CNC your custom usb slide-in PCB

So I had troubles properly naming title of this post. So as a short explanation my passionย also includes electronics ๐Ÿ™‚ and today I felt like playing with USB and RS232 ( reason for that will be obvious in one of later posts ).

Now in order to get this working I could most probably just get USB port and solder some cables into it but I think this would totally miss the idea of fun – especially in my case.

So where do we start ? We need to make a design ? No problemos ๐Ÿ™‚ using Eagle CADย I have created board schematic ( as in my case schematic for electronics is not needed ๐Ÿ™‚ )

The final design after a moment looked like this :

usbslider_01

 

So that was the easy part right ? Well yes ๐Ÿ™‚ However I do not forget that “sharing is caring” thats why you can download the project here

 

Ok so how do we get our project from digital world to our matrix ๐Ÿ™‚ ? There are several available methods :

  • Chemical etching
  • UV
  • CNC
  • Order your PCB at professional services

 

In my experience I have already been through chemical etching and though it works nice – yeah….. at certain point you get tired of all that action you need to execute . UV I have not yet played with ( but it also includes chemical toys ). Professional services is also not an option as this project is so small and I need it kinda … now ๐Ÿ™‚ so we are left with cool one …. CNC

Now with help of a bit of machine software and some PCB material I got the board ready in like 7 minutes. Machine is capable of faster operations but with PCB I would be risking damage to reallllyyyyy small drill bits ( talking from expensive experience here ๐Ÿ™ ) so thats perfectly fine with me. After machine was done I was presented with the following view ๐Ÿ™‚

hey ya! That is what I wanted ๐Ÿ™‚ However for next version I will need to ditch that outline margin as it was nice enough to connect all points of my board which for USB is not so good !

From there only a bit of soldering and some hot tube to isolate remains and we got this :

As it may not look sooooo super PRO ๐Ÿ™‚ but this is a POC prototype to make sure when I need more and order from professional services I get exactly what I expect.

 

If you are using CNC for PCB – leave a comment – interested in yourย approach
