Published date: 20 April 2022

Back to Article Listing

The electronic manufacturing industry, like every specialised sector, has developed a jargon that can sometimes be difficult to decipher that’s why we’ve put together a glossary of electronic manufacturing. Many terms are turned into acronyms and used with the assumption that everybody knows what they mean.

In this post, we have compiled a glossary of electronic manufacturing explaining the terms most commonly used in the electronic manufacturing sector.

AOI – Automated Optical Inspection

A tool that visually inspects a printed circuit board assembly.

ATE – Automatic Test Equipment

A machine used to electrically test boards and confirm their functionality.

BGA – Ball Grid Array

Integrated Circuit package that uses the underside of the chip for connectivity.

BOM – Bill of Materials

A list of all the materials needed to produce an electrical assembly.

Burn-in Testing

Electrically stressing a device to root out defects.

Capacitor

A PCB component used to store an electric charge.

CEM – Contract Electronic Manufacturing

A provider of design, manufacture, test and distribution services for electronic components and assemblies to OEMs.

DFM – Design for Manufacturing

The process of designing products in the most cost effective manner, within the shortest time frame, while maximising quality.

DMR – Defective Material Report

The report used to communicate details of a product that failed to comply with quality standards.

EAU – Estimated Annual Usage

The amount of product that a customer expects to purchase from a supplier within a year.

EMS – Electronic Manufacturing Service

FAI – First Article Inspection

The process that certifies that a product complies with the agreed design specifications.

HASL – Hot Air Solder Levelling

Process in which PCBs are immersed in molten tin/alloy to provide surface finish.

IC – Integrated Circuit

An electronic circuit formed on a small piece of semiconductor material.

ICT – In Circuit Test

A parametric test that ensures that correct components are placed on a circuit board and they are oriented the correct way.

MOQ – Minimum Order Quantity

PCB – Printed Circuit Board

A device that electrical components are soldered onto.

PCBA – Printed Circuit Board Assembly

The assembly of electronic components onto the PCB, resulting in a finished product.

PFMEA – Process Failure Mode Effects Analysis

An analysis used to identify risks and possible errors in manufacturing.

Resistor

A passive, two-terminal PCB component that employs electrical resistance as a circuit element.

RoHS– Restriction of Hazardous Substances

An EU directive restricting the use of dangerous substances (such as lead) in electronic manufacturing.

RFQ – Request for Quotation

The process by which a customer submits an order to obtain price and delivery information for a product or service.

SCM – Supply Chain Management

The process of managing the movement of goods within an organisation.

SLA – Service Level Agreement
