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
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.
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.

EMIT installed our IRIS Room Ionization System at a customer over this past weekend. The room called for a 3 zone system covering approximately 10,000 square feet. The power supplies and components are built in our factory in Chino, CA leading up to the scheduled installation date with the customer.
An outline of the installation schedule was as follows:
Day 1 – Friday
Delivered all the materials. Staged all the bagged material in the staging room for the clean room.
Day 2 – Saturday
Hang the majority of the emitters, sensors, and cables. Mount the back plates for the tablets and power supplies.
Day 3 – Sunday
Connect system to IRIS power supplies and tablet monitoring systems.
Day 4 – Monday
Take initial performance measurements. Dial in the settings to find the “sweet spot” and get the targeted decay times we projected. By the end of the day we were getting decay times in three ranges depending on air flow – 16 to 32 seconds in good air flow, 50-60 seconds in fair airflow, and 75-85 seconds in poor airflow.
Day 5 – Tuesday
Finalize the performance measurements after being in operation for over 24 hours. Set up IRIS Server to communicate with the IRIS Client over the customer’s network.
About EMIT IRIS Room Ionization System
IRIS Room Ionization System neutralizes electrostatic charges in an entire cubic volume of a room atmosphere. Each IRIS power supplies can power and control 200 over-head mounted emitters covering approximately 3,500 square feet of area. Each emitter produces bi-polar ionization resulting in stable ion production when in use. Real time ion sensing and cycle timing allows for uninterrupted operation. Standard ABS components and a modular design allow the emitters to be configured to fit most pre-existing rooms. Pair with EMIT TEAM5 IRIS Client Software for continuous automatic ionization balancing of each zone, to keep a running log of all zone activities and to manage calibration.
All US based Desco Industries locations will be closed on Monday May 26, 2014 in observance of the Memorial Day Holiday. Customer service will be closed for the day and no orders will be processed for the day. Normal operations will resume on Tuesday May 27, 2014.
