Abstract:
An inkjet nozzle assembly has a chamber with a nozzle opening for ejecting a liquid, a heater element disposed in the chamber, and a dielectric layer sandwiched between the heater element and a wall of the chamber. The dielectric layer has a thermal product of less than 1495 Jm−2K−1s−1/2. The thermal product is defined as (ρCk)1/2, where ρ is the density of the layer, C is specific heat of the layer and k is thermal conductivity of the layer.
