摘要:
A composite ceramic substrate for receiving an ejection head chip for a micro-fluid ejection head and a method for making the composite ceramic substrate. The substrate includes a high temperature previously fired ceramic base having a substantially planarized first surface and at least one fluid supply slot therethrough. A low temperature co-fired ceramic (LTCC) tape layer bundle having at least two LTCC tape layers is attached to the ceramic base at an interface between the LTCC tape layer bundle and the first surface of the ceramic base. The LTCC tape layer bundle has at least one chip pocket therein and at least one of the LTCC tape layers includes a plurality of conductors.

The disclosure relates to circuits and methods for the manufacture of circuits, such as those which avoid the formation of undesirable short circuit paths. One such method maintains a layout area of a fluid composition receiving layer within a layout area of a dielectric layer. Another such method relates to the application of fluid composition receiving layers, conductive layers, and dielectric layers, such as in the provision of printed circuits.

An ink jetting structure includes a substrate that has a first surface and a second surface. A heater chip is mounted to the second surface of the substrate, and includes a first set of electrical contacts. A printhead circuit member has a third surface, a fourth surface, and an opening configured to receive the heater chip with the first set of electrical contacts of the heater chip being exposed through the opening. The third surface is mounted to the second surface of the substrate. The fourth surface has a second set of electrical contacts attached by wire bonds to the first set of electrical contacts. The third surface has a third set of electrical contacts electrically coupled to the second set of electrical contacts, and electrically connected to a flexible cable for coupling to corresponding contacts on a printer.

摘要:
This invention addresses how an end user can create an electroluminescent device (1, 31) using basic components obtained by the end user as retail items. The layers or subassemblies (15, 17) are created first. Then the layers are assembled to form a completed device customized as selected by the end user. The subassemblies may be created layer-by-layer by thermal inkjet. Elements used typically will be made by manufacturers and sold commercially separately. This encompasses the printing of conductive patterns for electroluminescence on paper. In one aspect a display has a main body that may be permanent and useful indefinitely, while a part carrying the conductive pattern defining the display is readily removed and is replaced by another such part on which a new conductive pattern is printed. For tight contact with the main body, the display provides releasable pressure. Air pockets are minimized with a thin layer of highly viscous dielectric liquid.

Micro-fluid ejection devices, methods for making micro-fluid ejection, heads, and micro-fluid ejection heads having N actuators on a first substrate and logic capable of driving the N actuators on a second substrate. The ejection heads also have less than N electrical connections between the first and second substrates.
