The choice of material for your PCB is an important factor

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)

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.
