A single static discharge you can’t even feel can destroy a modern microchip. The human threshold for sensing an electrostatic discharge is around 3,000 volts, but many electronic components fail at well under 100 volts. That gap — between what you can feel and what can kill a component — is exactly why ESD gloves exist, and why choosing the wrong pair is one of the most common weak points in an electronics manufacturing ESD control program.
ESD gloves sit at a busy intersection of requirements: they must bleed off static charge safely, protect the product from skin oils and particles, survive a full shift of handling work, and still let the wearer feel what they’re doing. This guide walks through how ESD gloves work, the types on the market, the specifications that actually matter, and how to match a glove to your EPA (electrostatic protected area) and your process.
Why Electronics Work Needs Dedicated ESD Gloves
Every time two materials touch and separate — a hand lifting a PCB off a tray, a sleeve brushing a workbench — charge transfers between them. This triboelectric charging is unavoidable, and in an electronics environment the consequences are measured in failed boards, latent defects, and warranty returns. The three standard ESD failure models tell the story: the human body model (HBM) covers discharges from a charged person through the hands; the charged device model (CDM) covers discharges from the component itself; the machine model (MM) covers equipment discharges. Gloves address the first model directly — the person touching the product.
A regular work glove makes the problem worse, not better. Standard nitrile, latex, or fabric gloves are insulators: they trap charge on their surface and can hold thousands of volts, then dump it into the first grounded conductor they touch — which might be the circuit board in your hand. ESD gloves are engineered the other way around. They provide a controlled, dissipative path that lets charge bleed away slowly instead of discharging in a single destructive spike, and they do it without requiring the wearer to think about it. As part of a complete ESD protective clothing program — garments, gloves, and grounded footwear working together — they close one of the last uncontrolled gaps between the operator and the product.
There is a second job ESD gloves do that gets less attention: contamination control. Bare hands deposit skin oils, salts, and moisture on contacts, connectors, and solder surfaces. In fine-pitch electronics work, that contamination causes solderability problems and long-term reliability failures. A good ESD glove is therefore doing double duty — static control and product cleanliness — and both functions degrade as the glove wears, which is why selection and replacement discipline matter.
The Main Types of ESD Gloves
ESD gloves fall into a few broad families, distinguished by how they achieve static dissipation and what level of dexterity and cleanliness they offer.
Carbon-loaded or carbon-thread knit gloves
The workhorse of electronics assembly. These are seamless knit gloves — usually nylon or polyester — with carbon fibers or carbon-loaded yarn woven through the fabric, often in a grid or striped pattern you can see on close inspection. The carbon provides a dissipative network across the whole glove. They are washable and reusable, breathable enough for all-day wear, and available in various thicknesses. The trade-off is particle shedding: knit fabrics release more fibers than coated gloves, so they are a poor choice for cleanroom classes where particle counts are tightly controlled.
Dissipative disposable gloves (ESD nitrile)
Single-use nitrile gloves formulated with dissipative additives. They look and feel much like standard examination nitrile but test within the dissipative resistance range. Their advantage is cleanliness and convenience: a fresh pair every task or every few hours, no laundering program to manage, minimal particle shedding. The downsides are cost per use at scale, fit consistency across brands, and the fact that dissipative performance can vary with humidity and with the wearer’s skin moisture. They are the default choice in cleanrooms and in medical-electronics crossover environments.
PU-coated ESD gloves
A knit liner (often with conductive fiber) coated on the palm and fingers with dissipative polyurethane. The coating improves grip enormously — important when handling smooth PCBs, small housings, or oily mechanical parts — and adds abrasion resistance that extends glove life. The coating is also relatively low-linting compared with an uncoated knit. The compromise is breathability: coated palms run warmer, and once the coating wears through in high-abrasion spots, both grip and ESD performance in that zone degrade.
Finger cots (ESD)
For tasks where full gloves kill too much dexterity — fine rework, microscope work, connector mating — dissipative finger cots cover just the fingertips. They are a compromise: better ESD protection than bare fingers, worse than a full glove, and they do nothing about charge on the rest of the hand. Use them as a targeted solution, not as a facility-wide default.
Specifications That Actually Matter
ESD glove datasheets can be a wall of numbers. Four specifications do most of the decision-making work.
Surface resistance (or surface resistivity)
This is the headline number. Per IEC 61340-5-1, the ESD control program standard, materials worn or used in an EPA generally need to fall in the dissipative range — surface resistance between 1 × 10^4 and 1 × 10^11 ohms, with the lower end preferred for items in direct contact with ESD-sensitive devices. Below 10^4 ohms a material is considered conductive: it drains charge fast, which sounds good until you realize a conductive glove touching a charged component can deliver the very fast, high-current discharge you’re trying to prevent. Above 10^11 ohms the material is insulative and has no business in an EPA. When a datasheet gives a single resistance value, check the test method and the humidity it was measured at — resistance climbs as air gets drier, and a glove that passes at 50% relative humidity may fail at 15%.
Charge decay time
Resistance tells you how easily charge moves; charge decay tells you how fast it actually leaves. The standard test charges the material to 1,000 volts and measures how long it takes to fall to 100 volts. For EPA use you generally want decay well under 2 seconds. A glove can have acceptable resistance but sluggish decay if its dissipative network is patchy — decay testing catches that.
Triboelectric charge generation
How much charge does the glove itself generate when rubbed against common materials? A glove that dissipates well but generates aggressively is fighting itself. Good ESD gloves are tested for low charge generation against reference materials. This matters most in low-humidity environments and in handling of unprotected boards.
Fit, dexterity, and tactility
The best-spec’d glove in the world is useless if operators take it off to do fine work. Gloves that are too thick, too loose at the fingertips, or too hot get removed — and every removal is an unprotected handling event. For precision electronics work, look for thin gauges (15-gauge knit or thinner), snug fingertip fit, and touchscreen-compatible fingertips if operators use tablets or test equipment interfaces. Run wear trials with actual operators before standardizing: a two-week trial with the people who will wear the gloves eight hours a day surfaces fit problems no datasheet will.
Matching the Glove to Your EPA
Not every electronics task needs the same glove. Map the glove to the sensitivity of what you’re handling and the controls already in your EPA.
- General PCB assembly (components rated 250V HBM and above): carbon-knit or dissipative PU-coated reusable gloves are the economical default. Pair with wrist straps or ESD footwear/flooring per your control plan.
- Handling of highly sensitive devices (below 100V HBM, CDM-sensitive parts): step up to low-linting dissipative disposables or PU-coated gloves with verified low charge generation, and verify the full person-plus-glove system resistance with the glove on — the glove is only one link in the ground path.
- Cleanroom electronics: dissipative disposable nitrile, changed on a defined schedule. Reusable knits generally can’t meet particle budgets.
- Rework and inspection: thin-gauge knit or ESD finger cots where dexterity is the binding constraint, accepting the trade-off consciously.
One critical point: a glove never replaces personnel grounding. IEC 61340-5-1 requires the person to be grounded — typically via a wrist strap or through ESD footwear and flooring — because a dissipative glove on an ungrounded person just makes the person a nicely dissipative capacitor. The glove controls charge at the contact point; the ground path removes it from the person. Verify the combination, not just the glove in isolation. In the United States, ANSI/ESD S20.20 is the equivalent facility-level ESD control program standard.
Laundering, Testing, and Replacement
Reusable ESD gloves are a managed asset, not a consumable you can forget about. Carbon fibers break with washing and wear; a glove that tested dissipative on day one can drift insulative after twenty industrial launderings. Build three disciplines into your program: launder per the manufacturer’s instructions (wrong detergents coat the conductive fibers and kill performance), test on a schedule (incoming inspection plus periodic re-verification of in-service gloves, typically with a surface resistance meter), and define a retirement rule — a maximum number of wash cycles or a fixed service life, whichever comes first. For disposables, the discipline is simpler but just as real: define the change interval by task, not by “when they look dirty,” because ESD performance is invisible.
Common Mistakes to Avoid
- Buying on price alone. The cheapest “ESD glove” on a marketplace listing often has no test data behind the claim. Ask for surface resistance test reports before you buy in volume.
- Assuming “anti-static” means EPA-ready. “Anti-static” is a marketing word with no defined threshold. “Dissipative per IEC 61340” is a testable claim. Insist on the latter.
- Ignoring humidity. Winter heating season drops indoor humidity into the teens, and ESD failures spike. If your facility runs dry in winter, re-verify glove performance in those conditions — or humidify.
- One glove for every job. Assembly, cleanroom, and rework have different binding constraints. Standardizing on a single SKU for simplicity usually means at least one task gets the wrong glove.
