    This appears to a visual anomaly that should not impact solderability. The defining specification is MIL-STD-883 Method 2009 for external visual inspection. The definition of a reject is “Scratches that expose base metal over more than 5% of the lead surface area. Exposed base metal on the cut lead ends is acceptable and does not count in the 5%.” For this package the base metal is non-plated Alloy-42.
