wha tis a printed circuit board?

Question

is a printed circuit board the same as electronic paper? I am trying to make a prototype of an electronic paper, and when i typed in electronic paper prototype, it came up with a site on how to make a printed circuit board with photopaper, water, and an iron.

Answer 1

A printed circuit board is one in which the conductors are plated onto a printed pattern (or etched away from a plated coating by following a printed pattern.) Until fairly recently, all printed circuit boards were rigid - about 1/16th inch (1.5 mm) thick with circuits on one or both sides. You will find one in virtually anything electronic - like the computer mother board and daughter boards.
Several years ago, people began making flexible printed circuits where the support was much thinner (0.1 mm) and could be bent to connect two rigid boards or fit in a confined space, but it was still plated or etched.
Recently, people have been trying to make circuits that could literally be printed - not plated, because it would be cheaper and because it would permit making shapes and then folding them to fit inside containers with sharper folds than thin flexed mount permits. One of the things that makes this possible is surface mounting of chips - they are so small.
The site you came up with is discussing how to make a mask to etch the overall plated prototyping board.

Answer 2

a printed circuit board is one where the parts are embedded in the board, which is made out of fiberglass, and the connections between them are embedded too. soldering is more difficult and take care not to short circuit parts and be careful not to melt the board, or other plastic parts. newer boards are not hand sodered, so you need to be faster because the soder is much thinner (they use what is called a "soder wave" where soder flows over the entire board, but is stopped only where they want it to) a multimeter is essential in electronics...Fluke is an excelland brand. also, if you have the money an ocilliscope is helpful when dealing with frequency related electronics.
