HPS 6.1

[rsavas]

Interesting, Acrylic, Metallized, good find
Thx for the tip

(but the check passed!) with what design rule? 2.5mil pad/trace

JLC DRC
JLCPCB

Pad to Track 0.2mm (~0.0078mil)
5/5 mil width/spacing for 1oz outer layer

makes you wonder why/how they did not catch it, or they do not care if you have a violation, or they can process that without an issue.
The flying probe test just checks trace end point continuity.

Hello,

I have just built the HPS 6.2.

Now I have some HF-issues which leads to high noise. I used 1uH ferrites as shown in the schematic. In the picture you are using 2.2uH. I'm wondering from which manufacturer they are. Any recommendations on correct 2.2uH ferrites?

Is it also possible to adjust C204 and the Zobel network?

Thanks in advance.

Regards
Frank
