Ink Jet Nozzle Mounting

An ink jet nozzle plate 10 is a thin membrane having thin slices of glass tubes 11 imbedded therein. The glass tubes each include a hole 12 which forms an ink jet nozzle.

To provide structural support, the nozzle plate is mounted on a substrate 13 having a plurality of holes 14 which are smaller than the glass tubes 11 and larger than the nozzles 12. To bond the nozzle plate to the substrate, several small quantities 15 of a liquid bonding material, e.g., epoxy, are placed along the edge of the nozzle plate so that capillary forces draw the liquid into the interface between the nozzle plate and substrate. Since the capillary forces are strongest in the smaller gap, the liquid will not enter the holes 14 in the substrate but will flow around the holes to form a bond.
