Introduction: Mount a DIP As a SMD on PCB

Picture of Mount a DIP As a SMD on PCB

I don't like drilling the PCB.

So, I always mount a DIP chip as a SMD chip with arranged IC socket.

Step 1:

Picture of

I use KiCad to make arranged footpattern.

Step 2:

Picture of

Load footprint.

Step 3:

Picture of

In this Instructable, I select DIP-16.

Step 4:

Picture of

Normal DIP-16 footpattern is like this.

Step 5:

Picture of

Select my own library for arranged footpatterns.

Step 6:

Picture of

I named my library 'sahara'.

Step 7:

Picture of

Save footpattern.

Step 8:

Picture of

Change the name.

Add 'SMD' to the new name is better.

I named 'DIP-16_DIP_to_SMD_socket" then file name is 'DIP-16_DIP_to_SMD_socket.kicad_mod.kicad_mod'.

Step 9:

Picture of

Close KiCad and open the 'your_footpattern.kicad_mod' in text editor.

In my case I open 'DIP-16_DIP_to_SMD_socket.kicad_mod'.

And replace strings as follows.

'thru_hole oval' --> 'smd rect'
'size 1.6 1.6' --> 'size 3 1.2'

'(drill 0.8)' --> ''

'layers *.Cu *.Mask F.SilkS' --> 'layers F.Cu F.Paste F.Mask'

'at 7.62' --> 'at 9.12'

'at 0' --> 'at -1.5'

Step 10:

Picture of

Open the footpattern in KiCad.

Then you will see this.

Step 11:

Picture of

PCB will be this.

Step 12:

Picture of

I need to arrange a IC socket.

Step 13:

Picture of

Cut the pins if they are too long.

Step 14:

Picture of

To use adhesive tape is my favorite way.

Step 15:

Picture of

It's all done.
