easy, just dip the ICs on a very weak solution of Nitric Acid, by very weak I mean like drops of Fuming Nitric acid in a half full DI water beaker. Place the beaker on a Ultrasonic bath and dip/shake the ICs in the solution in 5~ 10 seconds only. You

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.

If the solder joint meeting 8.2.5.4, minimum side joint length(D) and also meeting 8.2.5.6, minimum heel fillet height (F) but the heel fillet NOT extend to the mid point of outside bend. It is acceptable?

We'd say yes, if it meets both 8.2.5.4 and 8.2.5.6
