Need help with PCB manufacture in JLCPCB #4

Closed TQBCPC closed 1 year ago

TQBCPC commented 1 year ago

Hi,

I am trying to have the PCB made in JLCPCB, but in the component placement, I get components wrongly placed. What am I doing wrong? Could it be the CPL file?

Thank You for this great project, Tiago

Hi @TQBCPC Yes the CPL only provide correct placement (orientation) for some smaller surface mount components. Chips and bigger caps/inductors need to be adjusted accordingly.

Do you have any idea how to fix this issue?

TQBCPC commented 1 year ago

With a lot of trial and error I think I was able to place them. capture-2023-07-09T00_58_12 681Z CPL-pico_expansion_board_teste.csv capture-2023-07-09T00_58_00 699Z

But I'm unsure about the L1 Power inductor orientation and the U3 orientation.

eamars commented 1 year ago

The power inductor is unipolar. I will check the orientation of U3 tonight But thank you very much for your help on that! I will seek to merge your change today.

eamars commented 1 year ago

Your placement is correct. I've merged your change. Thanks again for your help!
