I am trying to order a PCB from JLCPCB and have the following problem:

When I enter the BOM in the Assembly it does not detect U1, all the other components are detected. What could be the mistake?

    \$\begingroup\$ Ask JLCPCB? Rename it from U to something else? \$\endgroup\$

    \$\begingroup\$ You didn't specify an LCSC part number, it is not going to guess based on the comment field. \$\endgroup\$

    \$\begingroup\$ Maybe the fact that it is the last entry is causing it to get dropped, perhaps switch the order of the parts and see if that works. If it does maybe add a dummy entry. \$\endgroup\$

    \$\begingroup\$ It didn't pick up J1 and J2 either. Which are also missing the last field. That's probably a big clue. \$\endgroup\$

I solved it via changing the Reference like U1 to U2 and then updating all the Gerber files. Seems like the problem was a connection between the PCB Files and the BOM.
