But what is PCB? Why we are using this PCB? We want to know about all these things as a electronic engineer. This is a circuit board with printed copper layout connections. The two examples are shown in below.
In dotted PCB board only dots are available. According to our requirement we can place or insert the components in those holes and attach the components with wires and soldering lid. In this dotted PCB we can make the circuit as out wish but it is very hard to design. There are so many difficulties are there.
Those are connecting the proper pins, avoiding shot connections and etc. Coming to the layout PCB this is simple to design. It is simple to design, take less time to design, no shortages, looking nice and perfect. Now we can discuss about PCB designing software. There are so many PCB designing softwares available. Apart from remaining Proteus is different. Proteus is design suit and PCB layout designing software. In Proteus we can design any circuit and simulate the circuit and make PCB layout for that circuit.
Introduction to Proteus: This is a powerful and integrated development environment. Tools in this suit are very easy to use and these tools are very useful in education and professional PCB designing. Up to know we have discussed about the basics and software description.
Now we are entering into the designing section. Run the ISIS professional program by clicking the icon on the desktop, then this splash screen will appear.
Screenshot of Launch Window of Proteus Design Suite Next, a work space with interface buttons for designing circuit will appear as shown in figure below. Note that there is a blue rectangular line in the workspace; make sure that whole circuit is designed inside the rectangular space.
Let us take one example is designing of 38 kHz frequency generator by using timer IC. The circuit diagram is shown in below image. So select the components from library. Then one window will open that shown in below.
Screenshot of Device Selector on Proteus There is another way to select the components. In work space left side there is a tool bar. In that tool bar click the component mode button or pick from library. Screenshot of Component Mode Button on Proteus Select the all components from library, that components are added to devices list.
Click on the device and change the angle of the device by using rotate buttons. Then click in the work space then the selected component is placed in work space. Place all the devices in work space and put the curser at the component pin end then draw the connections with that pen symbol.
Connect all the components according to circuit then that designed circuit is show in below image. Screenshot of Sample Circuit designed on Proteus If any modifications want to do to the component place the mouse point and click on right button then option window will open.
That is shown in below figure. Screenshot of circuit modifications on Proteus After completion of designing save with some mane and debug it.
This is virtual simulation means without making circuit we can see the result in virtually through this software and we can design the PCB layout to our required circuit with this software. By using this we can easily develop the PCB layout. After simulation save the circuit designing and click on tools then select netlist to ARES. Then a window will open with list of component packages. That is shown in below image. Screenshot of Tools Menu on Proteus Fig. Screenshot of Work Space on Proteus Then next step is creating a board edge by selecting 2D graphics box mode.
Next click on the select layer at bottom left corner and select the board edge option. The image is shown in below figure. Screenshot of 2D graphics Box on Proteus Then next click on work space then a green line will appear. With that draw a box and click again once. Then the box is fixed and turn into yellow color layout. This box is same like in above ISIS professional blue line. The circuit should be inside of the yellow box.
If the circuit is more complex and big in size, the there is a chance to expand the box by clicking on the select mode. Then next click on the component name and change the angle of the component by using rotation arrow options if required. Then place the component on the work space.
After adding the all components to the work space, arrange the position of the components properly in the workspace. To move component one place to another place click on selection mode and click on component then it change color with white and hold the component and moved to required place within the yellow box.
After placing the all components in correct position, next thing is tracking. Tracking means establishing the connection between the components with copper layer. When we click the button C or E immediately a window will open. Select the width of the track from given list. It is better to select between 25, At that time track width in case less than 25, there is a chance of occur cuts in tracks.
The less width is useful in computer based PCB layering. So the width should be greater than My suggestion is the width should be Connection representation in green line and yellow line shows the direction. After setting the track width click at the component one end with pen and follow the green line. When two components are successfully connected then green line will removed automatically. In single layer PCB components are placed at one side and connections tracking done in another side.
Coming to duel layer PCB, tracking is done in two sides and components are placed in two sides also. In this type mostly SMD components are used. In this two are top and bottom layers and remaining all are inner layers. In Proteus we can design up to 16 layers PCB. One is top layer, another one is bottom layer and remaining all are inner layers. The layer selection in Proteus is at left down corner. Each layer will represent in different color. For example bottom layer represented in blue color, top layer represented in red and inner layers are represented in different colors.
The image shown in below figure. Screenshot of Layout designing on Proteus In the above image, it shows that track is placed between R pin and RVpin. Another thing is placing the track from 6th pin to 3rd pin. The direction is indicating in white arrow mark. Connection is indicating in green line and blue line indicates the track.
If any contact errors occurred while tracking, those are represented in red circles and the image shown in below figure. Screenshot of PCB Layout on Proteus In the above image red color represented circles are errors occurred while tracking.
To avoid such errors change the track path. Like this arrange the tracks between the all pins without errors. If you are planning for duel layer PCB, there is short cut for changing the track layers from one layer to another that is press the mouse left button two times immediately turned into another layer. In above image there is an orange circle.
There is an advantage in Proteus. That is auto-router. This is special tool to arrange tracks automatically without errors. But this tool creates duel layer PCB. When we select this tool, automatically shape based auto router window will open. This window having the execution mode, design rules and grid width changing options. By changing all options according to our requirement and click the button begin routing automatically routing will start.
Screenshot of Auto Router on Proteus In above second image red tracks indicate top copper and blue tracks indicate bottom tracks.
Step 1: Installing Proteus 8.0
Schematic capture in the Proteus Design Suite is used for both the simulation of designs and as the design phase of a PCB. Proteus is a simulation and design software tool developed by Labcenter Electronics for Electrical · and Electronic circuit design. It also possess. Circuit Diagram – Interfacing GSM Module Using Proteus By using this simulation feature the designer can develop the systems within the software and test all.
PCB Layout Design with Proteus
Step 6: This is the size of your PCB you can change it by hoovering your mouse pointer at any corner off this Block. As I have also changed it after completing the design. Now click on the small diode icon which indicate that component lists.
This Proteus software suite containing schematic and simulation with PCB designing. ISIS is the software used to draw schematic and simulate the circuits in real time.

In my case the location of the Proteus library is, C drive>Program Files> Labcenter Electronics>Proteus 7 Professional>mjnoxj.me that you will find arduino. I will tell you process of designing the printed circuit board in Proteus PCB Design in Proteus AND how to convert schematic to pcb layout in.
