Altium PCB Update & JLC

I have three existing Altium Designer projects that must be refreshed before the next manufacturing run at JLCPCB. Both the schematic and the board layout need attention. On the schematic side I already know the exact edits: a handful of parts have to be added or removed, several nets must be reassigned, and a few voltage- and current-related values updated. Once those changes are in place the PCB layouts have to be brought in line—rerouting where required, keeping the original board outlines and mechanical constraints intact, and making sure every DRC/ERC check comes up clean.

When the files are solid I need a full, ready-for-upload manufacturing package:

• Updated Altium project files (.PrjPcb, .SchDoc, .PcbDoc)
• Gerber and NC-Drill set generated with JLCPCB’s default stack-up
• BOM & PNP in JLC template with correct LCSC part numbers and sourcing options
• Pick-and-place (CPL) file with reference designators, X/Y, rotation, and layer info
• Assembly drawing or PDF so nothing is left to interpretation

I’ll provide the current design folders, libraries, and a brief change log as soon as we start. The job is finished when the updated data passes JLCPCB’s online pre-check without errors.
