Very little. Some gold-plating is barely a tenth of a micro-metre (0.000005 inches) thick, and when you look at the small area that's actually plated... It would be extremely unusual to find a circuit board with anywhere near a tenth of a gram (0.0035 ounces) of gold on it.
In the 39 Clues series, the "circuit board" clue refers to a specific puzzle related to the activities of a mad scientist character. To solve it, players must interpret the circuit board's connections and components, often involving logic or pattern recognition. The answer typically reveals information about the scientist's experiments or intentions, linking back to the overarching narrative of the series. Players need to combine their clues and knowledge from previous books to arrive at the correct solution.
SHORT CIRCUIT AND OVERLOADElectricity energy is supplied into homes by pairs of insulated copper wires placed on walls and ceilings.Not much heat is produced in the wires because copper has low resistivity.However,if the current is very large,the wires may become hot enough to melt or burn the insulation and start a fire.This large current may be caused either by a short circuit or by overloading the circuit. 2. CIRCUIT PROTECTORThe panel board in your home where electrical energy is distributed through different circuits contains fuses or has a circuit breaker system.Each circuit branching out from the panel is connected in series to a fuse or circuit breaker.Fuse and circuit breaker are safety devices that brake the circuit whenever overload or short occurs by breaking the circuit of fire are prevented.

Low-voltage load centers typically have electrically operated draw-out type air circuit breaker units while panelboards typically have mold-case air circuit breakers or fused disconnect switchgear contained in steel enclosures.
Depends. If it is gold plated, it is negligible. Best to gather alot of plated pins & fingers & eBay them or sell them to a recovery service. (eBay is usually best) If it is a Gold pin that (from the large end) appears to be a thick layer of gold around a thin steel or aluminum color center, that pin could be as much as 2/3 gold! Alot of pins can = alot of gold. Hope this helps!
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.

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.
