ESD Process Control and Data Acquisition Solutions

Two important elements to managing an ESD Control Plan are:

  •  controlling access to the ESD Protected Area
  • and record keeping of personnel grounding devices – wrist strap, foot grounders, and smocks.

ESD coordinators are faced with the challenge of limiting access to the ESD Protected Area to people that are properly trained to handle ESD susceptible Paper Logsdevices and that are using a personnel grounding device.  Additionally, the ESD coordinator must track the people that have accessed the ESD Protected Area and confirm that their personnel grounding devices are functioning correctly.  Traditionally this has been done with a log book where operators (and visitors) note their test results in an honor system fashion.  These log books are then stored for future uses for reference in quality issues or audits.  The record keeping system is of a bygone era and is quickly being replaced with a more modern electronic record keeping system.

The SmartLog V5™ independently tests the resistance path limits of the wrist strap and both ESD footwear in less than 2 seconds. It may also test an ESD garment while worn if it is used as part of personnel grounding path. Test results are electronically stored in the SmartLog V5™ and then downloaded to a PC for evaluation and archiving of the data.  This product can be used as one of the tools to fulfill the ANSI/ESD S20.20 section 7.3 “Compliance Verification Plan.”  The Smartlog V5™ may be paired with a turnstile or connection to an electronically locking door to further control access to the ESD Protected Area. The TEAM5 software manages personnel and test data for personnel ESD grounding devices tested on the SmartLog V5™.

Test and personnel data may be SmartlogV5withTurnstileviewed/reported locally, via a network Web page and emailed automatically on a scheduled or on-demand basis. TEAM5 uses date/time stamps on all user requirement changes to comply with quality control and record keeping requirements. This ensures archived tests are always linked to historically accurate personnel data. The SmartLog V5™ ESD test stations and Network (Multi User) programs operate semi-autonomously to ensure continuous operation even while network or server outages occur.

Benefits of Right Angle Banana Coil Cords

Low ProfileRightAngle_vs_StraightBanana
The profile of a right angle banana plug when inserted in a banana jack is approximately 4 times less than a straight banana plug.  The lower profile reduces the opportunity for people, carts, or other things in the work area to accidentally disengage or damage the banana plug.

 

Reduced Strain on Cord
At most ESD protected workstations the banana jack or workstation monitor is located at the front edge to one side. The design of a right angle banana coil cord reduces the stress on the plug/jack connection.  Operators will experience less “tug” from the coil cord and the lifespan of the cord will be extended.

New ESD Dissipative Label Dispensing Box

Label Dispenser
The new 06767 Dissipative Label Dispenser holds a roll of labels and helps peel away the backing from the label. It is made of static dissipative corrugated and is designed to be used on a grounded ESD work surface at the workstation in an ESD Protected Area. This dispenser can be used with labels up to 2 inches wide. Label rolls must have a core to work with the label dispenser.

Labels are not included. Item ships unassembled. Download assembly instructions here.

Paper in the ESD Protected Area

We are regularly asked if paper is OK in the ESD Protected Area or at an ESD workstation.

Regular paper is insulative but tends to be low charging because it is hygroscopic (readily absorbs moisture).  The primary concern with paper is placing ESD sensitive items on the paper interfering with the path-to-ground of the grounded ESD mat.  Best practice is to use Dissipative Paper or have regular insulative paper in Dissipative Document Holders. If regular paper is used, discipline operators to not place any ESD sensitive items on the paper, and this should be followed particularly during periods of low relative humidity.

Although the ANSI/ESD S20.20-2014 does not mention paper specifically it says the following about insulators:

Section 8.3.1 Insulators
All nonessential insulators such as coffee cups, food wrappers and personal items shall be removed from the EPA.
The ESD program shall include a plan for handling process-required insulators in order to mitigate field-induced CDM damage.

If the field measured on the process required insulator is greater than 2000 volts/inch and the process required insulator is less than 30 cm (12 inches) from the ESDS item, steps shall be taken to either:
A) Separate the required insulator from the ESDS item by a distance of greater than 30 cm (12 inches); or
B) Use ionization or other charge mitigating techniques to neutralize the charge.

If the field measured on the process required insulator is greater than 125 volts/inch and the process required insulator is less than 2.5 cm (1 inch) from the ESDS item, steps shall be taken to either:
A) Separate the required insulator from the ESDS item by a distance of greater than 2.5 cm (1 inch); or
B) Use ionization or other charge mitigating techniques to neutralize the charge.

Also ESD Handbook ESD TR20.20 section 2.4 Sources of Static Electricity states:

It should be understood that any object, item, material or person could be a source of static electricity in the work environment. Removal of unnecessary nonconductors, replacing nonconductive materials with dissipative or conductive materials and grounding all conductors are the principle methods of controlling static electricity in the workplace, regardless of the activity.”

Wrist Strap Disintegration

On the EDN Network‘s “Rowe’s and Columns” blog, Martin Rowe’s recent post is about the disintegration of his wrist strap.

 I’ve used ESD wrist straps whenever I work on a computer and have never had an ESD problem, even in dry winter conditions. Today, I needed to open a desktop computer so I reached for one of my four ESD wrist straps. To my surprise, all of them had exposed ground wires. The insulation was gone in a few places. What happened?

The wrist strap pictured in the blog  is NOT a product made by Desco. To see pictures and the rest of the post go here

Desco has been making wrist straps  for over 30 years.   Our wrist straps are made at our Chino, CA facility.

The problem Martin is having is somewhat odd but is likely due to plasticizers leaching out (possibly accelerated with heat) of the PVC material over time which can cause the cord’s insulation to become brittle and break down. Desco makes some of our wrist straps with  polyurethane insulated coil cords to avoid this. An operator that is working near a heat source (soldering iron, oven, power supplies, etc) and using a coil cord with PVC insulation may experience something similar.

Desco’s wrist straps are some of the most reliable products on the market. We include manufacturer’s markings and date codes on the coil cord and the wristband to allow our customers to track the value of our product. Please contact us at Service@Desco.com if you are interested in evaluating a Desco wrist strap.

Controlling ESD on PCB and Component Labels

A typical ESD Control Plan covers a facility from receiving to shipping.  Within the facility, the established ESD Protected Area must account for all potential points where ESD may damage ESD susceptible devices.  A white paper from Brady Corporation covers controlling ESD on PCB and component labels.  The paper points out that:

One common area where ESD can be present that may be overlooked is in standard PCB and component labels used to track work in process and provide long-term records of production, repair and warranty information. Many people who are familiar with ESD and controlling ESD in the electronics assembly environment may not have considered standard labels as a potential source for ESD events that can damage electronic components or assemblies.
