PCB Design With Simple and Easy Steps




Introduction: PCB Design With Simple and Easy Steps

About: working as a college professor.


Its very useful and easy tutorial for those who want to learn PCB design

come lets start


Multisim:- It is a schematic capture and simulation application that assists you in carrying out the major steps in the circuit design flow. Multisim can be used for both analog and digital circuits and also includes mixed analog/digital simulation capability, and microcontroller co-simulation. Simulating the circuits before building them, catches errors early in the design flow, saving time and money. Ultiboard:- Ultiboard is fed from Multisim, is used to design printed circuit boards, perform certain basic mechanical CAD operations, and prepare them for manufacturing. Ultiboard also provides automated parts placement and layout

Step 2: STEP 1

In this exercise, you will place and wire the components in the circuit shown below

Step 3: STEP 2

Double click on the component and select ‘Edit footprint’.

Step 4: STEP 3

Then click on ‘Select from Data base’.

Now Select the footprint [RES1300 – 7000C2500], and click [Select].

Step 5: STEP 4

Trannsfer the schematic design to Ultiboard 10 by selecting Transfer » Transfer to Ultiboard 10.

Step 6: STEP 5

Select [Transfer] / [Transfer to Ultiboard 10]. A standard Windows Save As dialog box appears. Specify the name and location of the files to be created and click [Save]. Multisim creates files that can then be loaded into Ultiboard.
Enter the desired parameters and click [OK].

Step 7: STEP 6

After click [OK] this window will pop-up

Step 8: STEP 7

The following dialog should appear after select [Transfer] / [Transfer to Ultiboard 10]. Change the width to 10 mils, and the clearance to 10 mils. Click [OK] to close dialog box.

Step 9: STEP 8

Make sure all fields are selected in Import Netlist Action selection and click [OK].

Step 10: STEP 9

A board outline (a yellow rectangular) is placed on the workplace with the components (above the board outline) ready to be placed

Step 11: STEP 10

Working with the Board Outline. Right-click the edge of yellow rectangle and select Properties from the menu. This launch a Rectangular Properties dialog.

Step 12: STEP 11

Under the rectangular tab, set the Units to mil, the Width to 1000 and the Height to 900. Click OK to close the dialog box and the board outline becomes much smaller

Step 13: STEP 12

Now u can see the board outline becomes much smaller

Step 14: STEP 13

Select the components and drag them until they are above the board outline.
Select ‘view’ and click on ‘3D preview’.

Step 15: STEP 14

Now you can see the 3D view dialog box

Step 16: STEP 15

Select ‘Auto route’ and then select ‘Start/Resume Auto router’

Step 17: STEP 16

Now the circuit become auto routed.

Step 18: STEP 17

Place the components in preferred location and then check the design rule.

Step 19: STEP 18

Select ‘start auto router trace optimisation’

Step 20: STEP 19

After ‘start auto router trace optimisation’ the board will appear like the figure shown in below

Step 21: STEP 20

Ultiboard Configuration. Select [Options] >> [Global Preferences], and then select the General Settings tab. Make sure it matches below settings.

Step 22: STEP 21

Select PCB Design tab and make sure you choose Auto trace narrowing and Auto add teardrop. Click OK to close the dialog box.

Step 23: STEP 22

Select [Options] >> [PCB Properties], and then go to Copper Layers tab. Change Board thickness to 59.00 mil. *Refer to LPKF’s PCB board.

Step 24: STEP 23

Next, go to the Pad/Vias tab, and modify the settings as shown. How to calculate annular ring?
For example, a 50 mil drill hole (radius of 25 mils) with a relative value of .6 (60%) will create an annular ring of 15 mils (60% of 25 mils).

Step 25: STEP 24

Go to Design Rules tab, and the “Use multiple clearances” checkbox must be selected. Otherwise, only clearance to traces will be operational. Set the “Clearance to Traces” parameter to 40.000000 mils; “Clearance to Pads”, “Clearances to Vias” and Clearance to” Copper Areas” parameters to 32.000000 mils. Click OK to close dialog box.

Step 26: STEP 25

Power and Ground Planes. Select [Place] >> [Power plane]. Select net 0 for Copper Bottom Layer. Click [OK] to close the dialog box. The bottom layer fills in red color plane.

Step 27: STEP 26

Now the board will appear like below circuit

Step 28: STEP 27

Now select ‘File’» ‘Print’ and then this dialog window will pop-up

Step 29: STEP 28

Select ‘copper top’ alone then select ‘preview’.

Select ‘Tool’» view 3D. Then select full screen option.
