Victor,

J-STD-001 Rev E Para. 6.1.4 states that leads trimmed shall have the solder reflowed or inspected at 10X for damage.
And if the trim cuts into the solder fillet, it must be reflowed.

Fellow TechNetters:

Does IPC Standards address the lead trimming of components on post solder assemblies. I heard that on post solder lead trimming that a second pass solder operation is required to ensure solder joint integrity from the lead trimming process. Any comments and/or direction for literature review.

Victor,
