Discharge Controls and Procedures
discharge (ESD) is the sudden flow of electricity between
two objects caused by contact, an electrical short, or dielectric
breakdown. ESD can be caused by a buildup of static electricity
by tribocharging, or by electrostatic induction.
purpose of this ESD document is to provide information regarding
controlling ESD in order to improve the performance and quality
of the products Xmultiple manufactures. Control of ESD is
for all Xmultiple factories as well as control of Xmultiple
material suppliers. It is intended to educate and train all
personnel and especially our engineering, operations and quality
control personnel. ESD control and procedures are to be used
in our manufacturing factories employee's day-to-day responsibilities.
includes spectacular electric discharge, but also less dramatic
forms which may be neither seen nor heard, yet still be large
enough to cause damage to the electronic products we manufacture.
can cause a range of harmful effects of importance in our
interconnect solutions industry, including failure of solid
state electronics components such as integrated circuits used
in our products. These can suffer permanent damage when subjected
to high voltages. Xmultiple has established electrostatic
protective areas free of static, using measures to prevent
charging such as avoiding highly charging materials, and measures
to remove static. Xmultiple uses ESD protective products to
ground our factory manufacturing workers. Xmultiple uses antistatic
devices in all factory manufacturing work areas and for protecting
products in antistatic bags used through the movement of our
products inside our factories. We also control humidity in
all our factories to eliminate ESD. ESD simulators are used
to test products during the manufacturing process. Xmultiple
trains all factory manufacturing employees on ESD on an ongoing
basis. ESD materials such as antistatic mats, shoe coverings
and wrist bands are purchased from 3M Corporation. Xmultiple
distributes the 3M ESD Handbook to all factory manufacturing
employees and uses this handbook as the ESD training tool
for manufacturing personnel in our manufacturing, storage
and shipping areas.

training and use is shared among all Xmultiple factory manufacturing
employees and personnel who come in contact with ESD-sensitive
equipment used in any of our manufacturing facilities, packaging,
and shipping areas or for any employee coming in contact with
our products before they are delivered to our customers. ESD
protective packaging is used for all our products. The Electrostatic
Discharge Control EPA sign is displayed in our factory manufacturing
ESA Protection Area (EPA) includes the following six groups
which are controlled, monitored and maintained in all of our
factory manufacturing facilities.
ESD environment: Flooring, grounding, ionizers,
ESD products: ESD products including: Static shielding
bags, bins, boxes, organizers, carts, shelving, IC tubes and
other ESD packaging for components.
ESD workbench and ancillaries: The use of
an ESD workbench with ESD straps, ESD seats, etc., to ensure
our personnel are grounded via a high resistance dissipative
rather than conductive path for safety reasons.
ESD tools: A variety of tools come into this
category including ESD soldering irons.
ESD clothing: The use of ESD clothing. Normal
clothing can generate and carry static.
ESD storage and transport: Our connectors
and components are ESD protected before and during shipping
to our customers.
wide range of ESD Products/Devices are used by Xmultiple in
the manufacturing of our products.
