FLATTENING METHOD FOR INTERSTITIAL POLYMER USING FLEXIBLE FLAT PLATE

摘要

PROBLEM TO BE SOLVED: To provide a method and a structure for forming an interstitial layer of an inkjet print head which has a dielectric interstitial layer to a uniform thickness.

SOLUTION: A flexible upper plate 72 stuck to a press can be used to apply pressure to an uncured dielectric interstitial layer 50. The uncured dielectric interstitial layer 50 is brought into contact with the flexible upper plate 72 and is cured while holding the contact and while applying a pressure to the uncured dielectric interstitial layer 50 using the press 68. Use of not a hard upper plate, but the flexible upper plate 72 forms an interstitial layer which is more uniform or has a flat upper surface on the array of piezoelectric elements 20.
