Whois & Analysis for 4pcb.com

A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate.

Components (e.g. capacitors, resistors or active devices) are generally soldered on the PCB.

Advanced PCBs may contain components embedded in the substrate.

The ampere (SI unit symbol: A, dimension symbol: I), often shortened to "amp", is a unit of electric current.

In the International System of Units (SI) the ampere is one of the seven SI base units.

It is named after André-Marie Ampère (1775–1836), French mathematician and physicist, considered the father of electrodynamics.

The Department of Defense (DoD, USDOD, or DOD) is an executive branch department of the federal government of the United States charged with coordinating and supervising all agencies and functions of the government concerned directly with national security and the United States Armed Forces.

The Department is the largest employer in the world, with nearly 1.3 million active duty servicemen and women as of 2016.

Adding to its employees are over 801,000 National Guardsmen and Reservists from the four services, and over 740,000 civilians bringing the total to over 2.8 million employees.

It is headquartered at the Pentagon in Arlington, Virginia, just outside of Washington, D.C.

Manufacturing is the value added to production of merchandise for use or sale using labour and machines, tools, chemical and biological processing, or formulation.

The term may refer to a range of human activity, from handicraft to high tech, but is most commonly applied to industrial production, in which raw materials are transformed into finished goods on a large scale.

Such finished goods may be sold to other manufacturers for the production of other, more complex products, such as aircraft, household appliances or automobiles, or sold to wholesalers, who in turn sell them to retailers, who then sell them to end users and consumers.

In the microelectronics industry a semiconductor fabrication plant (commonly called a fab; sometimes foundry) is a factory where devices such as integrated circuits are manufactured.
