A minimum 3.8-mm (0.150") clearance should be maintained around the perimeter of the component.
If the edges of the boards are to be used for conveyer transfer, a cleared zone of at least 3.17 mm (0.125") should be allowed. Usually, the longest edges of the board are used for this purpose, and the actual width of the keep out area depends on equipment capability. Although no component lands or fiducials can be present in this area, breakaway tabs may be in it.
