Hello GŁnni,
I see that while unzipping the zipped gerbers, there are 2 folders. Folder 1 containing the gerbers and folder 2 containing the drill file. This may probably be the reason why jlcpcb site is not showing properly.

Just a guess. otherwise everything is properly formatted as xrk already got them manufactured.
If gerbers are ok with gerberlogix, they will be ok for manufacturing, my experience.

regards
Prasi

Amazing looking pcb, congrats Prasi.

Quick question; there are 6 output terminals (4 x Gnd, 1xV+, 1xV-)
Looks this this pcb is intended for mono amp.

I believe it would be better to have (2x Gnd, 2xV+, 2xV-) this way people can use a single cap mult to power a stereo amp.

My 2 cents
Eric

Hello Eric,
Yes, you are correct. I missed out.
However there is following solution.

If one requires 2 numbers of V+ wires, a two pin terminal block can be made to fit for the V+ terminal if your C4 is 10mm dia. otherwise horizontal termi block would fit easily.

Also, beware that when using a single cap mx to power two amp PCBs, you run the risk of pesky ground loops.

I manually placed the drill file in the same directory before re-zipping it. Then used that to upload to JLCPCB. $2 for 10 is quite the deal if an "add-on" to another order that you already have and that takes care of shipping. Under 100mm square board Gerbers are great to have on hand as add-on orders.

What I’ve seen creating the most ground loops is when using 1 power transformer feeding 2 Cap M.
1 transformer feeding 1 cap M (stereo) is usually ok OR
2 transformers feeding 2 cap M (double mono) is also OK

Hello X,


is it possible to upload your Gerbers, you have sent to JLCPCB? If i do the same, as you did, i get an error on JLCPCB, says missing board outline. In the zip file it is present.

Not sure why you are having so many problems. I just went to post #512, downloaded the file there, and submitted to JLCPCB - and it accepted it no problem. The Gerber viewer shows the board correctly. I also uploaded it to Online Gerber Viewer and checked there and it works too.

So here is the link to the tested Gerber file: https://www.diyaudio.com/forums/atta...2018-08-31-zip

You might try renaming the extension of the drill file from .txt to .drd and place in same directory - this is done in the attached file below and it works well in Gerber viewer.

Hi X,


Thanks, but i have no problem with that. Attached you see, what the Gerber viewer from JLCPCB made out of your uploaded file.
See also the analysis results (2) and the automatic detection of size not works (3).
All other layers are ok.
