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

Gas tungsten arc weldingTwin-carbon arc weldingTwin-carbon arc welding, in contrast to carbon arc welding with a single electrode, is carried out with arc excitation between two carbon electrodes in a special holder. Two electrodes, after touching, are divorced, while the electric arc lights up and is maintained.
Twin-carbon arc welding, in contrast to carbon arc welding with a single electrode, is carried out with arc excitation between two carbon electrodes in a special holder. Two electrodes, after touching, are divorced, while the electric arc lights up and is maintained.
The size of the arc depends on the distance between the electrodes, the diameter of the electrodes and the welding current. The heat generated can be controlled by changing the size of the arc or the distance between the arc and the workpiece. After the arc has started, welding can be carried out in the same way as in the TIG process.
Dual carbon arc welding is recommended for AC power. With direct current, the positive electrode will degrade faster than the negative electrode, because two-thirds of the total heat is generated at the positive pole. This will lead to arc instability and require frequent electrode changes. When welding with alternating current, both electrodes will work the same way.
The amount of arc current required for welding depends on the diameters of both electrodes and the thickness of the workpieces. For example, with a diameter of 8 mm, a current of about 65 amperes is needed to weld mild steel sheet with a thickness of 3.5 mm and 80 amperes for welding a sheet with a thickness of 6 mm.
Double carbon arc welding has the advantage that the arc can be moved to any point on the workpiece without extinguishing it. In addition, the blanks are not part of the electrical circuit. With double carbon arc welding, metal loss is reduced - less fumes and spatter are formed.

Electronics industry
Electronic industry Electronic industry - the industry for the production of electronic components and products from them, the most science-intensive branch of modern engineering, in general, up to 2/3 of all products of the electronic industry - this is the most complex science-intensive technology.
The electronic industryThe electronic industry is the brainchild of the scientific and technological revolution, the role of the scientific potential of countries and firms in the development of new (innovative) types and types of its products and the creation of advanced production technologies is extremely great. This predetermined close cooperation between research institutions and manufacturing enterprises. In the conditions of market competition, it was necessary to drastically reduce the time cycle from product development to its release. This was done in technopolises (such as the famous Silicon Valley in the USA). They practically do not have a territorial (and hence temporal) gap between scientific research and production, thereby achieving high economic efficiency of the entire cycle - from the moment a new idea appears to the mass production of goods.
