Whois & Analysis for ourpcb.com

A printed circuit board (PCB), also called printed wiring board (PWB), is a medium used to connect or "wire" components to one another in a circuit.

It takes the form of a laminated sandwich structure of conductive and insulating layers: each of the conductive layers is designed with a pattern of traces, planes and other features (similar to wires on a flat surface) etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate.

Electrical components may be fixed to conductive pads on the outer layers in the shape designed to accept the component's terminals, generally by means of soldering, to both electrically connect and mechanically fasten them to it.

Another manufacturing process adds vias, plated-through holes that allow interconnections between layers.

In macroeconomics, an industry is a branch of an economy that produces a closely related set of raw materials, goods, or services.

For example, one might refer to the wood industry or to the insurance industry.

Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation.

It is the essence of the secondary sector of the economy.

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

Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers).

Home computers were a class of microcomputers that entered the market in 1977 and became common during the 1980s.

They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single, non-technical user.

These computers were a distinct market segment that typically cost much less than business, scientific, or engineering-oriented computers of the time, such as those running CP/M or the IBM PC, and were generally less powerful in terms of memory and expandability.

However, a home computer often had better graphics and sound than contemporary business computers.

Their most common uses were word processing, playing video games, and programming.
