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.

Stripboard is the generic name for a widely used type of electronics prototyping material for circuit boards characterized by a pre-formed 0.1 inches (2.54 mm) regular (rectangular) grid of holes, with wide parallel strips of copper cladding running in one direction all the way along one side of an insulating bonded paper board.
When potting a circuit board that uses surface-mount technology, low glass transition temperature (T g) potting compounds such as polyurethane or silicone may be used. High T g potting compounds may break solder bonds through solder fatigue by hardening at a higher temperature because the coating then shrinks as a rigid solid over a larger part ...
Closed-cell PVC foamboard is mainly used for industrial and manufacturing purposes. The material is primarily used in the manufacturing of signs and displays which are used for promotion ads, as well as road signs. [6] Its appealing material properties have made it popular among the makers of scale models and theatrical props. Builders who ...
Some blades cut through the material while others crush the material against a hard roll. Those are similar to knives. The cutting blades can be set to a desired width. Some machines have many blades and can produce a number of output rolls at once. The slit material is rewound on paper, plastic or metal cores on the exit side of the machine.
Facing on a milling machine is the process of cutting a flat surface perpendicular to the axes of the milling cutter. This process removes the material by rotating the facing tool in the counterclockwise direction as the table feeds the work piece across the cutter.
Scoring is used in place of cutting through the material all the way because you can obtain relatively the same results with less time and labor. However, when breaking along the score line the material may deviate from the set guideline, the back side of the break line often has a jagged edge to it from the shear fracture, and scoring offers ...
A cutting mat is a mat that is placed between a workpiece to be cut and the surface below (e.g. a table) to protect the surface. They are used, amongst other things, in hobby work for precise and clean cuts of paper, cardboard or textiles using a scalpel or rotary cutter .
