Panelizing PCBs is a way to safeguard their integrity.
Panelization,also known as an array format, is used to process multiple boards while keeping them together in a single substrate. The process allows Pcb prototype manufacturer china tomaintain high quality while reducing costs.
The two most common methods of panelization are V-groove panelization and breakaway tab, or tab-route panelization.
Tab-Route PanelizationThis method permits placing PCBs of the same or different designs together. Space is left between the perforated tabs and the traces and surface mounted parts.This reduces surface stress and avoids splintering.
Depanelization is simply removing individual PCBs from the array. Several different methods are used to depanel PCB arrays:
Pizza Cutter– Used on V-grooves. Best for cutting very large panels into smaller ones, this method is inexpensive and low-maintenance.
Punching– A two-part fixture punches out single PCBs. Higher capacity, but higher maintenance and cost.
Depaneling Router– Single boards are connected using tabs; the router bit mills out the tabs. Can cut arcs and turn at sharp angles, but capacity is lower.
