Is below the correct interpretation of IPC 610/JSTD requirements for FLAT LUG LEADS (seen on USBs and Diodes mainly) For class 1 or 2, no toe wetting would be required as minimum side joint is only 'evident wetting' and no actual length or fillet he

Fillet Height [F]. Wetting is evident on the vertical surface of the termination as the minimum fillet height.
