Toe down solution: * Land pattern design * Solder stencil design * Proper component fabrication Normal gull wing lead solder requirement: Solder must extend to the mid-point of the outside of the lead bend.

IPC also states that side overhang on a gull wing of 50% is acceptable for Class 2. Does anyone know if that interprets to only one side having a fillet? Also with toe overhang acceptable, there need not be a toe fillet.

The only way we can consistently get a toe fillet is to use a paste with an extremely active flux. We allow that paste on certain products, but discourage it's use because it's on the hairy edge of not meeting our lower limit in surface insulation r

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

We see no advantage to extending the toe-end of pads. Hell, 90 percent of the time the numb-end of the toe of the component lead isn't plated. So, it doesn't take solder. Further, solder on the toe adds little, if anything to the strength on the sold

Is toe fillet still required?

I agree 100% The strength of the joint is contained at the interface. Ever seen a fillet on a mail stamp?

Long, yellow, ugly toe nails will have the same affect on your boards.
