Hello!,
How I can improve this PAD L-shaped?
I put 2 oval pads, but remnants of copper. How can I improve it?
Best regards

Did you check with your fab house if they are OK with oval through holes?
0.6 mm milling diameter is not for the faint of heart 
Can you post a link to the datasheet for the connector please?
If I was you I would take artistic liberty and mill it all with the same diameter.
Is this for production or hobby?
In case of hobby I would do 0.8 mm milling.
As for the 3D viewer display glitch, donât worry, it shouldnât affect the outcome.
I would be wary on those âsidewayâ slots though, their position in your footprint isnât centered on the large one as itâs given in the drawingâŚ

as @Joan_Sparky pointed out 3d-viewer doesnât show the real pcb drill resultâŚ
you can have a look at kicad StepUp tools and open your footprint in FreeCAD
if you hide pads and pth you can display the pcb as the real result after the drilling
Olimex, to avoid oval drills, that some fab donât accept or extra charge for, normally makes standard drills, one beside the other
i.e. if you open their latest board

and if you look at the HDMI1 connector you can have a better idea of that
Also PWR1 has the same drill modality

Yeah, but with overlapping drill-holes they will like that even less, especially at those diameters as the drill is prone to breaking under these circumstances⌠a milling bit is the better choice then as itâs made for this kind of load.
In the end the fab house needs to decide on that one anyway - I would definitely avoid different diameters there though as it means tool changes and re-approach of the tool with all kinds of tolerances⌠make them all 0.8 or 0.7 mm diameter and call it a day.
I think 0.8 mm is the smallest you get without special prices from a Chinese fab.

Olimex make their own PCBs, so they will have chosen a method suitable for them.
In general when it comes to slots and routing, it seems you need to consult the board house you intend to use as to what method they prefer. I know some of the cheap Chinese fabs prohibit multiple drill hits.

Trust only the gerber output.
And take in account the other hints for other posts.
Not, Iâll ask him tomorrow.
Sorry for the DS.
For prototype of radio modem of 500mW NarrowBand.
Thanks very much!

I see it. Thanks!
@bobc, @kammutierspule, Thanks!
Sorry for posting offtopic in old thread, but could you please share your 3D model of the connector? Where did you get it? Did you make it?
Thank you! I only found a 3D model request form on their website, and I guess when they send it to me, itâs going to be in STEP format, while KiCAD only supports X3D models.
Kicad (v4.0.x) mainly supports wrl.
But there is kicad stepup a freecad extension to create correctly scaled and colored wrl files from step files.
