Introduction to the fundamentals of printed circuit board design using Proteus software for designing PCBs.
A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate.
Contents and Overview In this course you will learn how to design your own PCB using Proteus and learn how to make the PCB at your home using common tools that are most likely to be found at any home like iron, soldering iron …etc.
In 24 lectures this course will make you a confident PCB designer and maker using Proteus software.
After this course you will be able to design and make professional PCBs that work from the first time.
Course Goals :
A printed circuit board (PCB) mechanically supports and electrically connectsusing tracks, pads and other features from copper sheets onto a . Components (e.g. , or active devices) are generally on the PCB. Advanced PCBs may contain components embedded in the substrate.
PCBs can be single sided (one copper layer), double sided (two copper layers) or multi-layer (outer and inner layers). Conductors on different layers are connected with. Multi-layer PCBs allow for much higher component density.
is the primary insulating substrate. A basic building block of the PCB is an FR-4 panel with a thin layer of copper foil laminated to one or both sides. In multi-layer boards multiple layers of material are laminated together.
PCB making steps:
The Proteus Design Suite is an
several overseas sales channels. The software runs on the operating system.
Schematic capture in the Proteus Design Suite is used for both the simulation of designs and as the design phase of a PCB layout project. It is therefore a core component and is included with all product configurations.
The 555 timer IC is an(chip) used in a variety of , pulse generation, and applications. The 555 can be used to provide time delays, as an , and as a .
We will use it in astable mode to turn on/off a LED
The term "copper pour" refers to an area on afilled with . Copper pour is commonly used to create a . Another reason for using copper pour is to reduce the amount of fluid used during manufacturing.
Bridges are your last resort when you can't make a trace between two pads without making a short circuit, So you use a wire and two vias instead.
The 3D Visualization module allows the board under development to be viewed in 3D together with a semi-transparent height plane that represents the boards enclosure.output can then be used to transfer to mechanical CAD software such as or for accurate mounting and positioning of the board.
of . Originally it was literally a bread board, a polished piece of wood used for slicing bread. In the 1970s the solderless breadboard (AKA plugboard, a terminal array board) became available and nowadays the term "breadboard" is commonly used to refer to these.
Because the solderless breadboard does not require, it is reusable. This makes it easy to use for creating temporary prototypes and experimenting with circuit design. For this reason, solderless breadboards are also extremely popular with students and in technological education. Older breadboard types did not have this property. A ( ) and similar prototyping , which are used to build semi-permanent soldered prototypes or one-offs, cannot easily be reused. A variety of electronic systems may be prototyped by using breadboards, from small analog and digital circuits to complete (CPUs).
Using a laser printer, print the PCB design on a toner transfer paper -glossy paper-.
Using an iron apply some heat on the glossy paper for 2-3 minutes and after that soak the PCB in water.
Then Take the paper away from the PCB and you will notice that the ink has moved to the PCB from the paper.
Using FeCl3 because from the reaction equation of FeCl3 with Cu(copper) we will notice that the exposed copper reacts with the acid according to this equation: Cu+FeCl3=CuCl3+Fe
And after this step all what we will have left of the copper sheet is the tracks which were covered by ink, because the acid didn't react with the ink.
Using an electric driller, I'm going to drill the PCB in the component's places -pads- using 3 different drill bits.
To Protect our power supply from a heavy current, we gonna need a 0.5 amper fuse connected in series before the transformer's 220VAC input wire.
Also a resistor-led combination is going to be used to act as an indicator to show when the power supply is on.
