  • Laminates (substrates): rigid - flex

  • Number of layers:

    • Singlelayer



 

  • Doublelayers,through-holeplated,


  • Multilayer (2–20+layers)

  • Feature size: width of conductiv and insulating stripes

  • normal: 0,4–0,6mm >16mil

  • Fine: 0,3–0,4mm ~12–16mil

  • Veryfine:0,1–0,2mm ~4– 8mil

  (1raster=2,54mm, 1mil=0,01raster)
