Abstract
A stimulator for a continuous ink jet print head is fabricated by providing a surface roughness of between 100 and 200 microinches on the surface of the stimulator body and attaching a piezoelectric transducer strip to the body using an acrylic cement having a viscosity of between 2 and 100 centipois. The resulting stimulator exhibits improved lifetime with acceptable acoustic properties.
