Using TINA 7, you’ve captured the schematic of your circuit and refined the design. It’s
time to make a prototype of the circuit or to manufacture it. It’s good to know that you
can continue the process still using TINA 7 Design Suite (and later versions), since
PCB design is now an integral part of the program.
Let’s learn how to design a PCB by working through a few examples.
Note that the different phases of the presented design examples have been saved in
the TINA’s Examples/PCB directory using the following naming conventions:
If you save your versions of these demo examples, be careful not to overwrite the
original files TINA installed.
1.1 Setting and checking footprint names
As a first example, open the opamp2.tsc project from TINA’s Examples/PCB
folder. The following schematic will appear:
To achieve an accurate PCB design, one that is easy to build, every part in your schematic
must have a physical representation with exact physical size. This is realized through
so-called footprints: drawings showing the outline and the pins of the parts.
The footprint naming convention in TINA Pro uses as a starting point the IPC-SM-
782A (Surface Mount Design and Land Pattern Standard) and the JEDEC standard
JESD30C (Descriptive Designation System for Semiconductor-Device Packages, see
http://www.jedec.org/download/search/jesd30c.pdf.). However, the libraries do not
conform to any given set of industry or manufacturer standards because standards have
difficulty keeping up to date when technology changes faster than the standards.
Generally, standards mirror a fixed set of data at a point in time, while new
manufacturing capabilities lead to ever-smaller new footprints with more and more pins.
We have already assigned default footprint names to all parts that represent real
Note that some parts used for theoretical investigations, controlled sources, for example, do
not represent real physical parts and cannot be placed on a PCB. If your desig contains
such components, you should replace them with real physical parts.
Of course there is no guarantee that the default physical packages of TINA’s parts are the
same as needed by your design.
There are two ways to check this.
1) You can use TINA’s “Footprint name editor”, which you can invoke from TINA’s
Tools menu. In this dialog you can see all of TINA’s components and their
corresponding footprint names.
Select from the available footprint names by clicking on the footprint name fields. In the
dialog box, components with no footprint name association are denoted by red characters
and by “???” in the footprint name field.
2) The second way to examine the assigned footprints is to double-click on each part and
check the Footprint Name in the component property dialog that appears.
You can also click the button in the Footprint Name line to invoke the “PCB
information” dialog. This allows you to select from the available footprint names on the
Footprint list. Here you can also find and display the 3D view of the parts on the list.
When you find the footprint you seek, click on it and press OK. This will return you to
the component property dialog with the selected footprint name in the Footprint name
line. To confirm the change, press OK on the component property dialog again.
If you don’t find the footprint you want, you can create a new one. Start by pressing the
Add button of the “PCB information” dialog. Of course, it’s not enough to just add a
footprint name in this dialog–you must also add the corresponding footprint to PCB’s
footprint library. For details, see chapter 6 – Making your own schematic symbols
and footprints – of the Quick Start Manual.
When you’re done, check the 2D/3D shape by clicking the 2D/3D view button or the F6
key. Unless a component is only meaningful for analysis, it will have a 3D view. If the
physical part association is OK, we can begin the PCB layout design.
