ABSTRACT:
A micro-fluid ejection head assembly having improved assembly characteristics and methods of manufacturing a micro-fluid ejection head assembly. The micro-fluid ejection head includes a fluid supply body having at least one fluid supply port in a recessed area therein. A reinforcing member circumscribes the fluid supply port. A micro-fluid ejection head is attached with an adhesive to the supply body in the recessed area so that cracking of the ejection head during adhesive curing is substantially reduced.
