Printed circuit board prototypes can be made from different materials depending on which person created the prototype. One example on Pic Projects describes a prototype made from photo resist boards, art film, UV light boxes, and other materials.
PCB Printed circuit boards are made using copper foil, laminates, resign stage cloth and copper-clad laminates. These items are generally purchased direct from manufacturers.
Flexible printed circuits are used so that boards can be conformed to a particular shape. They are often used in computer keyboards, cameras, calculators, and cellular phones.

Resistors are tiny devices on circuit boards. Prices should range but should not be expensive but dependent on the materials used and the nature of conductivity.

Circuit boards are not dangerous to use and they are not some type of skateboard. There are tons of varieties of circuit boards for different things you are trying to control. You'd need to ask a more specific answer since there are so many types.
Etching copper circuit boards.
Reflow ovens are used to create circuit boards and other electronics. They are used mainly for reflow soldering for the surface mount type of electronic components.
it means 470 resistor and is used in many circuit boards.
That is the general color for PCBs (printed circuit boards) back then, as the general process for making circuit boards is having a board coated in copper etched in a specific pattern (using a etching chemical to eat away the copper) obtained from the engineer that designed the circuit. Nowadays computer system boards do not look like the traditional green as manufacturers may shift to slightly different methods of producing their boards.
Depends on the material it's constructed from, the application for which it's being used and the atmospherics to which it's exposed. I have printed circuit boards from the very first model of an RCA transistor radio made in 1957 and the circuit board as well as the electronics still work.
It is possible to look at prototypes of commonly used circuit boards at Thomas Net, Analog Static, EI Connect, Wise Geek, How It Works, and e-tool Smith.
That is just the conventional color of the insulating varnish "mask" used to protect the board. It could be a different color, but green was selected as it contrasts well with copper traces allowing them to be seen through the "mask". Up until the late 1950's, circuit boards were usually brown in color. The brown boards had no "mask" on them, the traces were protected with solder dip. Brown is the color of the paper-epoxy or paper-phenolic board material used.

A computer circuit board is used to connect the electronic components and circuits inside of a computer. Computer circuit boards are composed of laminates, copper clad laminates, and copper foil.
