In our designs, we usually draw the Top overlay as the biggest size of the component - so you are sure if you place two components close to each other with touching Overlay, it will be possible to fit them. In assembly layer, we draw a simple shape around the component, but we do not use this layer as the component courtyard - it's just to show component location. -
Top Overlay vs. Courtyard
Is Top overlay layer (Yellow Line) same as courtyard space of the component? It seems they are different. How would we know how close the components can be to each other specially with SO8's or the ISIL chip. We don't show with the mask the necessary distance clearance to chip anywhere do we?
