gold is applied as a micro-thin layer over the entirety of the circuits to protect them from oxidation.
Gold is not on "the entirety" of the board, just the connector contacts. The rest of the copper traces can either be protected with tin (its cheaper) and/or a "mask" of green insulating varnish.
Circuit board kits vary in cost depending on what type of circuit board you are building. You can buy circuit board kits from Amazon starting at $35.00. There are many other options out there as well.
The motherboard aka mainboard
Design of a circuit board starts with a layout of what you require the circuit to do. Plug and component placement depend on where the board will be mounted and the environment that the board will be used in.
The average cost of these circuit board prototypes are they are a lots more than me and you got all together and it takes a special person that can afford these type of circuit board prototypes.
Yes
zero but there is probably copper
grind up the circuit board and melt the board. it will stink so go outside
in the back
There are several circuit boards in that vehicle. Need to know which one you are looking for.
No, no parts of cell phones or mobile phones are made of iron. The metals used in these phones are:Aluminium (covers, frames, battery, circuit board.)Antimony (covers)Barium (circuit board)Beryllium (connectors)Cobalt (lithium-ion batteries)Copper (circuit boards, wires, connectors, batteries)Chromium (cover, case)Gallium (LED light)Gold (electronic parts, connectors, circuit board)Indium (screen)Lead (circuit board)Manganese (circuit board, case)Nickel (battery)Palladium (circuit board)Platinum (circuit board)Ruthenium (circuit board)Silver (circuit board)Iron is heavy, gets warm quickly and reacts with moisture in the air leading to rust, so iron is not a suitable metal for a phone.
The main circuit board of the computer is the motherboard.
rigid-flex circuit board
is the main printed circuit board (PCB)
behind the ignition switch on the circuit board. there are two fuses there

It is located inside the ECU and its small and soldered to the circuit board.
