Upload the "gerber.zip" file by clicking the "Add Gerber File" button.
The default setting are correct, blue color PCB's are recommended, but it will add two days to the build time.
NOTE: Surface Mount Assembly Service is only required for designs ending in "SMD" or "SMT", all other designs can skip this step.
Scroll down and Enable the SMD service.
Select "Assemble top side" and "Added by JLCPCB" for tooling holes.
Then click "Next" on the right by the Calculated Price heading.
On the Next page, you will select the BOM and Part Position Files.
'xxxxx_SMD.csv' is the SMD BOM and 'xxxxx-all-pos.csv' is the SMD CPL position file.
The next page will confirm all the BOM parts in the SMD CSV file. Select "Next" to proceed to placement review. If they are incorrect, let me know and I will update the LCSC part numbers.
The final page will confirm all the part placements in the POS CSV file. The "dots" should match the pin 1 locations on the IC's. If they are incorrect, let me know and I will update the rotation values.
Then Save to Cart and proceed to Checkout and Shipping like normal.
