Laser вЂ“ Low mechanical stress and precise tolerances, but has higher initial capital outlay.Saw вЂ“ Can perform at high feed rates, cutting both V-grooved and non-V-grooved PCBs.Can cut arcs and turn at sharp angles, but capacity is lower.

Depaneling Router вЂ“ Single boards are connected using tabs the router bit mills out the tabs.Higher capacity, but higher maintenance and cost. Punching вЂ“ A two-part fixture punches out single PCBs.Best for cutting very large panels into smaller ones, this method is inexpensive and low-maintenance. Breaking by Hand вЂ“ Only appropriate for strain-resistant circuits.Several different methods are used to depanel PCB arrays: 2) DepanelizationДepanelization is simply removing individual PCBs from the array. This reduces surface stress and avoids splintering. Space is left between the perforated tabs and the traces and surface mounted parts. Tab-Route Panelization This method permits placing PCBs of the same or different designs together. V-Groove panelization is used where there are no overhanging components. The remaining board is quite sturdy and is depaneled by machine to avoid stress on the PCB. V-Groove Panelization вЂ“ This method involves cutting 1/3 the thickness of the board from both the top and bottom with a 30- to 45-degree circular cutting blade. The two most common methods of panelization are V-groove panelization and breakaway tab, or tab-route panelization. The process allows PCB manufacturers to maintain high quality while reducing costs. Panelization, also known as an array format, is used to process multiple boards while keeping them together in a single substrate. Panelization must be done properly so that PCBs will not be broken or otherwise damaged during separation.ДЇollowing is a discussion of PCB panelization methods, as well as some challenges that may be encountered. In addition, panelization allows PCB manufacturers to assemble multiple boards simultaneously, reducing costs and production time. Panelizing PCBs is a way to safeguard their integrity. Printed circuit boards (PCBs) need to be kept secure during the manufacturing, shipping, and assembly processes to avoid damaging the unit.
