Abstract
An ink jet printer head fabricating method includes forming electrodes on surfaces of plural grooves by an electroless plating method using a wet process, the plural grooves being formed in a laminate substrate of two piezo electric members, cutting a portion of the laminate substrate with a dicing saw, and subsequently removing burrs of the electrodes by brushing with a brushing device. Burrs of the electrodes formed on the surfaces of the grooves are removed by the brushing without chipping or cracking of the electrodes, thereby preventing defects in ink ejection.
Claims9
A method for fabricating an ink jet printer head, comprising the steps of:
- forming electrodes on surfaces of plural grooves, the plural grooves being formed in a piezoelectric member of a substrate;
- disposing a top plate above the plural grooves and on support walls each formed between the adjacent grooves to define pressure chambers and a common ink chamber;
- cutting off an end face side of the substrate in which an end face is located on an open side of the grooves;
- brushing a resulting cut section of the substrate with a rotating brush to remove burrs of the electrodes;
- and
- attaching a plate to the cut section of the substrate, the plate being formed with a plurality of orifices for the ejection of ink which orifices correspond respectively to the grooves.
