Question for Discussion group:


Could anyone give me a schematic crossection of a bubble jet printer
head ?
I need the materials data (substrate-, thermal insulator-, passivation
layer-, heater material)
and the sheet thicknesses !

I only have very old datas. I am interested in the structure of a state
of the art ink jet
printer head (for example a hewlett packard printer head)

Any data and information are helpful for me. If you have pictures you
can sent it per
attachment.

Thank anyone very much in advance for the help.
