I really like the quality of the stores "blue" circuit boards, eg. The Universal Power Supply board. Can someone tell me who the manufacturer is and what thickness the copper is? Those boards withstand repeated soldering/desoldering really well. Thanks in advance.
Here is the link.
Since it says 70um copper, I am assuming 2 oz of copper which is plenty for Class A circuits. I bet they are 2mm thick boards too to accommodate the heaviness of the capacitors and rectifiers.
I don’t know who the manufacturer is, but many of us use JLPCB.
I do not believe the Gerbers are freely available.
You should ask on the DIYAudio Universal Power Supply thread.
Best,
Anand.

Thanks for the info, i should have read their description.I'm not trying to copy their boards,just looking for board specs so i can have some made.
The boards are actually 2oz copper thickness and the board is 1.6mm thick. Going to 2mm thick increases the cost quite a bit in small numbers.
I have had no problems at all with using JLCPCB for this spec - and they are cheaper than most other fabs.
