PCB layer sequence? #25

Closed JonnyHaystack closed 8 months ago

JonnyHaystack commented 3 years ago

Hi, I'm not sure how to put in the layer stackup/sequence to get the main PCB manufactured from JLCPCB.

Could you advise on this, and maybe put something in the wiki Appendix A about it?

Thanks

Hey! Have you find the solution?

The files we have are:

Base.apr
Base.EXTREP
Base.G1
Base.G2
Base.GBL
Base.GBO
Base.GBS
Base.GD1
Base.GM2
Base.GTL
Bse.GTO
Base.GTP
Base.GTS
Base-macro.APR_LIB

Looking at this site it says:

APR: Aperture file
GTL: Board top layer
GTB: Board bottom layer
G1, G2, etc.: Inner layers
GP1, GP2, etc.: Power and ground plane layers

So JLCPCB's layer names:

L1 (Top Layer) -> Base.GTL
L2 (Inner layer 1) -> Base.G1
L3 (Inner layer 3) -> Base.G2
L4 (Bottom layer) -> Base.GTB

I'm not familiar with Gerber files so not sure what the rest are.

In general G=Gerber, B=Bottom, T=Top

GTO/GBO - O= "Overlay" aka silkscreen GTS/GBS = S=Soldermask, a negative image to define exposed copper GTP - P=Paste, solder paste stencil layer for automated assembly. No bottom paste was included because there's no bottom surface-mounted components GM2 = M = Mechanical CAD layers, in this case the board outline and cutouts

I recommend downloaded Pentalogix ViewMate gerber viewer, always good to review your Gerber outputs and it helps make the filetypes a bit more intuitive.

Closing; we can't advise on your relationship with your board house.
