Electronic assembly is the process of putting together electronic and electrical parts that form an electronic circuit or the electronic component. The process may also include attaching things such as cables and connectors, etc. The electronic assembly sector is generally broken into two sections, which includes the assembly of electronic components on boards, and the assembly these boards into larger electronic systems. Electronic assembly may also involve tasks such as helping assist in the design, manufacturing, and controlling costs of these components, along with soldering and other operations like parts performance testing, etc.
Typically, electronic component manufacturers buy various types of components such as printed circuit boards, resistors, chips, semi conductor devices, processors, heat sinks, cables and wiring, connectors, etc. They then set up an assembly line in which the electronic components are assembled manually or through automated assembly lines using work stations. So even though you may be buying a brand name electronic device such as a television, the odds are that only a certain number of the television's components were actually built in that company's factory.
There';s a good chance that some of the components were made by another company and then sold to the manufacturer of the television. The outsourcing of electronic assembly work is very common in the industry and has been going on for many years.
Automated assembly lines are usually more expensive to setup and they are often only used when the quantities to be assembled are on the smaller side. Automated assembly lines are usually powered by a conveyor belt or another type of conveyor system and robotics is used to assemble the devices. These types of assembly lines have very fast production rates and are more consistent as human errors are avoided. Typical examples are mobile phones, watches, and radios etc. where the parts are smaller and the benefits of using automated lines become very important. Manual assembly lines also use a conveyor belt or other type of conveyor system, but are usually used to assemble larger devices such as TVs, large audio systems, refrigerators, and microwave ovens, etc. where the individual parts are also larger.
