Short Grown on Printed Circuit Board
Reflected Darkfield Illumination
In the presence of polar organic contaminants tin from solder will grow across the circuit board between to sites of opposite potential. Over time this will result in the failure of the circuit board. In this photograph there is a post in the lower right and an active circuit along the upper area of the field.
