Anodic bonding process and method of producing an ink-jet print head using the same process
TLDR
In this paper, an ink-jet print head is constructed by joining a head base to a vibrating plate without use of any adhesive and has a sufficient joining strength even if the joining layers are formed to be as thin as possible.Abstract:
A method of producing an ink-jet print head comprises the step of joining a head base to a vibrating plate without use of any adhesive and has a sufficient joining strength even if the joining layers are formed to be as thin as possible. The joining process comprises the steps of providing a head base of glass including an array of individual ink passages formed therein, forming an electrically conductive film on the joint surface of the head base through sputtering, superposing a vibrating plate of glass on the joint surface of the head base through the electrically conductive film, and applying a voltage between the head base and vibrating plate with the electrically conductive film and vibrating plate being respectively anode and cathode while being subjected to pressure and heat, thereby carry out anodic bonding the head base and vibrating plate to each other.read more
