often components on the board are isolated (non-grounded) conductors. Most companies handling electronics have such sub-assemblies in their products.

The primary function of ionizers with regard to ESDS items are:

  • To remove / neutralize charges from process necessary insulators, which can charge ESDS items, thus creating the potential for a damaging CDM [Charged Device Model] event
  • Remember that the PCB substrate is a process necessary insulator and can become charged during automated handling processes
  • To remove / neutralize charges from a charged, isolated/floating conductor, which, when grounded can result in a potentially damaging CDM event
  • Remember that during automated handling processes, the ESDS devices on the PCB are isolated or floating conductors

5 Tips for Using Static Shielding Bags

5 Tips for using your Static Shielding Bags safely & effectively.

Picture41.Enclose product

Shielding bags should be large enough to enclose the entire product and closed with a label, tape or zipper-style bag. Determine the correct size bag for your application.

Picture52. Remove charges

Place closed bag on an ESD working surface before removing the product. This will remove any charge that might have accumulated on the surface of the bag.

 

Picture63. Don’t overuse

Re-using shielding bags is acceptable as long as there is no damage to the shielding layer. Bags with holes, tears or excessive wrinkles should be discarded.

 

Picture14. Not a working surface

Do not use a shielding bag as an ESD working surface. Although a shielding bag is safe to use around ESD susceptible products, it is not intended to be a working surface for product.

 

Picture25. No “potholders” or “glove”

Do not use a shielding bag as an “ESD potholder” or “ESD glove”.
This type of use offers no ESD protection to the product.

How do I protect my electronic devices from moisture?

Certain kinds of electronic devices called “Surface Mount Devices” or SMD’s are mounted on a circuit card by high temperature soldering. The body of the SMD is made from plastic that absorbs moisture from the air. When the case is heated during soldering, the moisture inside turns to steam and may break the device as the steam escapes. Keeping SMD’s dry before soldering means that the devices will not be damaged.

To protect your electronic devices protected from moisture, use moisture barrier bags with desiccant.

HOW TO USE DESICCANTS WITH MOISTURE BARRIER BAGS?

Desiccant is a drying agent that is used to absorb moisture from the air inside moisture barrier bags. Desiccant absorbs moisture vapor (humidity) from the air left inside that barrier bag after it has been sealed. Any moisture that penetrates the bag will also be absorbed. Desiccant remains dry to the touch even when it is fully saturated with moisture vapor.

HOW IS DESICCANT PURCHASED?

Desiccant is sold by the “Unit” or fractional Unit. One unit of desiccant will absorb a specific amount of moisture. A unit weighs about 28 grams or 1 ounce. The pouches of desiccant are placed into metal pails to keep the desiccant dry during shipping and storage.

HOW IS DESICCANT PACKAGED?

Desiccant is packaged in small sealed pouches made from a white plastic called “Tyvek”, or brown “Kraft” paper. Tyvek pouches are very clean and sulfur free. Kraft pouches are economical.

Inelco Hunter Ltd offer a range of moisture barrier bags, desiccant and humidity indicator cards to protect your devices

Why a static audit is vital for your production facility?

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.

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.

Inelco Hunter Ltd can provide a full assessment of your facility and recommend devices to passively safeguard the work space from electrostatic discharge – protecting the instruments, and the employees from a potentially dangerous outcome.
