To overcome these challenges, engineers may use SMT fixtures or the panelization techniques. Each of the two methods provides a carrier with standard dimensions and provisions for fitting, securing and supporting the irregular boards.
Depanelization is the process of separating the individual boards from the main array and usually depends on the panelization method applied. The choice depends on the clearance to provide at the edges of the PCB, and the presence of sensitive SMT devices, or hanging connectors near the edges. There are automatic methods, such as the laser cutting or depaneling router, as well as manual methods that involve breaking the tabs using hands or other tools.
