ABSTRACT:
In accordance with the invention, there are jet stacks, ink jet print heads, and methods of making jet stacks and ink jet print heads. The method of making an ink jet print head can include providing a partial jet stack including a diaphragm, a plurality of port holes, and having an ink outlet side and providing a polymer planarized piezoelectric array. The method can also include bonding the polymer planarized piezoelectric array to a side opposite to the ink outlet side of the partial jet stack using an adhesive, wherein the partial jet stack is aligned such that the planarized polymer covers the plurality of port holes, and using the partial jet stack as a mask to extend the port holes through the polymer by ablating the polymer and an excess portion of the adhesive from the ink outlet side using a laser.
