Laminated support structure for silicon printhead 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 ( 1 ) 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.
