1.2 Invoking TINA PCB
To begin PCB design, press the button on TINA’s toolbar (the last one o the
right) or select the “PCB Design” command on the Tools menu. Set the parameters as
Select “Start New Project,” “Autoplacement,” and “Use board template.” With th
Browse button find and select the 2layer_A.tpt template file from TINA’s Template
folder. Using this file will ensure the proper settings for a double-sided PCB.
When starting with a TINA template, you are choosing the level of manufacturing
complexity of your project. The following three levels of manufacturing technology are
defined by the IPC-2221 generic standard:
Level A : General Design Complexity
Level B : Moderate Design Complexity
Level C : High Design Complexity
The template file specifies the number of layers, including their properties, system grid
size, autorouter settings, spacing and track width. The following templates are included
with PCB Designer:
In choosing a PCB template, you should take into consideration technology, density, and
To complete the set up, set the PCB size in inches or mm depending on the measurement
unit settings in the View/Options dialog of TINA.
Now that everything is set properly press the OK button and the PCB layout design will
appear with all the components automatically placed on the PCB board.
While all the parts and nets are placed, we need to adjust their positions for good
placement and easier routing. Click and drag the parts to the position as shown on the
figure below. (Find “opamp2 placed.tpc” to check your results.)
Press F4 to reach the Net Editor and set net routing width. First, click on “Modify all”
and enter 12.5 into “Track width” field. Then select power nets (Ground, VCC, -VCC)
and set their width to 25mil.
To automatically route the PCB, press the F5 button or select “Autoroute board”
command from the Tools menu. The following screen will appear:
To see of everything is route correctly press F7 or select DRC (Design Rule Check
from the Tools menu. The following message will appear:
To finish our first simple design, let’s add text to the silkscreen/assembly layer. Click the
T button on the toolbar and make the settings in the dialog that appears:
Enter the text into the empty upper field and press the OK button. The text will be
attached to the cursor. Move it to the location shown on the picture below and press the
left mouse button to place the text.
Finally, you can check your design in full 3D. Press F3 or select 3D View from the View
menu. After some calculation, the following window will appear.
You can rotate the 3D model to any direction by clicking with the mouse at any point.
Hold down the left button and move the mouse to shift the viewpoint. You can also
move the ”camera” forward or backward to set a large view showing the complete PCB or
to zoom in for more details. Use the right mouse button for this operation.
At this point, you will probably want to either print your design or create Gerber files for a
manufacturer. To print use Print… from File menu.
To obtain Gerber (RS-274X format) files to direct a photoplotter, choose Export
Gerber file from the File menu. (Various Gerber options can be changed using the
dialog for Gerber output settings under the Options menu.)
1.3 Advanced editing functions of TINA PCB’s Layout editor
In practice, you may need to do some editing using TINA PCB’s advanced editing
features. This is described through examples in the next section.
