I have designed a microcontroller and am having issues with via sizes and trace widths and whether or not i can make it smaller…
i am working on this for a senior design project and it is open source, so anyone can use it (students, hobbyists, etc) …any help would be appreciated so we can get this board made and start working on some robots to show this thing off…
Every board house should be able to handle traces down to 8 mils wide, and 20 mil (drill size) vias. Do you have a web site for your project, so that people can take a look at your design and perhaps offer advice?
yes, i will put the files where they can be available…
Ok, i have loaded some files on my website. if they are not sufficient, let me know. thanks in advance for all your help.
You might want to include the link…
here is the link…
It deinfinitely could be a lot smaller. Also, check your power trace widths; I see some heavy duty packages on there, but thin wires going to them.
We could do a lot more if you actually post design files…
right…trying to figure that out now…any ideas…
it’s good design practice not to have any 90-degree turns in your traces. Try to chamfer them all out to 2@45 degrees. This keeps the electrons from getting confused and also keeps solder from pooling up in the elbows.

I agree with the 45 deg angles. Looks better too.
I’d also flow grounded copper everywhere you can.
The sets of headers at the bottom look kind of close - what kind of connector hooks up there. I’d make sure there is enough room.
I agree on widening the power & gnd traces. You’ve got room, don’t scrimp.
ok, i have rerouted some of the wires and all seems well. i did get errors about soldermask… anybody know how to post brd files or sch files, so that others can take a look? All I can see how to do is add pictures…
