5 common mistakes in ESD Control & how to avoid them

Desco Europe Blog

Many companies implement an ESD Control Programme with the aim of improving their operations. Effective ESD control can be a key to improving:

  • Productivity,
  • Quality and
  • Customer satisfaction.

However, problems arise when an organisation invests in ESD protective products and/or equipment and then misuses them. Not only do these companies waste a lot of money but they could also be causing more harm than good. So, with today’s blog post we want to highlight some of the major issues we have come across and how you can avoid or fix them.

Introduction

Remember that for a successful ESD Control Programme, ESD protection is required throughout the manufacturing process: from goods-in to assembly all the way through to inspection. Anybody who handles electrical or electronic parts, assemblies or equipment that are susceptible to damage by electrostatic discharges should take necessary precautions.

Think of viruses or bacteria that can infect the human…

Continuous Monitors and ESD Control

Desco Europe Blog

Most of you have probably heard of continuous monitors before but do you know:

  • what exactly they do or
  • why you should be using a continuous monitoring system?

If your response to one (or both) of the above questions is ‘no’, you’re lucky because we’ll be answering them here today. If you already know the answers, why not read on anyway? You never know: you might be learning something new…

What are continuous monitors?

When talking about wrist straps a couple of weeks ago, we mentioned the need for periodic testing. Every day before each use, wrist straps need to be checked (while worn) to ensure they ground the operator correctly.

So imagine this scenario: you come to work in the morning, you test your wrist strap, it passes and you get to working on your ESD sensitive devices. 3 hours later, when you come back from your tea break…

Advantages of Protektive Pak® Material

Charleswater Blog

Protektive Pak® Material is made from static dissipative impregnated corrugated material with a buried shielding layer – it provides static shielding to protect ESD sensitive items from ElectroStatic charges, and ElectroStatic Discharges [ESD].

Introduction to Protektive Pak® Material

So now you’re probably wondering what’s different about this type of material – loads of companies out there offer similar products, right? That’s true – BUT what makes Protektive Pak® Material so unique is that its ESD properties are manufactured into the liners of the material itself. Many other materials have a coating or paint applied that gives them their ESD properties. This in itself is not a problem. However, it becomes an issue if the outer layer of your ESD container is damaged.

Are antistatic and dissipative bags the same?

Follow us on TwitterView our profile on LinkedInYouTubeGooglePlus

Antistatic is an ESD control property properly referred to as “low charging”. This is an important property for all bags used inside or outside of an ESD protected area (EPA). Specifically, it is important that the inside of the bag is low charging. This ensures that when the ESD Sensitive Device is inserted into the bag or otherwise moves, there is minimum electrostatic charge generation.

Dissipative is the electrical property of resistance so when grounded electrostatic charges will be removed to ground. This is an important ESD control property as the bag can be grounded; being dissipative provides an electrical path for an electrostatic charge to dissipate from the bag.

All bags inside the ESD Protected Area [EPA] should be both low charging and dissipative whether packaging ESD sensitive item or non-ESD sensitive items.

Packaging Standard EN 61340-5-3 clause 5.3 Outside an EPA:
“Transportation of…

How to manage Charge Generation from Flooring

Desco Europe Blog

We’ve previously learned that the simple separation of two surfaces can cause a transfer of electrons resulting in one surface being positively and the other negatively charged. A person walking across a floor and soles contracting & separating from the floor is such an example. The resulting static charges that generate are an annoying and costly occurrence for office and factory employees. The thing is, they can easily be controlled with existing carpets and tiled floors. Learn how in today’s post.

What is Static Electricity?

Static electricity is an electrical charge that is at rest – as opposed to electricity in motion or current electricity. Static charges can be generated by either friction or induction. Typical examples are the Wimshurst machine that uses friction and the Van de Graaff generator using electrostatic induction.

How is Static Electricity generated?

The most common generation of static charge is the triboelectric charge or…

The Difference between ElectroStatic Charges & Electrostatic Discharges (ESD)

Desco Europe Blog

A question that comes up, again and again, is “Are ElectroStatic charges and ElectroStatic discharges different?” so we thought it’d be helpful for everyone to put together a blog post on the subject. So let’s get started:

ElectroStatic charges vs. ElectroStatic discharges

ElectroStatic charges and ElectroStatic discharges are different. All material can tribocharge (generate ElectroStatic charges). This is static electricity which is an electrical charge at rest. When an electrical charge is not at rest but discharges (i.e. ESD), problems can occur. All matter is constructed from atoms which have negatively charged electrons circling the atom’s nucleus which includes positively charged protons. The atom having an equal number of electrons and protons balances out having no charge.

Balanced AtomBalanced Atom with no Charge

Electrostatic charges are most commonly created by contact and separation; when two surfaces contact then separate, some atom electrons move from one surface to the other, causing an…

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
