The described embodiments relate to methods and systems for forming die packages. In one exemplary embodiment, the method for forming die packages contacts interface areas of a die assembly to keep the interface areas free of an insulative material. The method distributes a flowable insulative material around portions of the die assembly.

Methods and systems of protecting substrates that are intended for use in fluidic devices are described. In accordance with one embodiment, sealant material is applied over one or more edges of at least one multi-chip module substrate that is intended for use in a fluidic device. At least one edge has an exposed electrical interconnect and the sealant material is applied over less than an entirety of the substrate and sufficiently to cover the exposed electrical interconnect. The sealant material is exposed to conditions effective to seal the one or more edges.

The described embodiments relate to methods and systems for forming and protecting electrical interconnect assemblies. In one embodiment, an electrical interconnect assembly forming method forms an electrical interconnect between one or more conductors of a first support structure and one or more conductors of a second support structure. The method also distributes a generally flowable material over the electrical interconnect and exposes the generally flowable material to conditions sufficient to render the generally flowable material into a generally non-flowable state that provides fluid protection to the electrical interconnect and supports the electrical interconnect to reduce stress concentration at the electrical interconnect.

A closed ink replenishment system for replenishing the supply of ink in negative pressure spring-bag reservoirs in a printer/plotter. A tube runs between each cartridge reservoir and an auxiliary reservoir mounted to the printer/plotter frame to form the closed ink system. As ink is depleted from the spring-bag reservoir during printing operation, the negative pressure in the cartridge increases, drawing ink through the tube from the auxiliary reservoir into the cartridge until the negative pressure decreases to an equilibrium point. As a result, the volume of ink within the spring-bag reservoir remains substantially constant so long as there is ink remaining within the auxiliary reservoir. This maintains the print quality. The auxiliary reservoir is a flat bag mounted on a spring-biased platform, which acts as a height regulating system. As ink is depleted from the auxiliary bag, the height of the platform and bag increases to maintain a constant pressure and elevation head at the spring-bag reservoir.

In a preferred embodiment, the ink reservoir in a print cartridge consists of a spring-loaded collapsible ink bag, where the spring urges the sides of the ink bag apart and thus maintains a negative pressure within the ink bag relative to ambient pressure. An ink refill system containing a supply of ink has a valve with a connector portion which is engageable with the connector portion of the print cartridge refill valve. When the valves are connected, the negative pressure within the print cartridge ink bag draws the ink from the ink refill system reservoir into the ink bag until the ink bag is substantially full. The print cartridge is then removed from the ink refill system. The mechanical coupling initially created between the two valves acts to pull the two valves closed as the print cartridge is pulled from the ink refill system. Once the two valves are closed, further pulling of the print cartridge releases the mechanical coupling, and the print cartridge may now be reused. Various external ink supply structures, having a variety of types of ink exit ports, are disclosed for use with the preferred print cartridge. In a preferred embodiment, the ink refill system contains one recharge for the print cartridge.
摘要:
An inkjet print cartridge is described which allows recharging of the ink supply in the print cartridge without removing the print cartridge from the printer. In a preferred embodiment, the ink reservoir in the print cartridge consists of a spring-loaded collapsible ink bag, where the spring urges the sides of the ink bag apart and thus maintains a negative pressure within the ink bag relative to ambient pressure. The ink bag is initially filled through a first fill port in the print cartridge. The first fill port is then sealed with a stopper. The print cartridge is installed in a slideable carriage in an inkjet printer. As the ink is depleted during use of the print cartridge, the ink bag progressively collapses and overcomes the spring force. A slideable, generally cylindrical ink valve extends through the print cartridge body and into the ink bag. The valve is open when pushed into the print cartridge body and closed when pulled away from the print cartridge body. An ink refill system containing a supply of ink is connected to the valve on the print cartridge by a flexible tube. The negative pressure within the print cartridge ink bag draws the ink from the ink refill system reservoir into the ink bag continuously or at intermittent times.
