Claim 19:
20. A method for forming a heat exchanger plate, the method comprising:
providing a precursor having:
a body with a first face and a second face opposite the first face and at least one internal passageway;
a plurality of first fin precursors protruding from the first face; and
a plurality of second fin precursors protruding from the second face; and

forming a first fin height profile of a first plurality of fins by removing material from the first fin precursors via wire electro-discharge machining to cut tip sections from the first fin precursors; and
forming a second fin height profile of a second plurality of fins by removing material from the second fin precursors via wire electro-discharge machining to cut tip sections from the second fin precursors.
