A milled printed circuit board. Printed circuit board milling (also: isolation milling) is the milling process used for removing areas of copper from a sheet of printed circuit board (PCB) material to recreate the pads, signal traces and structures according to patterns from a digital circuit board plan known as a layout file.

On-board LPC-LINK for programming and debugging via a MiniUSB connector. Board can be cut into two separate boards: LPC-LINK board and target microcontroller board. Power input from 5 V via the USB cable or 5 V external power. If boards are separated, then 3.3 V external power is required for the target microcontroller board.
Four-PCB panel. Depaneling or depanelization is a process step in high-volume electronics assembly production. In order to increase the throughput of printed circuit board (PCB) manufacturing and surface mount (SMT) lines, PCBs are often arranged in a process called panelization so that they consist of many smaller individual PCBs that will be used in the final product.
The cut made in lancing is not a closed cut, like in perforation even though a similar machine is used, but a side is left connected to be bent sharply or in more of a rounded manner. [citation needed] Lancing can be used to make partial contours and free up material for other operations further down the production line.
Such back-cutting operations can obviate second operations, [2] with their attendant setup time and part rehandling time. Sometimes the limiting factor in applying this advantage is the difficulty of chip clearance; the operator needs to intervene because chip nests prevent the tool from passing freely and opening and closing freely.

CNC plasma cutting Plasma cutting performed by an industrial robot Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma . Typical materials cut with a plasma torch include steel , stainless steel , aluminum , brass and copper , although other conductive metals may be cut as ...
Foamcore, foam board, or paper-faced foam board is a lightweight and easily cut material used for mounting of photographic prints, as backing for picture framing, for making scale models, and in painting. It consists of a board of polystyrene foam clad with an outer facing of paper on either side, typically white clay-coated paper or brown ...
Quarter sawing or quartersawing is a woodworking process that produces quarter-sawn or quarter-cut boards in the rip cutting of logs into lumber. The resulting lumber can also be called radially-sawn or simply quartered .
