Answer
The metal contained in the electronic material that is ionized by the influence of the electric field moves between interelectrode. Afterward it is extracted to the metal again by deoxidization. It is called Dendrite among the ion migration phenomena because we can see tree branch like migration under microscope observation.
We can see Dendrite growth at both anode and cathode electrodes. It depends on degree of ionized metal movement. It may change in the same test specimen under different conditions or factors.
Some of the countermeasure are as follows : improving moisture resistivity of material and reducing impure residue at PCB processing.
