V-Cut
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 technology, surface mount (SMT) lines, PCBs are often arranged in a process called PCB panelization, panelization so that they consist of many smaller individual PCBs that will be used in the final product. This PCB cluster is called a panel or multiblock. The large panel is broken up or "depaneled" as a certain step in the process - depending on the product, it may happen right after surface-mount technology, SMT process, after in-circuit test (ICT), after soldering of through-hole elements, or even right before the final assembly of the PCB assembly (PCBA) into the enclosure. Risks When selecting a depaneling technique, it is important to be mindful of the risks, including: * Mechanical strain: depaneling can be a violent operation and may bend the PCB causing some components to fracture, ...

Pizza Cutter
A pizza cutter (also known as a roller blade) is a handheld kitchen utensil that is used to cut various items into sections or slices. Due to its prevalence in the making of pizza, it has earned the name "pizza cutter". The typical pizza cutter has a wheel-shaped blade that is attached to a handle. The original design has been modified over the years to include different sizes, blades, handles, and uses. The typical pizza cutter is not limited to cutting pizza but also for a variety of other tasks such as cutting dough or chopping herbs. History The Italian Silvio Pacitti invented the ''mezzaluna'' (Italian for "half moon") shaped blade in 1708. This utensil was a rounded blade that impacted its target and finished with a rolling motion across the object to create a clean cut (as opposed to dragging across the target, as with standard knives). It was intended to assist in cutting herbs and vegetables and could be found in either a single or double blade. Varieties There are two ...
