Unable to get copper filled on top layer

[Sashvat]

Hi guys, I am using KiCAD for this project of mine. So I have a STM32F030R8T6 microcontroller and I made this board to make it breadboard friendly (a break out board) for prototyping, when I try to fill the top layer with copper, its not filling completely and only some places get filled. If you see, the bottom layer is full but the top layer is not completely filled with copper like the bottom layer. Let me know where I am going wrong.

Thank you

Not familiar with kicad but it's fairly obvious that the fill can't get into the clear areas. If you reduce the through hole size it may be able to get between the pads.

I was thinking of reducing the trace width, would it help?

See if there is a minimum width in the fill parameters.

The keep out area or the size of the gap between pins is too big, so the fill cannot get between the pins as they are touching. Modify that and it will fill the area in.

would it be a good idea to give this one for production?

do you mean the pins for the male header or the microcontrollers pins?

See this video. At around 13:00 minutes. John does a great job showing how to get up to speed with Kicad

Yup...copper fill clearance is set to large.

Go to your board house and find out the minimum line width and minimum clearance. You need good numbers.

I think this was meant for the
Anyway, I use 6-8 mills.

thanks all, I took it down to 0.001mm of clearance, it worked, I hope its fine?

I'd check with whoever is making the boards if they can handle such a small clearance.

PCB way or JLC PCB is my go to for getting the boards done, I'll keep doing some trial and error with the clearance.

JLC PCB

they can handle 0.003" traces and gaps but you are asking for 0.001mm (0.0000039"). You do realize that 0.001mm is one-micrometer, right?
