Top-side PDF for LCFC motherboard NM-A181 at revision 1.0, a Lenovo board, labelled TOP in the name. Its size of 283 KB suggests a component placement drawing of the upper layer rather than the complete schematic, intended to be used with the matching BOT file. It helps technicians find reference designators, locate parts and test points and plan probing on the top side. LCFC, Lenovo's own ODM, numbers boards with the NM- prefix, so check NM-A181 and the revision on the PCB first.
