Abstract

The present teachings describe a printhead assembly. The printhead assembly includes a first plate and a second plate stacked together. The printhead assembly includes a first adhesive between the first plate and the second plate for bonding the plates together. The printhead assembly includes a second adhesive surrounding an outer edge of the first adhesive wherein the second adhesive has an oxygen migration rate lower than an oxygen migration rate of the first adhesive. An oxygen sensitive component is contained within the outer edge of the first adhesive.

Claims11

Dependent claims

A printhead assembly comprising:

an oxygen-sensitive component;
a first plate and a second plate;
an effective amount of a first adhesive component on respective surface portions of each of the first and second plates for adhesively bonding the first and second plates together;
and
an effective amount of a second adhesive component on respective surface portions of each of the first and second plates, spaced an offset distance from the first adhesive component for enabling the oxygen-sensitive component to be contained by the first adhesive component,
wherein the second adhesive component possesses an oxygen-migration rate that is less than an oxygen-migration rate for the first adhesive component.
