Datum - Reference point (0,0) from which all other features on the substrate are measured.
Fiducial - A marking used as a standard reference for substrate orientation and alignment during metallization.
Machined Hole (Contoured/ Profiled/ Via) - A laser-cut feature produced by moving substrate in relation to a fixed beam position.
Machined Slot - cut or profiled feature produced by moving the substrate in relation to a fixed beam position, with length greater then width.
Pin Flat (Flat/ Pin Locations/ Alignment Flats) - Laser-machined reference plane, located on substrate edges used for precise mechanical alignment of the substrate in the customers process.
Popped Hole (Drilled/ Flashed/ Pulsed/ Via) - Pulsed or trepanned hole, laser-machined thru-hole processed by pulsing or rotationing the beam while the substrate is stationary.
Reference Notch (Chamber Corner) - Customer-specified feature used to define substrate or orientation during processing.
Scribe Line (Snap Line/ Pulse Line) - A controlled series of pulse at a specified depth and spacing, witch allows separation into circuit segments.
Tooling Hole (Reference/ Locating Hole) - Customer-specified optical and/or mechanical feature. Used to locate or fixture the substrate during metallization, assembly, or further processing. If using mechanical pin alignment, specify hole size using a go/no-go pin test.
