摘要： A polyimide photoresist for thick film flow features adheres to a polyimide nozzle plate or other materials, without the use of an adhesive material between the two surfaces. Further, the photoresist can utilize an acrylate UV initiator, which can reduce the potential for HF to interact with the ink, and which can cause flocculation and eliminate the need for extremely long postbake cures used to remove HF from the photoresist. In another embodiment, an epoxy adhesive containing a dicyandiamide catalyst can be used to improve adhesion between polyimide films and a respective substrate.
摘要翻译：用于厚膜流动特征的聚酰亚胺光致抗蚀剂粘附到聚酰亚胺喷嘴板或其它材料上，而不在两个表面之间使用粘合剂材料。此外，光致抗蚀剂可以利用丙烯酸酯UV引发剂，其可以降低HF与墨水相互作用的可能性，并且其可引起絮凝，并且不需要用于从光致抗蚀剂中除去HF的极长的后烘烤固化物。在另一个实施方案中，可以使用含有双氰胺催化剂的环氧粘合剂来改善聚酰亚胺膜和相应基材之间的粘附性。

摘要： A method is provided for making a multi-fluid cartridge for holding multiple fluids in segregated containment localities. The cartridge body contains fluid supply paths in fluid flow communication with the containment localities. A nozzle plate is attached to a device side of each of a plurality of defined ejection head substrates on a semiconductor wafer. Each of the ejection head substrates has a fluid supply side and two or more fluid flow paths therein for supplying fluid from the supply side to the device side thereof. The fluid flow paths in the ejection head substrates have a flow path density of greater than about 1.0 flow paths per millimeter. The wafer is diced to provide a plurality of micro-fluid ejection device structures. A circuit device is attached to the device side of each of the substrates. An adhesive is stencil printed with a bond line density of at least about 1.2mm -1 on the micro-fluid ejection device structures or on the cartridge body. At least one of the micro-fluid ejection device structures and attached circuit is adhesively bonded to the cartridge body for flow of fluid from the containment localities to the device side thereof.

摘要： A flexible circuit having improved corrosion resistance and method therefor. The flexible circuit includes, a polymeric support substrate, a conductive layer providing tracing attached to a first surface of the support substrate, and lead beams in electrical communication with the tracing for attaching the flexible circuit to a micro-fluid ejection head. A plasma polymerized layer is deposited on at least a portion of the conductive layer to reduce corrosion of the conductive layer. The plasma polymerized layer may also improve adhesion between the flexible circuit and an adhesive use to attach the flexible circuit to a structure.

摘要： A device surface of a substrate is dry-sprayed with a polymeric material (e.g., a photoresist) to provide a spray-coated layer on the surface of the substrate. The spray-coated layer has a thickness ranging from about 0.5 to about 20 microns. Flow features are formed (e.g., imaged and developed) in the spray-coated layer. A nozzle plate layer is applied to the spray-coated layer. The nozzle plate layer has a thickness ranging from about 5 to about 40 microns and contains nozzle holes formed therein to provide the micro-fluid ejection head structure.
