  • Bottompaste: The bottom layer needs to expose the part of the solder paste on the copper skin.
  • Topsolder: Should refer to the top solder mask to avoid accidental short circuits during the manufacturing process or future repairs.
  • Bottomsolder: Should refer to the bottom solder mask.
  • Drill guide: It may be a table of different aperture sizes, corresponding symbols, and numbers.
  • Drilldrawing: Refers to the whole bitmap, each different hole diameter will have a corresponding symbol.
  • Multilayer: There should be no single layer, which can refer to multi-layer boards, for single-sided and double-sided boards.
