The choice of material for your PCB is an important factor

controle-qualite-pcb (1)

When manufacturing your PCB prototypes, you must choose the PCB material. This choice is an important factor in the quality and service life of your PCBs, but also when obtaining approvals under European and American standards.

To guide you to the correct choice of material, below is our product line and the main specifications. If you require more detail, click on the material name to get the full documentation (datasheet)

FR4 Material (Rigid)

Standard FR4

FR4 High TG

FR4 High IRC

FR4 with no copper

  • This material is an epoxy glass with no copper designed for use in insulation plates, templates, board supports, etc. They are manufactured using gerber type mechanical drawings or DXF files.
    • Thickness from 0.3 to 5 mm.

Prepreg material (Rigid)

Standard Prepreg

Prepreg TG

    • Standard thickness 1.6 mm.

Prepreg High CTI

    • Standard thickness 1.6 mm.

SMI material (aluminium core)


Polyimide material (High TG Laminate)

Standard High TG Polyimide

ROGER material (material for high frequency circuits)


CEM3 material


  • ST215 CEM 3
    • Available thicknesses 1 mm, 1.2 mm and 1.6 mm.

Additional information

  • HAL finishes are only possible if your PCB is thicker than 0.4 mm.
  • Chemical finishes are compatible with all PCB thicknesses.
  • The choice between our VENTEC and ISOLA partners depends on their available stock.
  • TG (Glass Transition) is the temperature at which the material’s molecular structure changes.
  • CTI (Comparative Tracking Index) is a higher index that is used to limit the risk of electric arcs between tracks.
