Laminated support structure for silicon printed modules

摘要

A printhead assembly for an ink jet printer that has an elongate support structure (1) that attaches to the printer and is adapted to accept a printhead (2) that mounts to the support member (1). The support member is formed from a number of laminated materials (3, 4) having different coefficients of thermal expansion. The support member materials (3, 4) are selected and structurally configured so that the effective coefficient of thermal expansion of the support member as a whole substantially matches that of the silicon nozzle substrate material.
