Circuit Board
What's printed circuit board?
Printed circuit board, also known as printed circuit boards or PWB(printed wiring board), electrical connection of electronic components provider. With development over 100 years of history,it is designed mainly to layout; The main advantage of using circuit board layout and assembly are greatly reduced errors, improved the level of automation and production labor rate.
History:
The inventor of printed circuit board is Austrian Paul Luoaisile (Paul Eisler), he used printed circuit boards in a radio device in 1936. In 1943, Most of Americans using the technology within the military radio. In 1948, the United States formally recognized the invention for commercial purposes. Since the mid-50s of the 20th century, printed circuit board technology began to be widely adopted. Before the appearance of the printed circuit board, electronic components are to rely on the interconnection between the wire and direct connections to achieve. Now, the circuit bread board is as an effective experimental tool exists, printed circuit board in the electronics industry has occupied the position of absolute rule.
Design:
Printed circuit board design is based on circuit picture shows the basis for the circuit designer to achieve the functionality required. Printed circuit board design layout mainly refers to the need to consider the layout of the external connections, internal electronic components of the optimal layout, interconnect and via optimization of the layout, electromagnetic protection, heat dissipation and other factors. Good layout can save production costs, achieve good circuit performance and heat dissipation. Simple layout can be achieved by hand, require complex layout using computer-aided design (CAD) to achieve.
Advantage:
The main advantages of using PCB:
1. As the graphics with the repeatability (reproducibility) and consistency, reducing wiring and assembly errors, saving equipment maintenance, testing and inspection time;
2. Design can be standardized, which will help exchange PCB
3. Wiring density, small size, light weight, the miniaturization of electronic devices benefit;
4. Conducive to mechanization and automation of production and improve labor productivity and lower cost of electronic equipment. PCB manufacturing methods can be divided into minus method (Subtractive), and add method (Addition) The two major categories. Currently, large-scale industrial production or in less law-based method of corrosion of copper foil.

Circuit Board?
I am trying to find somebody that knows how to make circuit board and has the tools to actually make one.I have an idea for what could turn out to be a very big business venture.I am not asking for any money only the chance to work with somebody on this idea.There isn't anything like what I'm thinking of on the market and i know from round about questioning people that there is an intrest I would even venture to say 50 out of 50 people said they would be interested if they could get this thihng i am talking about.Idon't have any money to go to a company and have them put together something that i would be willing to work an and share any if any profit it might make.If any body knows af somebody interested please let me know where I might go to find people that might be. Thank you.
Are you trying to get a prototype board made? This could cost several hundred dollars. I know of a couple of companies that can do this. If you're serious, and have money to invest in a prototype, email me (click my profile).
