Build Question

[elosoman]

I just uploaded all the board info to pcbway and clicked the order button. Might you know anything about the following request?

Dear Customer, Thank you for your PCBA order [] , we checked all the files you uploaded and find there is no pick&place(centroid) file. Please go to 'Production Status' to upload this file . If you really can't provide this file, please contact your service representative to explain that.

I confess this is my first time going through the board production process. Might you have a clue on what this is or do i tell them i don't have one.

Thanks
