摘要： An ink jet head circuit board is provided which has heaters to generate thermal energy for ink ejection. This board has the heaters formed with high precision to reduce their areas. It has provisions to protect the electrode wires against corrosion and prevent a progress of corrosion. The substrate is deposited with the thin first electrodes made of a corrosion resistant metal. Over the first electrodes the second electrodes made of aluminum are formed. The second electrodes are deposited with a resistor layer. The heater is formed in the gap between the first electrodes. With this construction, the heaters are formed without large dimensional variations among them. Should a defect occur in a protective layer above or near the heaters, a progress of corrosion can effectively be prevented because the material of the resistor layer is more resistant to encroachment than aluminum and the first electrodes are corrosion resistant.

摘要： An ink jet head circuit board is provided which has heaters to generate thermal energy for ink ejection as they are energized. This circuit board reduces areas of the heaters to achieve higher printing resolution and image quality. This board also prevents a degradation of thermal energy efficiency and reduces power consumption. The protective insulation layer for the electrode wire layer is formed of two layers and one of the two layers is removed from above the heater to improve the heat energy efficiency. The resistor layer is deposited over the electrode wire layer. The patterning for removing the protective insulation layer is done in a wider range than a gap of the electrode wire layer, the gap being used to form the heater. Further, by forming the electrode wires in two layers, a possible reduction in an effective bubble generation area of the heater can be prevented.
