Abstract
A method of contouring crystal plates for frequency control. After plate dimensions are established, the plates are kept in a stack separated by a bonding material. The stack is immersed in an etchant which etches the exposed crystal edges in a manner which undercuts the bonding material, thus batch forming bevel contours on at least the outer portions of the major faces of each plate in the stack.
