By Cyrielle Marjolaine. Diagram. Publised at Sunday, November 19th 2017, 23:35:54 PM. A PCB Layout is the resulting design from taking a schematic with specific components and determining how they will physically be laid out on a printed circuit board. To produce a PCB Layout, you must know the connections of components, component sizes (footprints), and a myriad of other properties (such as current, frequencies, emissions, reflections, high voltage gaps, safety considerations, manufacturing tolerances, etc.).

Some are used to limit LED current, and some are used on inputs (like the button and switch circuits) to both limit the currents flowing to the main chip, and to help protect against electrostatic discharge (or ESD – more on this topic later). The resistors on the Digilent boards, like most resistors used in digital systems, are physically small because they will not encounter large voltages or currents. For these smaller resistors, the resistor value in Ohms is printed in microscopic numbers on the resistor body, not visible to the naked eye.

For dynamic signals, the transfer function cannot in general be described simply. However, if the input is a sinusoidal signal then the output must also be a sinusoidal signal with the same frequency but possibly a different amplitude and phase. In other words, a linear system can only modify the amplitude and phase of a sinusoidal input.

A reliable way to verify the identity of the terminals is using a multimeter to figure out the forward current direction. On the resistance setting, Ω\OmegaΩ, the meter puts a small voltage on its test leads (this is why an ohm meter needs a battery). You use that small voltage to see which way current flows.

If you apply a negative voltage to a diode, so the −-−cathode terminal is higher voltage than the +++anode terminal, this puts us on the left side of the iii-vvv curve. We say the diode is reverse biased. In the reverse direction, the current is very close to zero, just ever so slightly negative.

By Alix Loane. Circuit. Published at Thursday, October 26th 2017, 18:28:29 PM. Double-layer or double-sided PCBs have a base material with a thin layer of conductive metal, like copper, applied to both sides of the board. Holes drilled through the board allow circuits on one side of the board to connect to circuits on the other.

By Sasha Sara. Circuit. Published at Wednesday, October 25th 2017, 18:12:08 PM. These are commonly termed as IC’s. They are usually in form of chips and microchips. This is a set of multiple electronic circuits on a small semiconductor device (normally silicon). With the advancement of technology, these IC’s prove to be extremely beneficial. They are present in any electronic device you can name. From computers, mobiles to other digital appliances you have multiple IC’s present in them. Their main components are a combination of Diodes, transistors and microprocessors. The microprocessors provide memory to the device. With the help of the microprocessor the electronic devices can perform logical or protocol applications.

By Sasha Sara. Diagram. Published at Tuesday, October 24th 2017, 18:09:15 PM. The unloaded PCB appears green because thin sheets of green plastic have been applied to both sides (otherwise the PCB would appear pale yellow). Called solder masks, these sheets cover all exposed metal other than the component pads and holes so that errant solder can not inadvertently short (or electrically connect) the printed wires. All metal surfaces other than the exposed pads and holes (i.e., the wires) are underneath the solder mask. Not infrequently, blue or even red solder masks are used.
