Location Hole


Location holes are non-plated-through holes (Npth), which allow an accurate positioning of the printed circuit board for processing. The placement of the location holes is based on the requirements of the machine used, usually asymmetrically in order to avoid a rotated position. The custom-fit catching of the holding pins allows a very low tolerance for further processing.

In printed circuit board production, location holes help with stack processing, e.g. drilling
or milling of a whole stack of printed circuit boards.
