Free PCB Design. CAD Programms/Software to realize Printed Circuit Boards

Printed circuit board (PCB) is a component made of one or more layers of insulating material with electrical conductors.

I have collected a lot of material and soon it will begin a tutorial on the realisation about printed circuits.

"A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, or traces, etched from copper sheets laminated onto a non-conductive substrate. from Wikipedia Printed Circuit Board

There are plenty of sites on the web about PCB design, manufacture, application, reliability and companies.

Some videos about technology used for PCBs

If your are new or experienced PCB manufacturer you might find that using a reference design saves you time and money over trying to start from scrath with a new design yourself.

List of pcb magazines

There are two basic technologies associated with PCB fabrication: design and manufacture.

From basic physics it is known that currents circulating through materials dissipate some energy as heat.

The PCB industry consists of the companies that are in the business of designing, manufacturing and marketing printed circuit boards for all sorts of applications.

List of some of the most relevant places to go get an education on PCB

In the world of integrated electronics there are many competing priorities that need to be balance out in order for the designer to complete her task in time, under budget and meeting the requirements set from the beginning.

In order to understand what there can be time savings in the prototyping line, it’s necessary to understand how long it normally takes to get a prototype or First Article as they are known in the industry.

Given the complexity of electronic design, caused by the very fine features used and the need to very precisely align those features during manufacture and assemble, the need for computer aided design (CAD) software is imperative.

With some ingenuity, the right tools and lots of time and patience you can make your own PCBs.

In this world of quick easy communications sometimes the answer to a question is a query away knowing the right keywords and arming oneself with patience.

In the world of PCB making there are many areas that aren't so much a science as an art. Experience teaches many lessons.

For those of you lucky enough to have attended CeBIT2008 this past March in Hanover, you might have seen another series of GPS devices debut: the next two additions to the GPS lineup for Navigon Max series: 2100 and 2120.

The ever decreasing scale in microelectronics
Ever since the beginning of the microelectronics era there has been an eternal quest to reduce the characteristic features on the devices: some devices are now in qualification states on the sub 40nm gate oxide range for an scheduled commercial release towards the end of the year, and there are a lot of efforts in the sub 30nm range. But Moore’s Law, as this continuous drive to reduce sizes has come to be called, applies not only to the dimensions on the silicon.

As in any large, mature industry, the PCB industry has undergone significant evolution since its beginnings.
