2.1.2 Training Plan
All employees are required to complete ESD training before allowed access to ESD Control Areas. All new
employees are required to complete an ESD orientation before they begin work. It is recommended that all
employees who handle static sensitive parts/assemblies or who work in ESD control areas should receive an ESD control review course once a year. If the ESD compliance score fall below 85% as per the Flextronics
Automotive Inc. audit checklist the site will be required to retrain employees in the affected areas.
ESD non-compliances identified during the audits should be the part of the training process. The training
department or the supervisors will maintain the training record for all employees trained on ESD.
The site ESD Coordinator or his designate shall train and verify the competency of those who deliver
ESD training. Verification of competency shall be undertaken for the following -
a) Amendments to the corporate training material
b) Where the trainer has not been involved in ESD training for a period of 6 months c) Where there are changes in customer ESD requirements
2.1.3 Compliance Verification Plan

D. 3rd
Party Audits Third party audits shall be conducted on an annual basis. The audit will be done to verify ESD
compliance to Flextronics Automotive Inc. procedure and checklist. The results of the audit will be
shared with the Site Operation Manager.
2.2 ESD Control Program Technical Requirements
2.2.1 Grounding / Bonding Systems Guidance Grounding of workstations, carts, storage shelving and personnel is necessary (where applicable) to provide a constant and gradual discharge path for static energy so that it is never
allowed to build to levels that can damage electronics.
Appropriate methods for grounding include but not limited to:
A. 3rd
wire AC (Preferred Method) In most cases, the 3
rd wire AC equipment ground is the preferred ESD ground. When this is
impractical or not available to use, personnel should be bonded or electrically connected to a
conductive element of the ESD item or container using a wrist strap or other grounding system
to ensure that all elements are at the same electrical potential i.e., a wrist strap may be connected to a cart or chassis containing ESD items that are being worked on.

Electrical power ground should be free of hazardous transient voltages, and regularly tested for continuity to ground. Caution: Connections to the electrical safety ground should only be made
by person knowledge about the power system being accessed.
B. Supporting Pillars
Supporting pillars in the buildings campus could be considered grounded. Any rigid, fixed,
metallic structure (e.g. copper air tubes) could also be considered ground, provided they are
connected to an unpainted section of a supporting pillar in such a way that the connections are reliable and tamper resistant. The pillars should be connected to the earth and regularly tested
for continuity to ground.
C. Copper Wire
The reference for ground could be a solid copper stake at least six feet long and 1/2” diameter
which has been driven into the earth. Brackets should be attached to the top of the stake so that cables can be securely fixed to the stake (see figure 1). Cables should always be connected to
the nearest, best ground source.

Figure 1, Grounding Bracket
Ground reference sources and preferred grounding methods shall be defined and documented
for each site if necessary.
2.2.2 Personal Grounding
The required ESD protection for "ALL" employees is for each to wear an ESD smock together with heel straps/toe straps or ESD footwear (in ESD safe areas). Smocks shall be worn with at
least three of the front snaps closed. Smocks may be worn with sleeves rolled up providing that
the clothes underneath the smock do not protrude beyond the sleeve line and, in the case of
smocks which function through surface conductivity; there is a portion of sleeve in contact with the wearer’s skin. As a general rule, the wearer’s clothes should not be exposed to static
sensitive devices or assemblies.

The person sponsoring the visitor is responsible for ensuring that they; are provided with all
required ESD protective equipment when the scope of the visit requires access to ESD sensitive
areas, that the visitor has ESD tested and passed the equipment, and that they comply with this procedure while being in a Flextronics Automotive Inc. facility.
A. Wrist Straps
A wrist strap is required for anyone handling ESD components or assemblies while seated,
regardless of heel grounding. (However, personnel exposed to greater than 500V should be considered a special case.) Wrist straps are to be tested at least daily, before handling ESD
sensitive items. Putting approved* lotion on the skin contact site and/or adjusting the strap may
help it to pass. If the strap still fails it must be replaced. After passing, each operator must sign off startup check list as applicable, which must be current and visible.
(*Note: Lotion approved for use in the manufacturing area must be free of silicone and lanolin,
and the bottle should be safe for use within an ESD control area, as appropriate. The local Engineering department and ESD coordinator should verify this.)
B. Heel Straps
Heel straps, or conductive shoes, may be used to ground personnel in areas where there are grounded conductive or dissipative floor mats, or where the floor's resistance to ground
measures between 104 and 109 ohms. The use of heel straps as additional (secondary) grounding devices to help drain static charge generated while walking is encouraged, and may
be required by area management. It is required that the personnel wear one heel strap at all
times – also if wearing ESD safe shoes the personnel does not necessary have to wear the heel strap. ESD shoes must have a visible tag or marking on the outside of the shoe to indicate that
they are ESD shoes
Conductive heel straps and shoes shall be tested before handling ESD items each day. Heel
straps and shoes that fail the test should be cleaned, adjusted, and retested. If the strap/footwear
still fails it must be replaced. After passing, each person must sign off startup check list if
applicable, which must be current and visible.
C. Smocks
Smocks must be worn in all manufacturing areas. They must be audited for effectiveness at least annually, and replaced as needed. Smocks may be checked for effectiveness in one of two
ways: (1) A surface resistivity meter may be used to check that the point to point resistance of
the fabric is within the dissipative range, (2) A charge is applied to the smock (using a charged plate analyzer) and then a field meter or static voltmeter is used to verify that the charge is
dissipated across the seams. ESD smocks shall, as a minimum, cover all personal garments
above the waste in accordance with JEDEC (625-A) requirements.
D. Floor Mats
Grounded, conductive or dissipative floor mats may be necessary in areas approved for
conductive footwear (see section 2.2.2 B). The mats should be cleaned as needed with an approved antistatic cleaner to prevent the buildup of non-conductive particles on the mats.

2.2.3 Protected Area
A. Signs
Signs should be posted at all entrances to ESD control areas, and the boundaries of these areas
shall be clearly identified. The signs should identify the area as an ESD control area and display the JEDEC (Joint Electronic Device Engineering Council) susceptibility symbol.
Yellow or fluorescent orange-red is the preferred colors for ESD caution signs and labels.
JEDEC susceptibility symbol

B. Floor
The floor shall be kept clean at all time, magazines should not be on the floor with or without PCBs. Dragging the magazines on the floor will damage the floor and it’s resistance to the
ground. The recommended resistance to ground (RTG) of floors in an ESD control area should
be maintained between 104 and 109 ohms (using a 100V test voltage). This condition is mandatory if the floor is used to ground people or carts in the area. Recommended range for
newly installed floors the RTG should be between 104 and 106 ohms. C. Environment Whenever possible, relative humidity in an ESD control area shall be maintained to a minimum
of 30%. If the humidity within the production area falls below 30%, the site ESD Coordinator
shall assess if an increased ESD risk. Where this is considered to be likely, the site ESD Coordinator shall implement whatever measures are considered necessary to mitigate the
increased risk. The temperature shall be between 18C and 27C (64.4 degree Fahrenheit 80.6 degree Fahrenheit).

ESD protective packaging and package marking shall be in accordance with the contract, purchase order, drawing or other documentation. When the contract, purchase order, drawing or
other documentation does not define ESD protective packaging, the Site shall define ESD
protective packaging requirements for ESD items. Some of these types and techniques include low charge generating bags and wraps, air space, dissipative wrap, static shielding, conductive
shunts and the use of EMI/RFI shielding.
Packaging shall be defined for all material movement within Protected Areas, between job sites
and field service operations.
2.2.5 Marking
ESD assemblies and equipment containing ESD parts and assemblies should be marked with an ESD caution symbol as shown in Figure 2.
2.2.6 Equipment
A. Work Stations and Tables
Workstations and tables in an ESD control area must have static dissipative surfaces and should
be connected in parallel. Each workstation must have available wrist strap ground connections (two are recommended), preferably banana jack receptacles. Work surfaces should be cleaned
daily with an antistatic cleaner, and the resistance to ground should be maintained in the static
dissipative range. Surfaces and wrist strap grounding receptacles must be physically wired, in parallel, to the building ground source.
All tables and workstations within an ESD control area shall have the grounding electrically
verified and recorded monthly as determined by the site ESD Coordinator or management specified representative. (See section 2.1.3.1 C) This plan would be documented in the site-
tailoring document. Ground connections should have less than two ohms resistance.
B. Wrist Strap Tester Wrist strap testers or continuous monitors must be used to test the functionality of all wrist
straps. All testers must be calibrated annually. They should be set to accept on readings from
500,000 ohms to 35 Meg ohms resistance. A monthly functional check of each tester is a requirement.
The tester will be checked monthly for functionality the responsibility and authority lies with
the Site ESD coordinator. Please refer to Table 1.
C. Conductive Footwear Tester
Footwear testers must be used to test the functionality of all heel straps and conductive shoes.
All testers must be calibrated annually. They should be set to accept on readings from 500,000 ohms to 35 Meg ohms resistance. A monthly functional check of each tester is a requirement.
The tester will be checked monthly for functionality the responsibility and authority lies with
the Site ESD coordinator. Please refer to Table 1.

D. Carts and Movable Racks Cart frames should be static dissipative or conductive. In the case of conductive carts, ESD
sensitive materials cannot come in direct contact with the cart. There should be bare metal or
cable connections between the shelves and supports to ensure a path to ground for each shelf. The carts must also be grounded (in areas with dissipative flooring, carts may be grounded by
means of an attached drag chain, or flat, braided cable, with at least two inches of its length in
contact with the floor).
E. Power Tools
Power tools, including soldering irons, need to be grounded (grounding to the local utility is
usually sufficient, but this determination should be made by the site Engineering dept.).
F. Air Ionizers
Air ionizers may be used to reduce the static charge on objects within the process area, which are chargeable to, or generate greater than 100 volts (as determined by Engineering). Ionizers
should be turned on at least 2-3 minutes before unprotected ESD sensitive items are handled
nearby, and should primarily be focused such that the ionized air surrounds the sensitive
devices.
Ionizers shall be cleaned and tested for functionality at least monthly. Air ionizers shall be
tested monthly for positive and negative decay and balance, and adjusted, if necessary, to ensure the final balance is below 30V and the decay times do not exceed 5 seconds each. Ionizers shall
be serialized and test data recorded by serial number. Ionizer test logs should include, at a
minimum: test date, decay time for a positive charge, decay time for a negative charge, final balance, notes of corrective action, and the initials of the person performing the tests. Self-
balancing ionizers, which do not require adjustment according to the manufacturer, need not be
tested monthly. However, should receive maintenance according to the manufacturer's
recommendations.
G. Topical Antistat
Topical antistatic treatment of chargeable objects may be used providing that its effectiveness is checked regularly (the recommended frequency is weekly) and renewed as needed. Caution:
Some topical antistatic chemicals will cause cracking of polycarbonate plastics.
H. Gloves and Finger Cots (Optional) To aid in contamination control and/or to handle hot (high temperature) ESD parts and/or cards,
static safe gloves or finger cots may be required. Their function, when and how they are to be
used shall be specified in the process routings. Note: Although it is desirable to have conductive or static dissipative gloves for static
protection purposes, other issues often force compromises in material selection. Some available
gloves are not conductive, but they do not generate static charges during normal use. Questions regarding various glove compositions should be directed to the Site ESD Coordinator.

All parts bins and containers used in any manufacturing process must be static dissipative or antistatic. Sensitive parts should remain in the original protective container if practical until
assembled.
J. Shelving and Cabinets
All shelving and cabinets used for storage of ESD components must provide a grounded surface
unless the parts remain fully enclosed within shielding-type packaging such as approved ESD
bags or original manufacturer’s packaging such as SMT reels and IC trays.
2.2.7 Handling
Direct handling of unprotected ESD sensitive (ESD) parts, assemblies, or products, shall only
be by grounded personnel within an ESD control area. Unprotected ESD items should not be
allowed to come in direct contact with grounded, conductive equipment housings or metal surfaces (for example, metal shelves and carts).
To move ESD parts or assemblies inside an ESD control area, use one of the following:
a. Static dissipative containers
b. Static shielding containers c. Conductive containers or board carriers
d. Grounded movable racks (see section 2.2.6 D)
Open containers and board carriers should be transported on grounded carts
A. Transportation
Off-Site: To move components and assemblies off-Site, use only closed static shielding containers (original, closed, vendor packaging is also acceptable). Antistatic packaging (for
example, DIP tubes) alone is not sufficient for this purpose. The containers should also be
labeled as containing static sensitive items.
Between Buildings On Site: To move components and assemblies between buildings (intra-site), use only closed static shielding containers, and ESD safe carts and/or in Faraday cage. (See sec
2.2.6.D). All ESD protection measures must be utilized and items must not be left unattended
while in transit Between ESD Control areas within Building: All ESD protection measures must be utilized and
items may not be left unattended while in transit
B. Static Generating Material All process essential insulators that have electrostatic fields that exceed 2,000 volts should be
kept at a minimum distance of 12 inches from ESD items. If these "static generators" are
essential to the effective operation of processes in the area, steps must be taken to minimize the risk the materials represent (see Table 2). Any signs posted at workstations shall be posted in
anti-static sheet protectors or plain paper. Ordinary plastic sheet protectors or document holders
should be avoided in an ESD safe area and in any case must not come within 12” of unprotected parts or assemblies.

Records Retained for a period of one year.
Definitions Antistatic Material — material, which resists triboelectric charge generation (i.e. generating static charges by
rubbing or other type of contact). Antistatic materials are not static shielding (see Table 3).
Conductive Material — material with surface resistivity less than 105 ohms per square. Conductive material will
shield an object completely enclosed within it from a charge, will dissipate charges immediately, and must be grounded. Ungrounded conductive materials will accept/generate charge (see Table 3).
Decay Time — the time required to reduce the initial voltage, U1, of a charged material to a defined lower voltage
level, U2.
ESD — electrostatic discharge. A sudden transfer of electrostatic charge between objects at different potentials caused by direct contact or induced by an electrostatic field.
ESD Control Area — any area where unprotected static sensitive parts may be handled (see section 2.1).
ESD Model – Human Body Model (HBM) - Three-circuit models are used to analyze the effects of ESD. They are
“The Human Body Model” (HBM), “The Charged Device Model” (CDM) and “The Machine Model” (MM).
These models help determine the resistive ranges for safe static discharge.
People are a primary source of static charge accumulation. Hair, hair products, types of clothing and type of shoes
worn all affect the way the human body can collect and store a charge. Actions such as walking, sitting, or
handling a product can cause an ungrounded body to develop a significant static charge.
The Human Body Model (HBM) characterizes a static event resulting from a charged person discharging to a static
sensitive device. Typically, the human body senses (hear, see, feel) static discharges at levels above 3500 volts. We hear the POP! We see the SPARK! We feel the JOLT! At levels below 3500 volts, we cannot (through the
use of the body) detect when a static event occurs.
The charge that the human body is able to carry is sufficient to damage an ESD-sensitive component. The
damaging effects of electrostatic discharge are not always immediate and often difficult to detect. A card could be
damaged due to a static event and still pass in-circuit and functional tests! The safest practice to guard against
static discharge from people is personnel grounding.
ESD Sensitive (ESD) — Describes any device or assembly whose electrical characteristics or performance can be
altered by exposure to static electric charge or a discharge through its conductors.

Faraday Cage — a closed conductive container, which provides ESD protection because all external charges are
distributed over its outside surface. No externally caused field is detectable inside a Faraday cage.
Ground — a conductor connected to the earth, and hence, used as a reference point for zero potential (“hard
ground”).
Insulative Material — material with a surface resistivity greater than or equal to 1012 ohms per square. Insulative material accepts/generates charges readily but will not dissipate a charge. The material cannot be grounded and is
not static shielding (see Table 3).
RTG — resistance to ground
Static Dissipative Material — material with a surface resistivity greater than or equal to 105 but less than 1012 ohms
per square; however, the preferred operating definition for non-packaging materials is >105 and <109 ohms per
square. Static dissipative material is not static shielding, will dissipate charges in a controlled manner and must be grounded. Ungrounded static dissipative materials will accept/generate charge (see Table 3).
Static Shielding Material — material with a conductive layer or surface. Containers made of static shielding material should completely enclose their contents and be able to be sealed. When a static shielding container is
closed, the conductive layer in the material forms a Faraday cage that does not allow an ESD or electrostatic field
to pass, penetrate or puncture through the material.
Surface Resistivity — a measure of the resistance of a material to electric current on its surface. It is the ratio of
direct current (dc) voltage to the current that passes across the surface of a material (expressed in ohms per square).
