Basis Material

We have a permanent stock of the standard basis material FR4. Furthermore, on request we can procure further variations of FR4 material, also in different thicknesses.

We process basis material in thicknesses from 0.50mm to 3.2mm, copper end thicknesses to 135µ with comparative tracking index (CTI) values to max 600 volts and a TG value of 150 degrees Celsius.
