Title:
MANUFACTURE OF INK JET RECORDING HEAD
Document Type and Number:
Japanese Patent JPH04369546
Kind Code:
A
Abstract:
PURPOSE: To enhance the characteristics of a head by setting the viscosity resistance and inertial resistance of an ink passage to the optimum values by forming a flow passage substrate from two or more photosensitive resin layers.
CONSTITUTION: A first layer photosensitive resin 2a is laminated to a glass substrate 1 to be exposed through a first mask pattern and a second layer photosensitive resin 2b is further laminated to said first layer resin to be exposed through a second mask pattern and the unexposed parts of the photosensitive resins 2a, 2b are developed to form the flow passage substrate of an ink jet recording head having nozzles 5a, pressure chambers 5b, flow passages 5c, an ink reservoir 5d respectively different in depth.
