Liquid discharge apparatus and method for producing heat sink

摘要

There is provided a liquid discharge apparatus including: driving elements; a first member including a first trace and a first IC connected to ones of the plurality of driving elements; a second member including a second trace and a second IC connected to other ones of the driving elements; and a metallic member arranged on one side with respect to the plurality of driving elements in a second direction orthogonal to the liquid discharge surface, the metallic member including: a body portion extending in the first direction while straddling over the driving elements, a first projection projected from the body portion toward the liquid discharge surface; and a second projection projected from the body portion toward the liquid discharge surface, wherein the first IC is supported by the first projection and the second IC is supported by the second projection.

主权项

1. A liquid discharge apparatus configured to discharge a liquid from a plurality of nozzles formed in a liquid discharge surface, comprising:
a plurality of driving elements; a first member which includes a first trace electrically connected to ones of the plurality of driving elements, and a first IC electrically connected to the first trace; a second member which includes a second trace electrically connected to other ones of the plurality of driving elements, different from the portion of the plurality of driving elements, and a second IC electrically connected to the second trace, and which is arranged side by side with the first member in a first direction parallel to the liquid discharge surface; and a metallic member which is arranged on one side with respect to the plurality of driving elements in a second direction orthogonal to the liquid discharge surface,
the metallic member including: a body portion extending in the first direction while straddling over the plurality of driving elements, a first projection projected from the body portion toward the liquid discharge surface, and a second projection projected from the body portion toward the liquid discharge surface, wherein the first IC is supported by the first projection and the second IC is supported by the second projection.
