Layer structure

Multilayer 6 Lagen - 2,4 mm

Pressed board thickness *        2.39    +/- 10%
Overall thickness incl. galv. Cu and solder resist mask *        2.50    +/- 10%

Notes on layer structure:

  • * Thickness calculation with unfilled FR-4 base material at 50% copper allocation on the inner layers (depending on base material type, selected copper thickness and copper allocation, deviating resultant insulation and end thicknesses)
  • Thickness tolerance of base material +/-10%
  • Minimum copper end thicknesses in accordance with IPC 6012, current edition
