Eurocircuits Insight Technology – Tolerance on Drill Hole Diameter from Eurocircuits on Vimeo.

As a PCB Designer you expect a hole that you define as 0.85 mm to be 0.85 mm on the produced PCB. Unfortunately no manufacturer can offer you that. In this video we explain the production reality that causes tolerances on hole diameters.

Consult our tolerance table eurocircuits.com/tolerances-on-a-pcb/ or visit the Eurocircuits.tv website for more videos on hole diameter tolerances, track and isolation tolerances and tolerances on material thickness.
