Why add PCB break-up tabWhen PCB makers make PCB files, we often need to add break-up tab on the unit board or panel. This paper describes the design specifications of common break-up tab.In the process of PCB design, for some reasons, the distance between the edge of components and the long edge of PCB is less than 5 mm. In order to ensure the efficiency and quality of PCB assembly, the designer should add the break-up tab to the corresponding long edge of PCB.2019-07-17

Why special treatment of PCB surface?Because copper is easy to oxidize in air, the oxide layer of copper has a great influence on soldering. It is easy to form false welding and false welding. In serious cases, it will cause the pad and components cannot be welded. Therefore, PCB will have a process in manufacturing, coating (plating) on the pad surface to protect the pad from being oxidized.2019-07-16
