What are the lines on a circuit board for?
These copper lines (known as traces) allow electrical charge to flow through the PCB, providing power to the different components that are situated systematically on the board. The copper traces function in the place of wires, guiding the electricity to the correct destination.
What are the white lines on a circuit board?
The lines (referred to as traces) connect various electronic components on a Printed Circuit Board (PCB) in a way that was specified by an Electronic Engineer’s (EE) design, generally done on Electronic Computer Aided Design (E-CAD).
What is a circuit board and how does it work?
Simply speaking, a circuit board is a printed board that has electrically conductive pathways called ‘traces’ that connects electronic components to each other. Circuit boards are one of the most important inventions that heralded the onset of electronic technology.
What are the green lines on a circuit board?
The green stuff on circuit boards is a green solder also known as the solder resist layer, which is a kind of paint layer, which provides a permanent protective coating for PCB copper lines, and can prevent the bridging of solder between conductors, thus preventing short circuit.
How can you tell if a circuit board is positive or negative?
Sometimes it’s easiest to just use a multimeter to test for polarity. Turn the multimeter to the diode setting (usually indicated by a diode symbol), and touch each probe to one of the LED terminals. If the LED lights up, the positive probe is touching the anode, and the negative probe is touching the cathode.
What is the function of circuit board in hard disk?
A hard drive’s Printed Circuit Board, or PCB, allows electricity to pass between various components that allow the hard drive to function. If you have ever handled a hard drive, you may recognize the PCB as the green or blue board on the bottom of the device.
How does electricity work in a computer?
Powering on the computer When you first press the power button, the computer sends a signal to the computer power supply, which converts the AC (alternating current) to DC (direct current). This power supplies the computer and its components with the proper amount of voltage and electricity.
Why is circuit board green?
But, why are printed circuit boards green? It is due to the solder mask, which protects the copper circuits printed on the fibre glass core to prevent short circuits, soldering errors, etc. The colour of the solder mask gives the board its appearance.
Why IC is black in Colour?
the black color is carbon. carbon absorbs radiation, in particular UV radiation which would damage the delicate internal circuits. carbon is also a conductor of heat. this helps move heat away from the internal workings and dissipate through the case.
