摘要： A method of attaching an ink-jet printhead assembly to the headland region of an ink-jet pen cartridge to form a leak-proof seal without the use of any externally applied adhesive material. The cartridge includes a frame structure fabricated of a rigid plastic frame member formed of a first plastic material and a polymeric second material molded to the frame member. A headland region is defined at the tip of a snout region of the cartridge. An ink reservoir is connected through a standpipe defined by the rigid frame material with the headland region. The second plastic material defines a printhead assembly support structure which circumscribes a printhead and the standpipe. The printhead assembly is attached to the support structure after alignment by heatstaking the printhead assembly to the second plastic material defining the support structure. For an edge-fed printhead secured to a back surface of a flexible polymer tape, the support structure is a racetrack extending from a surface of the headland region, to which the back surface of the tape is heat staked. For a center-fed printhead die, the support structure is a pedestal surrounding the standpipe, to which the die is bonded by melting and reflowing the pedestal material.

摘要： A method of attaching an ink-jet printhead assembly to the headland region of an ink-jet pen cartridge. The cartridge includes a frame structure fabricated of a rigid plastic frame member formed of a first plastic material and a polymeric second material molded to the frame member. A headland region is defined at the tip of a snout region of the cartridge. The second plastic material forms a compliant beam at the headland region. The printhead assembly includes a dielectric layer and a printhead die. The printhead assembly is attached to the headland region after alignment by attaching the dielectric layer of the assembly to the compliant beam formed by the second plastic material. As the pen is subjected to temperature extremes, and the first plastic material expands or shrinks more than the cover layer and flexible interconnection circuit materials, the compliant beam flexes, reducing stresses which can lead to pen failures.

摘要： In one embodiment, a metal restraining element is used to reduce thermal expansion/contraction stress between a nozzle member and a print cartridge body. In a preferred embodiment, a nozzle member containing an array of orifices has a substrate, having heater elements formed thereon, affixed to a back surface of the nozzle member. The back surface of the nozzle member extends beyond the outer edges of the substrate. Ink is supplied from an ink reservoir within a print cartridge body to the orifices by a fluid channel within a barrier layer between the nozzle member and the substrate. The nozzle member is adhesively sealed with respect to the print cartridge body by forming an ink seal circumscribing the substrate, between the back surface of the nozzle member and the body. A metal restraining element, in the form of bolts or an insert, is affixed to the print cartridge body in the vicinity of the nozzle member to limit the thermal expansion of the body in a first direction when the print cartridge is heated during manufacturing or storage. This prevents delamination of the nozzle member from the barrier layer when the body and nozzle member cool after being heated.

摘要： In a preferred embodiment, a nozzle member containing an array of orifices has a substrate, having heater elements formed thereon, affixed to a back surface of the nozzle member. The back surface of the nozzle member extends beyond the outer edges of the substrate. Ink is supplied from an ink reservoir within a print cartridge body to the orifices by a fluid channel within a barrier layer between the nozzle member and the substrate. The nozzle member is adhesively sealed with respect to the print cartridge body by forming an ink seal circumscribing the substrate, between the back surface of the nozzle member and the body. The print cartridge body is formed so that the coefficient of thermal expansion (CTE) of the body in the vicinity of the nozzle member in a critical direction is within about 100 PPM/C of the CTE of the nozzle member in the critical direction to reduce thermally induced stress on the nozzle member. This prevents delamination of the nozzle member from the barrier layer when the body and nozzle member cool after being heated.
