what program did you use for the design?
im interested in this, as far as the reading and writing times goes for xbox nand. if all goes well, let me know 3d0. i'll order a few and test them out.
the holes you see are where the pin header would go
The holes looks like vias and may not be easy to solder to due to silkscreen possibly covering them. They also look to be on the small size and does not seem to be spaced evenly for a pin header.Schematics looks good.Edit: Actually, the resistors pads look like they are touching?
Ya everything looks good but instead of the holes for the pin header, i would just do open copper pads to solder to. Also, could you include a parts list. I think theres a crystal and not sure what resistors are supposed to be and also the microcontroller. Im assuming a pic18f2550?
Depending on the fab house and size of the via, silkscreen do sometimes cover the vias.I have never use diptrace before and have no idea how that program works, usually for spacing you would make them in the component editor section of the program (which was a huge pita when I first used it). However pin headers are very common and all pcb programs with libraries should already have footprints for them.
Are you gonna add the pads for leds? If so, are you still sticking to 0805 or are you gonna use 0603 add that its more common?
This is just a quick look over it, I haven't dug into the gerbers and compared to the original yet, and it's meant to be constructive criticism also, not a tear down of the work.For that size board, you have everything really crammed together. Short traces aren't always best, and for something like this it's not going to matter.* so should i make the board bigger or is this for future ref saying short traces arent always good?Don't come out of a pad at an angle, unless it can't be avoided. The traces at pins 8, 9, 16, 24 and 26 should be redone.*hmm didnt know it made a diff will redoYou have C1, C2, C3 and C4 different in your parts list versus the original one.*lol yeah i didnt wanna go back and redo it but as long as they follow the info in the text should be good no?You should not have Vias in pads where components will mount. For empty pads it's a 50/50 deal, but where a component goes is a no-no. The Vias on pads 17 and 23 on the PIC and 1 each on C1 and C2 should be moved so they are outside of the pads.*will redoThe USB footprint you're using locks someone into using that connector, which there's no part # for. *the lib for usb is pretty horrible imo what usb connector do you suggest?There are no pads for programming the PIC. Being it's SMT, it would just make things easier if they where there so no one has to solder to the PIC to program it, or a header for them in the correct pinout so the PK2/3 could just be plugged into it or a cable soldered up for programming.*any ideas for this suggestion?The headers you're using have a 1.27mm spacing, they would be better spaced at 2mm or even 2.54mm headers or pads.* will redo
Lol guess I'll make do with what i got. Might i suggest using 0603 to give your self a little more room?
