zero but there is probably copper
grind up the circuit board and melt the board. it will stink so go outside
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 main component in a cell phone that contains gold is the circuit board. Gold is used in the connectors and wiring of the circuit board due to its excellent conductivity and resistance to corrosion. Recycling old cell phones can help recover valuable materials like gold.
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.
Gold is a very good conductor of electricity due to its high electrical conductivity. This is why gold is commonly used in electronics, such as in connectors and circuit board traces.
rigid-flex circuit board

mother is the main circuit board of the computer on which all the hardware devices are connected to the supply while circuit board is the circuit which a particular device use and is connected to motherboard
A circuit board It is a board containing devices passive and/or active that can be installed on a system to make it whole. Usualy refered a PCB OR PRINTED CIRCUIT BOARD.its a board of circuits
