Abstract: A MEMS chip assembly including: a support structure having a chip mounting surface; a MEMS chip mounted on the chip mounting surface, each MEMS chip having an active surface including one or more MEMS devices and a plurality of bond pads disposed alongside a connection edge of the MEMS chip; electrical connectors connected to the bond pads; and an encapsulant material covering the electrical connectors. The MEMS chip has encapsulant-retaining trenches defined in the active surface extending alongside the connection edge, each encapsulant-retaining trench being disposed between the bond pads and the MEMS devices.

Abstract: A MEMS chip assembly includes: a support structure having a chip mounting surface; a MEMS chip mounted on the chip mounting surface, the MEMS chip having an active surface including one or more rows of MEMS devices and a row of bond pads disposed alongside a connection edge of the MEMS chip and parallel with the rows of MEMS devices; electrical connectors connected to the bond pads; and an encapsulant material covering the electrical connectors. The MEMS chip has a plurality of trenches defined in the active surface, the trenches extending parallel with the rows of MEMS devices and disposed between the bond pads and the MEMS devices. The encapsulant material does not encroach past the trenches towards the MEMS devices.

Abstract: A method of printing from an inkjet nozzle device having a thermal actuator. The method includes the steps of supplying a fluid to the inkjet nozzle device, the fluid comprising an acetylenic compound; and repeatedly actuating the thermal actuator so as to eject fluid droplets from a nozzle opening of the inkjet nozzle device. The acetylenic compound is present in an amount sufficient to increase the lifetime of the inkjet nozzle device.
