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.

I use KiCad to make arranged footpattern.

Load footprint.

In this Instructable, I select DIP-16.

Normal DIP-16 footpattern is like this.

Select my own library for arranged footpatterns.

I named my library 'sahara'.

Save footpattern.

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'.

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'

Open the footpattern in KiCad.
Then you will see this.

PCB will be this.

I need to arrange a IC socket.

Cut the pins if they are too long.

![diptosmd_16.png](/proxy/?url=https://content.instructables.com/FZ7/MC2B/IN4TSAOH/FZ7MC2BIN4TSAOH.png&filename=diptosmd_16.png)
To use adhesive tape is my favorite way.

It's all done.
