Glue PZT to substrate by screen printing by Tam Nguyen (April 11, 2012)

l         Screen printing the silver-based conductive epoxy on the surface of the substrate.

²       Cut a retangular hole on the thin film with dimension of PZT

²       Put the horn at the desired position on the screen printing device

²       Spread a thin layer of the conductive epoxy on the horn¡¦s surface

l         Use tweezer put the back electrode of PZT plate onto the epoxy layer.

l         Adjust PZT to get the uniform thickness of conductive epoxy.

l         Use the hot air station, the temperature air at 120oC for the fastest curing time (10 minutes).

l        Then bond the fine electrical wires on the electrodes of the PZT using conductive epoxy.
