so you did some manual reworking in the past? what about my suggested reworking by soldering iron is it good enough.

I don't think I will ever make +1000 at once, at least not in foreseeable future. actually, for 100 it is kinda ok financially, just not good enough for making good profit margin. I assume 1000 or more is going to be really negligible loss of money if we choose copper filling.

ataradov:
What you will have to do depends on the nature of the issues you will get. There is a high chance that you won't get any issues.

Don't overthink it. You have the hardware on a way, just wait and see.

Hello all, as I mentioned here: https://www.eevblog.com/forum/projects/my-psu-design-ripple-and-noise-with-picture-measurements/msg4518794/#msg4518794

the project works as intended and there were no problems in spillage and so on, actually the holes are extremely small and I think it is kinda impossible for solder to spill from there... very narrow.

the 3.3v rail has nice clean 5-10mv p-p total noise\ripple... but the 5v rail is significantly bad at about 40mv p-p which is shocking to me!

I am trying to know the root problem as seen in my last post there, which I suspect it is due to long travel of the 5v signal then routed by a via under 3.3v ferrite bead.

for your help if you can.

I was VERY close to finally wrap this and start production... so hyped
