Due to the wire width and the space between wires on PWB becoming finer the insulating capability of PWB is affected by ionicmigration, that was not paid enough attention to for a long time.
The relationship between the crystallographic structure and ionicmigration of lithium niobate single crystals are microscopically analyzed and investigated by their crystallographic characteristics.
