Raised fluid pass-through structure in print heads

A print head includes a substrate having a hole, a circuit on the substrate, the circuit having traces and a hole corresponding to the hole in the substrate, the hole forming a fluid path, and a raised structure on the substrate around the fluid path, the raised structure positioned to seal the circ...

Beschreibung
Zusammenfassung:	A print head includes a substrate having a hole, a circuit on the substrate, the circuit having traces and a hole corresponding to the hole in the substrate, the hole forming a fluid path, and a raised structure on the substrate around the fluid path, the raised structure positioned to seal the circuit from the fluid path. 本发明提供种打印头，其包括：具有孔的衬底；在所述衬底上的电路，所述电路具有迹线和对应于所述衬底中的所述孔的孔，所述孔形成流体路径；以及在所述衬底上围绕所述流体路径的凸起结构，所述凸起结构定位成将所述电路与所述流体路径封隔。
