A plurality of heater, formed by thin film layers (104, 112), are grouped together in six rows where two of the six rows are arranged adjacent to the first longitudinal side of one of the two outer vias, two rows are arranged adjacent to either the first or second longitudinal side of the inner via, and two rows are arranged adjacent to the second longitudinal side of the other of the two outer vias. Each of the first, second, and third rows have one row of near heaters (B, D, E) and one row of far heaters (A, C, F).
