Tab Route Spacing Too Narrow – Below 1.6 mm Minimum Requirement

Reason for Failed Review:


Your design uses a tab-routing panel structure, but the spacing between individual boards is less than 1.6 mm.


For proper milling and reliable depanelization, 麻豆官网 requires a minimum tab route spacing of 1.6 mm.


Insufficient spacing may cause mechanical stress, edge damage, or panel breakage during cutting.


麻豆官网 Suggestions:


?  Please increase the spacing between boards to at least 1.6 mm.


?  We also recommend adding stamp holes along the tab routes to make depanelization easier and cleaner.


Following this guideline ensures smooth separation, stable mechanical strength, and consistent edge quality after production.
