Micro Via’s, often used to describe any small geometry connecting holes, usually a finished hole diameter of 0.15mm (0.006″) or less.

Our Schmoll and Hitachi drilling machines are capable of drilling 0.15mm holes giving a finished hole diameter of 0.10mm (0.004″).

Due to the drill length and plating operation micro via holes are usually found on material thickness of 1.60mm or less.
