Electronic contract manufacturing
Electronic manufacturing services
EMS

Electronic manufacturing services (EMS) is a term used for companies that design, test, manufacture, distribute, and provide return/repair services for electronic components and assemblies for original equipment manufacturers (OEMs). The concept is also referred to as electronic contract manufacturing (ECM).

EEE Part


Electrical, electronic, and electromechanical parts are components designed and built to perform specific functions, and are not subject to disassembly without destruction or impairment of design use. Examples of electrical parts include resistors, capacitors, inductors, transformers, and connectors. Electronic parts include active devices, such as monolithic microcircuits, hybrid microcircuits, diodes, and transistors. Electromechanical parts are devices that have electrical inputs with mechanical outputs, or mechanical inputs with electrical outputs, or combinations of each. Examples of electromechanical parts are motors, synchros, servos, and some relays. Defined in Section 818, paragraph (f)(2) of PL 112-81-Dec 31, 2011 as “an integrated circuit, a discrete electronic component (including, but not limited to, a transistor, capacitor, resistor, or diode), or a circuit assembly.” It also includes any embedded software or firmware.

Electronic Resellers Association International


ERAI, Inc. was formerly known as the Electronic Resellers Association International.
Electronic Waste


Discarded electronic devices, assemblies, sub-assemblies, components, and substances involved in their manufacture or use. E-Waste is exported to lesser-developed low wage nations such as China, India and parts of Africa due to mediocre or non-existent environmental standards and working safety laws. According to the US Environmental Protection Agency, millions of tons of electronic waste is gathered and exported annually to these regions. Only a small percentage of the waste collected is recycled. The balance of this material is exported overseas to “dismantling shops” where precious metals and electronic components are extracted for resale. This continuous supply of material is fueling the counterfeit market. International treaties are supposed to prohibit and deter the exportation of obsolete computer hardware from developed to developing countries; however, there are loopholes in the system. The waste that is sent to these regions for processing is done so illegally by transporting the goods through alternate ports, disguised as charitable donations or is done despite international laws and with lack of controls. It is well known that China is the largest recipient of E-Waste and that they have found more than one way to profit from global waste disposal. In certain regions of China, entire communities rely on E-Waste and counterfeit component trade as a source of revenue. (Also see ERAI Special Report Titled: A TIME FOR CHANGE)
Electrostatic Discharge

ESD

The rapid, spontaneous transfer of electrostatic charge induced by a high electrostatic field. Note: Usually, the charge flows through a spark between two bodies at different electrostatic potentials as they approach one another. Details of such processes, such as the rate of the charge transfer, are described in specific electrostatic discharge models.

Electrostatic Discharge Sensitivity

Electrostatic Discharge Susceptibility
ESDS

The lowest level level of electrostatic discharge (ESD) that produces changes in device characteristics such that the device fails to meet its specified parameters.

Electrostatic Discharge Shield

ESD Shield

A barrier or enclosure that limits the passage of current and attenuates an electromagnetic field resulting from an electrostatic discharge. See ANSI/ESD S541, Packaging Materials for ESD Sensitive Items, for more information about ESD shielding and appropriate packaging materials.

Exterior Defect


(1) A counterfeit indicator. (2) Defects related to product packaging and/or shipping (e.g. invalid date or lot code, paperwork, product labels, etc.); part leads, balls or columns (e.g. oxidation, exposed copper, scratches, dents, etc.); package (e.g. unidirectional abrasions/sanding, burn marks, inconsistent texture, package mold variations, etc.) See: Physical Defect, Interior Defect Note: “Exterior defects are related to packaging/shipping, leads/balls/columns, and package of a component. The most obvious defects will be ones that are associated with the packaging or shipping the parts arrived in. The leads/balls/columns of an IC can show how the part has been handled if it was previously used. Physically, they should adhere to datasheet specifications, including size and shape. The final coating on the leads should conform to the specification sheet. The package of an IC can reveal significant information about the chip. As this is the location where all model numbers, country of origin, date codes, and other information are etched, counterfeiters will try to be especially careful not to damage anything and to keep the package looking as authentic as possible.”"
