Technology Class

The technology class represents the complexity of the PCB and also affect the cost.

Unfortunately is it not possible to present the cost increase in figures step for step, as we rather prefer to have full access to the documentation to be able to do a reasonable assessment.

All values in µm (microns).


M6 is often regarded to be the standard class
Technology Classes  M5 M6 M7 M8  
Annular ring drill – outer layer pad >200 >165 >140 >125 A
