Should I Wear ESD Socks?

The Need For ESD Socks

The combination of ESD flooring and footwear can be an effective way to ground personnel to control electrostatic discharges when using a wrist strap is not practical. For this system to be effective, the ESD flooring and footwear must have a low enough resistance to allow the voltage from the operator to flow to ground. There also must be a good contact between the person and the ESD footwear.

While ESD shoes may be made with conductive materials, they require a layer of perspiration in the sock to provide a path-to-ground. This is a concern because there are many variables between people. Per ESD Handbook TR20.20 section Common Testing Problems “Occasionally, footwear may indicate a high resistance… [A contributor being] heavy or insulative socks, or the absence of a sweat layer due to differences in temperature between the inner surfaces of the shoes and the wearer’s feet.”

wasting-timeYou may see inconsistent resistance measurements from person to person, especially during colder months when employees wear heavier socks and sweat less. One person may fail a test at the start of a shift, and pass ten minutes later after a sweat layer is formed.

How much time is wasted waiting for shoes to pass a test?
Or worse, how many sensitive items does a person come into contact with before their ESD shoes are truly acting as a path-to-ground?

Eliminate these variables and ensure a consistent path-to-ground with conductive ESD socks from Transforming Technologies. ESD socks are made with conductive yarn which provides a reliable electrical path from the start and rely less on the wearer’s skin resistance for repeatable performance regardless of the environment.

Single Wire Constant Monitors vs. Dual Wire Constant Monitors


This week’s ESD Q&A question comes from StaticCare reader Gina, she asks:

Question: What would be the the advantages or disadvantages of using a single wire or dual wire monitor?


Hello Gina,

This is a good question.

Single wire monitors work on capacitance or inductance and use single wire wrist straps.  They send a signal


The CM410 is a One Operator and Bench Single Wire Continuous Monitor.

down the wire to the wrist strap and expects to encounter some capacitance (approximately that of a person).  If there is a mass indicated at the end of the coil cord, the monitor assumes that the person is connected.

These systems work okay, but they can be fooled.  Some people have dry skin and do not make good contact with the wrist strap.  The single wire monitors are not able to detect if the person is actually electrically connected.

Dual wire monitors are resistance based and they use dual wire wrist straps.  They send a voltage up one wire and expect to receive a signal back from the second wire.   The wrist strap is divided and it relies on the operator’s skin to close the loop.   When this happens you can be assured that the operator is connected and that voltage is being drained through the wrist strap.   If the operator’s skin is dry and does not allow for the current to flow from one side of the strap to the other, the alarm will sound.


CM1602 is a One Operator and Bench Dual Wire Continuous Monitor

Dual wire monitoring is the only true wrist strap monitoring technology available. Single wire systems simply detect that a person is wearing a wrist strap and put the monitor into an unalarmed state. Resistance monitors actually measure the resistance of the wrist strap in combination with the person and alarm if the product exceeds preset levels. This accurate measurement ensures reliability.

The Need For ESD Safe Microscope Covers

Microscopes are a common instrument found in electronic assembly operations.  Microscopes are used for inspection and for assembly of very small objects.   It is critical that the microscope lenses remain clear and free of dust and other contamination.   When not in use, microscopes should be covered to protect the optics.

Some manufactures of microscopes provide covers for the time when the scopes are not in use.  Typically the covers are made of vinyl.  While vinyl may provide good protection from dust and fumes, it is a significant static generator.

The vinyl cover in the photo above shows an electrostatic voltage of -5,500 volts.   Once the cover is removed from the scope the voltage jumps even higher to -12,000 volts.

esd microscope1

ANSI/ESD S2020, the industry standard for ESD control programs, states that all nonessential insulators should be removed from the ESD protected area.

Since it is critical that microscopes be covered when not in use, it could be argued that the microscope cover is a process essential insulator.  ANSI/ESD S2020, Section 8.3.1 states that the ESD control program “shall include a plan for handling process required insulators in order to mitigate field induced CDM damage.”

The standard goes on to say that if the field is greater than 2000 volts/inch it must be kept more than 12” from the ESD sensitive item.   If the microscope is not in use, but work on ESD sensitive devices is being performed at the station, the vinyl scope cover becomes a significant risk.   The vinyl cover becomes even a greater risk if it is removed while there are ESD sensitive items at the workstation.

The best solution is to replace the vinyl cover with a microscope cover that is ESD safe, such as the Transforming Technologies MC1221W.   This scope cover is constructed of ESD safe material and does not generate a significant charge.

Even when the cover is removed, the charge remains very low.

With Transforming Technologies’ MC1221W you can protect your microscope optics from contamination while keeping your work station ESD safe.

Remove static from a balance or scale

Static electricity can have a negative impact on your measurements when using a scale or balance. Static electricity can cause several measurement issues: values may fluctuate or gradually change; repeatably of measurements is poor; or values may be stable but inaccurate.  Static electricity is essentially an electrical charge at rest or an electrical charge that accumulates on an object when it is rubbed against another object producing friction. Static can be removed, or “discharged” with an ionizer.


The Staticmaster 2U500 Ionizing Cartridge is the only self powered stat

ic eliminator available today. The small device requires no airflow, makes it an ideal solution for in-balance ionization. The 2U500 is inherently balanced to zero volts – which helps ensure thorough static removal for accurate weighs every time.

Significantly enhances the static eliminating power of the 2U500 Ionizing cartridge. Extensive testing has shown that adding the Grounding Kit to your in-balance ionizer can significantly increase the performance of the static eliminator. An indispensable accessory for mounting a 2U500 cartridge in the Balance Chamber. Simply remove the protective layer of the double-sided tape and affix the E-Z Mount to the back wall of the chamber. Once the mount is attached, replacing the 2U500 Ionizing Cartridge is fast and easy.

Transforming Technologies is proud to announce the addition of the IN4000PE Flexible Neck Ionizing Nozzle to our line of ESD Products.

Ptec™ Hands Free IonizationIN4000PE ionizing nozzle
The IN4000PE flexible nozzle neck frees the operator’s hands during assembly and manufacturing processes. A photoelectric eye controls both ionization and airflow, which reduces compressed air costs and extends the life  of the ionizer. The model IN4000PE ionizing air nozzle produces a 68KHz AC output of approximately 2200V and a continuous stream of balanced air ions.

Maintenance Savings
Ptec™ ionizers save time and money because they require no calibration. Emitter life is increased and maintenance frequency is reduced, due to
68KHz AC ion emission.
Ptec™ Ionization
The IN4000PE features the inherently stable output of all Ptec™ Ionizers and high frequency AC (68KHz) ion emis-sion. The flexible metal neck, with multiple nozzle options allows for easy operation and service of emitters. A photoelectric eye and .01 micron filter combine to deliver clean air at the correct pressure when needed.
