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.

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
