摘要
A method and structure for an ink jet print head which includes the use of two or more flexible circuits and a piezoelectric element array. A first pad array is included on a first flex circuit to power a first portion of the piezoelectric element array of the print head, and a second pad array is included on a second flex circuit to power a second portion of the piezoelectric element array of the print head. Using two flex circuits requires only half as many traces to be formed on each flex circuit, which can relax spacing requirements and design tolerances.
