Veterans Day November 11, 2016

Desco got its start as a two-man operation in small warehouse in Brea, CA in 1979. Since that time we have grown to include six USA based factories, 2 locations in the UK,1 location in Japan and to over 300 employees and their families. We are grateful for the those in the Desco family and all the veterans that have served in the armed forces. To see a Power Point of some of Desco family members that have served and their stories please click HERE.

Normal operations will continue at all Desco Industries locations on November 11, 2016.  We thank all the veterans and their families.

Identify Sources of ESD at the Work Area with Static Field Meter: Measure – Control – Verify

Indicate surface voltage and polarity of objects.

Insulators must be identified at an ESD work area and must meet the guidelines in the ESDA’s ESD Control Program Handbook-ESD TR20.20.

Non-Process Essential Insulators
If items that can charge to 125 volts or more*, then one of the following will be used:

  • Remove the item from the EPA
  • Permanently secure, so that insulators that charge to > 125 volts are a minimum of 1″ from ESD susceptible items at all times (12″ from ESDS if can charge 2,000 volts or more)

Process Essential Insulators
If process essential non-conductors / insulators (i.e., circuit board materials, some device packages, and test fixtures) are used in the ESD Protected Area that can charge 125 volts* or more, then one of the following will be used:

Use the field meter to verify that the the charge generation ESD protective version products (binders, shop travelers, packaging, foam, chair covers, etc) are < ±125 volts (<±2,000 volts) and ionization test kit to verify the offset voltage (balance) and charge decay of ionization equipment.

* Static field meters are used to measure the charge generation of insulators and isolated / un-grounded conductors. Surface resistance meters are used to measure the Resistance point-to-point (Rtt) and resistance point-to-ground (Rtg).

Remember the time when Steve Wozniak taught us about ESD?

In 1985 Apple produced a service video that explained the importance of ESD control when servicing an Apple II. Steve Wozniak, a co-founder of Apple computers, was featured in the 26 minute video explaining the handling of ESD susceptible devices.  Other than the fact that ESD components are smaller and more sensitive than ever (see the ESDA Electrostatic Discharge (ESD) Technology Roadmap – Revised May 2016), the same principles laid out in the 1985 video hold true today.  Take a step back in time:

Labor Day Holiday – Closed on Monday September 5, 2016

The 38th Annual EOS/ESD Symposium

The 38th Annual EOS/ESD Symposium and Exhibits will be held at the Hyatt Regency Orange County, Garden Grove (Anaheim), CA.

Desco has been a part of the ESD Symposium for nearly 30 years. Desco employees have volunteered their time to be a part of the ESD Association’s standards meetings, working groups, and other functions at the annual symposium. Desco will also have a booth in the exhibits area again this year.

Dates – September 11 – September 16, 2016 with Exhibits opened from Monday, September 12th at 6:00 p.m. closing Wednesday, September 14th at 1:10 p.m.

Contact us for a Complimentary Pass to the exhibits area or Register Online.

ESD to Blame for Sinking of Astronaut Grissom’s Spacecraft

Charles Murray, Technical Editor of Design News writes “Even casual observers of US space history know the unfortunate story of Gus Grissom. He’s the astronaut who accidently blew the hatch off the Liberty Bell 7 spacecraft, causing it to fill with seawater and sink into the depths of the Atlantic Ocean in 1961.”

Grissom maintained he did not panic and blow the hatch, though a cloud of doubt always hung above his claim. (It certainly was evident in the movie “The Right Stuff”).

Well, new evidence suggests that the real culprit was in fact electrostatic discharge, or ESD.

Wrist Straps Q and A – Part 1

Q: What is a wrist strap?

A: A wrist strap is the combination of a wrist band and a cord (usually coiled) that is used to ground an operator that handles ESD susceptible devices.09070

Q: Metal wrist straps last many times longer than fabric. I know it is dependent on conditions, but what is an average life expectancy of both in your best judgement?

A: Fabric: Under normal conditions, we expect the clasp portion of a fabric band to last forever – a lifetime. The band material can be replaced or washed as needed.


Metal: 3 years–5 years, but we rarely see one of the these that has failed due to normal use. The bands are designed with a series of springs and those springs can break if over-stretched, but that is about the only wear point on a metal band. See a video on how the metal bands are made HERE

Q: Do cords break/wear out faster than the wrist straps?

A: Yes. the cord will be subject to far more wear than a wrist band in most applications.


Q: Can I buy new cords or bands separately?

A: Yes. Customers also find that they need a different style cord (length, material, banana angle) or band (metal, fabric, color) after their initial purchase.


Q: Are ALL fabric wrist straps considered to be elastic?

A: Desco’s are, but no, not ALL fabric wrist straps are elastic.  Desco uses 36 strands of lycra spandex in the fabric to maintain contact with the wearer skin throughout normal motions. Some low quality wrist strap bands have minimal or no elastic fibers in them and only rely on a “tight cinch” of the band to maintain contact with the wearer’s skin. These types of bands are subject to intermittencies because the “tight cinch” is uncomfortable for the wearer and will loosen during normal (un-normal) movements by the operator.

Q:  When looking at all that is available, why the big disparity in wrist strap pricing with yours and your competitors?

A: The disparity in price is largely based on the quality of the raw materials and workmanship in manufacturing Desco wrist straps.  Some differentiating features are:

  • 300 series stainless steel machined snaps on wrist band
  • Silver plated polypropylene yarn used in band material
  • Lycra spandex elastic
  • 300 series stainless steel used on metal clasp parts
  • Replaceable band
  • Patented barrel type banana plug with machined contour spring support.
  • Cord bending Life Test average >1,000,000 cycles
  • Cord break load average 30 pounds.
  • T-2940 tinsel conductor and 7 strands of polyester wrapped with copper for flexibility and strength.
  • Date coded
  • UL Listed
  • Made in Chino, CA USA

 Q: Is anyone’s quality really that much better?

A: Yes.  Anybody that moves to continuous monitor system or an ESD Protected Area access control system that does not allow an operator into the ESD Protected Area or to continue working in the ESD Protected Area realizes that there is a massive difference in the quality. Quality assurance departments that track performance of wrist straps quickly realize that putting the product that they are handling at risk in favor of an ill-functioning wrist strap is not worth it.
