What is the use of computer boards?
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.
What does 470R mean?
it means 470 resistor and is used in many circuit boards.
What were computers like in 1909?
There weren't any, at least not technically computers. There might have been circuit boards.
What is function of the notch on a integrated circuit?
Notches on integrated circuit chips - and circuit boards - serve various purposes:to ensure that the ic chip board is fitted the right way round in its holder or slotto ensure that only the correct ics and circuit boards that are compatible with the electronic equipment are installed into the slot(s) provided. (For example on a computer's mother board.)Example:200-pin memory modules cannot be installed into 204-pin memory sockets because a notch would physically prevent it from being plugged in.
How does a circuit board work?
A circuit board or more precisely a printed circuit board (PCB) is a mechanical structure that provides support for mounting electronics and electrical components and connecting them with conducting traces or wires. PCBs are designed to perform a specific electrical or logical function. So what and how a circuit works will depend on its design. e.g. a circuit board in a TV processes audio/video TV signals. An audio amplifier circuit board amplifies and makes audio signals louder. Similarly various circuit boards in a Personal Computer perform different functions e.g. PC mother board, TV tuner card, USB/Firewire Card, Graphics cards are all circuit boards and perform different tasks. All of them need power (typically a DC voltage) for various components and circuits to work.
What are the industrial uses of gold?
electrical connections and circuit boards. gold conducts electricity very efficiently and does not corrode.
Where is the gold located on the computer boards?
It was once used in all the circuit boards such as the motherboard. However this was expensive, and it's rare to find any gold in modern computer electronics.
How to extract gold off printed circuit boards?
grind up the circuit board and melt the board. it will stink so go outside
What country can you get circuit board?
Taiwan has good quality circuit boards. So, you can get circuit boards from there.SHARAN
How much gold plating in a computer?
for one thousand pounds of circuit boards you can expect at today's rates to get ~$10,000 after it is refined
What do you use neurotic acid for?
For gold extraction out of electronic equipment in circuit boards
How is mobile phone gold extracted?
The old circuit boards are simply melted in a furnace. The gold and other metals sink, while the plastics and other products float to the top as 'slag'.
Where can someone find a printed circuit board design online?
You can find a printed circuit board design online in some blogs or message boards that are interested in designing circuit boards. You can also find some designs on websites that sell kits and circuit boards.
Why do you use green masking and not any other ordinary color in printed circuit boards?
Green, Red, Purple, Gold, Blue are all used.
Are circuit boards dangerous to be used?
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.
Circuit boards that provide more memory or control peripheral devices are called?
Expansion Boards
What percentage of electronic connectors sold in the U.S. were printed circuit boards?
About one-third of electronic connectors sold in the United States are printed circuit boards.
