Abstract

In sealing an ink reservoir manifold to a silicon die, for example, a silicon die comprising a plurality of thermal ink jet printing elements, a leak free interface is required. Furthermore, there must be no interference with the supply of ink as it flows from the reservoir to the ink jets at the interface. Typically, such interfaces utilize a screening process to apply a gasket material comprised of a room temperature-vulcanizing, silicon rubber, for example RTV@ (General Electric Co.), to seal the interface. Unfortunately, such a screening process frequently results in clogged screen patterns, requiring frequent cleaning of the screen itself. Moreover, there is no ability to control the size or shape of the gasket produced by the process without substituting different screens.

In sealing an ink reservoir manifold to a silicon die, for example, a silicon die comprising a plurality of thermal ink jet printing elements, a leak free interface is required. Furthermore, there must be no interference with the supply of ink as it flows from the reservoir to the ink jets at the interface. Typically, such interfaces utilize a screening process to apply a gasket material comprised of a room temperature-vulcanizing, silicon rubber, for example RTV@ (General Electric Co.), to seal the interface. Unfortunately, such a screening process frequently results in clogged screen patterns, requiring frequent cleaning of the screen itself. Moreover, there is no ability to control the size or shape of the gasket produced by the process without substituting different screens.

Accordingly, the present disclosure is directed toward a tool which overcomes some of the limitations inherent in the gasket screening process. As depicted in Figure 1, tool 14 deposits a uniform, rectangular-shaped bead of gasket material, 18 on the surfac...
