Latex Gloves – Are You Allergic?


Many industrial manufacturing environments require workers to wear protective gloves, including during electronics and medical device production and assembly. Latex gloves not only protect workers from harmful chemicals but also protect products from worker contact and contamination during manufacturing Read more

What to Consider When Choosing an Electro-Static Disapative (ESD) Mat

Choose your ESD mat with care

Like everything in manufacturing, the Electro-Static Disapative (ESD) mat, whatever type, continues to evolve to keep areas ESD-safe. Before you buy, think about what you really need to do the job. Mats come in all sizes and shapes and materials and can be expensive, depending on the application.

First the skinny on ESD mat types –

Conductive Mats (101 to 105 ohm) – low electrical resistance allowing ESD to flow across the surface. When grounded the ESD flows to ground and neutralizes the excess charge on the mat and worker.

Anti-Static Mats (105 to 1012 ohm) – higher electrical resistance than conductive mats and like conductive mats allow ESD to flow across the surface, however at a slower rate to prevent damage to microcircuit devices unable to tolerate a sudden flow of static charge from the device to a grounded mat.

Non-Conductive Mats (Insulator) (1012 ohm or higher) – prevent the flow of ESD across the surface. Generally used in high voltage environments where electrical charge movement of is undesirable and potentially life threatening.

 

CONSIDERATIONS –

  1. Rate of Neutralization– for work environments and many applications mats for neutralizing ESD range from 105 to 1011 ohm to efficiently address static. Dissipation of static electric charges will happen rapidly and at a controlled rate.
  2. Setting– Will the mat be used on carpet or hard surface like concrete? Mats can cause accidents, for instance, tripping if on carpet, or sliding if on concrete. Most rubber and vinyl conductive and anti-static mats will not wear well against chairs or carts. The wheels and weight will cause breakdown. Use ESD mats made to work on carpet or under chairs.
  3. CostA highpriced mat doesn’t mean it’s the right mat. For instance, more expensive ones like conductive mats could damage devices with microcircuits by reducing static charges too fast.
  4. Cleaning – Keep your mat clean and residue-free. Special static control cleaning solutions are available. Some mats can be dry-mopped or just swept.
  5. Life of Your Mat – If properly cared for, mats can last for years. Depending on your mat type, they can be self-healing and also very resistant to solder drips and spits.

Benefits

  • ESD mats protect sensitive equipment by drawing static electricity off workers before they touch susceptible objects. An ESD mat safely transfers static from a worker to the ground.
  • They’re generally cushy—so they help your back, your feet, everything that can begin to hurt after hours of standing up. Think anti-fatigue.

Note – Ungrounded conductive or anti-static mats hold an ESD charge and will transfer a charge to the next thing the mat touches.

Did you know?  The most significant invention to accelerate the electronics revolution happened in 1948 with the invention of the transistor. Next, in 1958 Jack Kirby invented the integrated circuit (Nobel Prize winner 2000) Half a year later Robert Noyce (and a co-founder of Intel) opened the door to smaller and more reliable, complex devices with the invention of the computer chip. Today, IC architectures can carry more than a billion transistors on a chip and soon may execute more than 4 trillion calculations per second. All this has led to less spacing between pin-outs of each chip and the transistors’ gates and junctions and, therefore the need for advanced ESD control. (more)


The Benefits of ESD-Safe Turntables -Take One for a Spin

Remember the lazy Susan?

imagesOnce a staple on every dining room table where with a spin of a wooden disc your salt and pepper shakers suddenly appeared in front of you. The same idea works for an ESD-safe turntable, however this disc does much more than turn.

Just like the revolving server, the turntable rotates to make working on large products and assemblies easier. With an ESD-safe turntable you avoid lifting heavy objects and–potential back injuries. With just a turn of the wheel you can access your next work area with ease—no lifting, lugging or jostling into place. And of course, the turntable eliminates electrostatic build-up.

The devices can be used on grounded or ungrounded surfaces, however on ungrounded surfaces the turntable must be grounded. The sizes range from 12” to 20” and come in different shapes depending on your application and preference.

ESD-Safe Turntable – Not for use with food. Great for heavy objects.

The ESD-safe turntable can be an invaluable tool in the electronics industry and has become a staple in its own right at many workstations. See a choice of ESD-safe turntables at All-Spec including these brands – Protektive Pak, Fancort, Sovella and Desco.

Summary –

  • Keeps heavy objects grounded and shielded from static
  • Eliminates heavy lifting or transport
  • Protects workers, products and components
  • Useful all kinds of heavy assembly, rework or maintenance jobs
  • Removes charges on contact with grounded ESD surfaces

Swedish Nurses Have Helped Develop Your Next Shoes

Posted on by Andy in Technical Articles Leave a comment

Nurses in a Swedish hospital a while back discovered what many of us know already — crocs™ are extremely comfortable to wear at work. Soon more and more were wearing them, but little did they know the rubberized soles could lead to a build-up of static.  When critical medical equipment suddenly failed 3 separate times, hospital administrators went looking for a reason.  They eventually traced the problem to the shoes and banned them from the facility.

The good news in all of this is it spurred crocs to develop the new ESD-safe version now stocked and available through All-Spec.  Now everyone in a cleanroom or static sensitive environment can enjoy all-day, on-the-job comfort.   Designed with a wide base, anatomically correct heel and medical arch support, you get a secure, stable fit.  The foam-based material absorbs shocks to your feet, knees, hips and lower back, significantly reducing fatigue.

Specifications:

  • Surface resistivity: 1×105 – 1×108
  • Cleanroom class 10,000 (ISO 4)
  • Material: Proprietary foam-based material
  • Colors: White or black
  • Men’s sizes: 3-13
  • Women’s sizes: 5-12
