AI Technical Summary
Technical Problem
In the liquid ejector head, the electrode section malfunctions due to liquid corrosion and the latch-up effect of the driver IC, affecting the normal operation of the ejector head.
Method used
Electrodes are provided on both sides of the substrate, and the second liquid hole is covered by a shielding component to prevent the liquid from contacting the electrode. A multilayer electrode film structure is used to reduce the resistance value, and a water-cooling circulation structure is combined for temperature control.
Benefits of technology
It effectively prevents electrode corrosion, reduces latch-up effect of driver IC, and improves the reliability and stability of liquid nozzles.
