Abstract:
A method for assembling an inkjet printhead, comprising:providing a thinfilm die with a barrier layer comprising a thermoplastic component and a thermoset component; prior to bringing an orifice plate in contact with the barrier layer, heating the barrier layer in a first heating step such that the barrier layer becomes tacky but not liquid; aligning an orifice plate to the tacky barrier layer; prior to staking and baking an assembly of the thinfilm die, the barrier layer and the orifice plate, bringing the orifice plate in contact with the tacky barrier layer, whereby the orifice plate is held in place on the barrier layer by the tackiness of the barrier layer thereby bonding together the thinfilm die, the barrier layer and the orifice plate; and staking and baking the assembly of the thinfilm die, the barrier layer and the orifice plate in a second heating step, whereby the orifice plate becomes permanently attached to the barrier layer by a baking and curing of said thermoset component.
