Overview

IEC 61340-5-3:2015 is an international standard published by the International Electrotechnical Commission (IEC) that addresses the protection of electrostatic discharge sensitive (ESDS) electronic devices through effective packaging. The standard specifies the essential properties and requirements for packaging materials designed to safeguard such devices from electrostatic discharge (ESD) throughout all phases-production, rework, transport, and storage.

This second edition replaces the 2010 version, introducing key technical updates such as replacing ANSI/ESD STM11.13 references with IEC 61340-4-10, enhancing classification tables for packaging, and introducing an ESD classification symbol system with primary function codes. Importantly, the standard focuses exclusively on electrostatic phenomena, excluding electromagnetic interference (EMI), electromagnetic pulsing (EMP), or protection of volatile substances.

Key Topics

• ESD Protective Packaging Properties
  IEC 61340-5-3 defines material characteristics such as resistance (conductive, dissipative, insulating) and electrostatic shielding properties necessary to prevent electrostatic discharge damage.

• Classification and Marking
  The standard provides a clear classification system for packaging based on material properties and functionality, including mandatory markings that denote the ESD classification symbol and primary function code. This supports traceability and easier identification during handling.

• Test Methods and Performance Limits
  Referenced test procedures evaluate packaging materials against standardized requirements, ensuring consistent protection across different manufacturing and logistics environments.

• Tailoring for Environment and Device Sensitivity
  Guidance is offered to tailor packaging requirements according to the specific environmental conditions and the sensitivity of the electronic devices, ensuring appropriate levels of ESD protection.

• Scope of Protection
  The standard applies to packaging used inside and outside electrostatic protected areas (EPA), addressing the entire supply chain from material receipt to end-use.

Applications

IEC 61340-5-3 is critical for industries involved in the manufacture, handling, and transportation of electronic components and devices that are sensitive to electrostatic discharge. Practical applications include:

• Manufacturing: Packaging materials compliant with IEC 61340-5-3 prevent ESD damage during device assembly and testing within a production environment.

• Rework and Maintenance: Protective packaging assists in safe handling during servicing or refurbishing electronic modules, reducing risk of discharge damage.

• Logistics and Storage: Shipping and storage of ESDS devices require packaging that adheres to the standard’s classification to maintain device integrity through transit and warehousing.

• Quality Assurance: The standard’s traceability and marking systems facilitate quality control inspections, ensuring that appropriate protective packaging is consistently used.

Utilizing IEC 61340-5-3 compliant packaging effectively mitigates risks associated with static electricity, thereby enhancing product reliability and reducing costs due to ESD-related failures.

Related Standards

IEC 61340-5-3:2015 is part of the broader IEC 61340 series on electrostatics protection, which includes:

• IEC 61340-4-10: Test methods for evaluation of ESD protective packaging materials, now a normative reference within IEC 61340-5-3.

4 Tailoring
This standard, or portions thereof, may not apply to all applications. Tailoring is accomplished
by evaluating the applicability of each requirement for the specific application. Upon
completion of the evaluation, requirements may be added, modified or deleted.
Tailoring decisions, including rationale, shall be documented.
5 Packaging application requirement
5.1 General
Transportation of ESDS requires packaging that provides protection from electrostatic
hazards (for example from an electrostatic discharge). Within an EPA in which all ESD risks
are well controlled, ESD protective packaging may not be necessary.
5.2 Inside an EPA
Packaging used within an EPA shall consist of dissipative or conductive materials for intimate
contact.
Items sensitive to <100 V human body model (HBM) may need additional protection
depending on application and program plan requirements.
NOTE Dissipative materials are preferred for intimate packaging in situations where charged device model (CDM)
damage is a concern.
5.3 Outside an EPA
Transportation of sensitive products outside of an EPA shall require packaging that provides
both
a) dissipative or conductive materials for intimate contact,
b) a structure that provides electrostatic discharge shielding.

– 10 – IEC 61340-5-3:2015  IEC 2015
If electrostatic field shielding materials are used to provide discharge shielding, a material
that provides a barrier to current flow should be used in combination with the electrostatic
field shielding material.
NOTE Dissipative materials are preferred for intimate packaging in situations where charged device model (CDM)
damage is a concern.
6 Classification of ESD packaging material properties
6.1 General
Materials and packages that are useful in preventing damage to sensitive electronic devices
exhibit certain properties. These properties include:
a) resistance properties:
– conductive;
– dissipative;
b) shielding properties:
– electrostatic discharge;
– electrostatic field.
6.2 Material resistance properties
6.2.1 General
Most standard packaging materials are electrically insulating and insulating materials retain
charge. Making the package less insulating provides a path for the charge to dissipate from
the package to a material at a lower potential.
Specific ranges of resistance are useful for different purposes. Packaging can be classified by
these resistance ranges of the material used in its construction.
6.2.2 Resistance of conductive materials
Conductive materials may be surface conductive, volume conductive or both.
a) Surface conductive materials
A surface conductive material shall have a surface resistance of <1 × 10 Ω.
b) Volume conductive materials
Volume conductive materials shall have a volume resistance of <1 × 10 Ω .
6.2.3 Resistance of electrostatic field shielding materials
Within the conductive materials classification, electrostatic field shielding materials shall have
a homogeneous layer with a surface resistance of <1 × 10 Ω or a volume resistance of
<1 × 10 Ω.
Other methods may also define the electrostatic field shielding classification.
NOTE These resistance values do not necessarily imply EMI/EMP shielding.
—————————
The thickness of the material might have a significant influence on the measured value of a volume resistance.

6.2.4 Resistance of dissipative materials
Dissipative materials may be surface dissipative, volume dissipative or both.
a) Surface dissipative materials
4 11
Surface dissipative materials shall have a surface resistance ≥1 × 10 and <1 × 10 Ω.
b) Volume dissipative materials
4 11
Volume dissipative materials shall have a volume resistance ≥1 × 10 and <1 × 10 Ω .
6.2.5 Resistance of insulating materials
Electrostatic insulating materials may be surface insulating, volume insulating or both.
a) Surface insulating materials

Electrostatic surface insulating materials have a surface resistance ≥1 × 10 Ω.
b) Volume insulating materials

Electrostatic volume insulating materials have a volume resistance ≥1 × 10 Ω.
6.3 Material electrostatic shielding properties
NOTE Electrostatic shielding materials protect packaged sensitive electronic items from the effects of electrostatic
discharges and fields that are external to the package.
6.3.1 Electrostatic discharge shielding
Electrostatic discharge shielding packaging is capable of attenuating an electrostatic
discharge. The calculated energy allowed inside a static discharge shielding bag shall be less
than 50 nJ when tested according to IEC 61340-4-8 or equivalent test method modified to
accommodate the product.
6.3.2 Electrostatic field shielding
Electrostatic field shielding packaging is capable of attenuating an electrostatic field.
NOTE Classified field-shielding materials can allow current flow through their volume.
7 Technical requirements for ESD protective packaging
7.1 Packaging and material properties
Table 1 and 2 provide test methods for determining material classifications for finished
packages and materials. When possible, testing shall be performed on the finished package.
When testing cannot be performed on a finished package, the material classification shall be
defined by the bulk material used for the production of the final package.
—————————
The thickness of the material might have a significant influence on the measured value of a volume resistance.

ESD packaging material guidance
A.1 Environment and device sensitivity
A.1.1 General
Environment and device sensitivity are two primary considerations for selecting ESD
packaging materials.
A.1.2 Environment
Since the threat to a sensitive item is usually undetermined when the item is outside an ESD
protected area (EPA), electrostatic sensitive devices (ESDS) should be placed in ESD
protective packaging whenever the item is in an unprotected area (UPA) – see Table A.1.

A.1.3 Device sensitivity
If the sensitivity of the ESDS is unknown and the device is being shipped outside of the EPA,
it should be packaged using an electrostatic discharge shielding structure that also provides
protection against electrostatic fields.

However, if the sensitivity of the ESDS is known and the ESD threat environment is well
understood, the protection level of the packaging may be reduced.
A.2 Equipotential bonding
While not always recognized as being a packaging consideration, equipotential bonding, or
the shunting of leads, can be an effective method to mitigate damage. By placing a conductive
shunt across device leads or card connectors, the various parts of the item share the same
electrical potential. While not necessarily at ground potential, the fact that parts of the item
share the same potential means that damaging current will not flow between them. Shunting
has limitations. Energy from direct discharge and electric fields may impact the item in a
manner that does not allow the energy to equalize through the shunt, but instead through the
device. ESD protective packaging that offers other protective properties is usually used in
conjunction with shunting devices.
A.3 Dissipative material for intimate contact
To avoid rapid discharge of ESDS due to contact with conductive surfaces, dissipative
materials are preferred.
A.4 Packaging from incoming material to the point of use
Figure A.1 shows a simplified layout of a generic electronic packaging application. Each area
has the recommended ESD packaging material properties noted. As discussed in A.1.3, if the
item sensitivity and threats are documented, the level of protective packaging can be reduced
after confirming packaging functionality.
NOTE This layout shows an “islands of protection” approach to ESD safeguards. Many manufacturing processes
employ a “total factory” approach, where the entire factory is a safeguarded area – see Figure A.1.

It may happen that the two-point-probe described in IEC 61340-4-10 does not fit inside the cavities. Other test
methods outside the current scope of this standard may then be needed to be used to measure the packaging
limits.
The compliance verification plan according to IEC 61340-5-1 [1] should document the
method used to verify the limits according to the material classification in Table A.2.

Device damage
B.1 Damage from ESD
Damage to devices usually occurs in one of two situations:
– electrostatic discharge to a device;
– electrostatic discharge from a charged device.
This distinction is important for packaging considerations because different properties are
required to manage each situation. The source of the static electricity needs to be considered
and then the path the charge travels to damage the device.
B.2 Discharge to a device
B.2.1 Human body model (HBM) [2] and isolated conductors
Common items that discharge to packaged devices include the human body and conductive
objects used to handle packages like conveyors, carts and vehicles. Tribo-electrification is
usually the charge source.
Since the discharge must pass through the package to reach the device, the package can be
used to protect the device from an ESD event external to the package.
B.2.2 Retained charge
The package can gain charge from ESD or tribo-electrification. Where the package exterior is
isolated from the package interior and therefore the device, it is possible for charge on the
package to discharge to the device as it is removed from the package.
B.3 Discharge from a device
B.3.1 Charged device model (CDM)
If a device is momentarily grounded in the presence of an electric field emanating from an
electrostatically charged item, a discharge occurs and the device retains a charge of opposite
polarity. When the device contacts an object with a different potential, like a grounded hand
removing the device from a package, an electrostatic discharge occurs. Since the electric field
passes through the package, the package can be used to protect the device from a field that
is external to the package. The package may also isolate the device from ground.
B.3.2 Tribo-electrification
As a device and package move in relation to each other, charge can accumulate on the
package and on the device. When the charged device contacts an object with a different
potential, an electrostatic discharge occurs.
