Abstract

A jig structure for manufacturing heat dissipation unit includes a main body, which internally defines a chamber and has a top forming an upper side thereof. The top defines at least one opening, on which at least one silicon dioxide layer is provided. The chamber is in a vacuum-tight state or maintains a positive pressure inert gas atmosphere therein. The jig structure for manufacturing heat dissipation unit can be used with a laser machining tool to provide a better environment and increased flexibility for laser machining or laser welding in manufacturing a heat dissipation unit.

First claim

What is claimed is:

1. A jig structure for use in manufacturing heat dissipation units, comprising:
a main body internally defining a chamber and having a top forming an upper side thereof; the top defining at least one opening, on which at least one silicon dioxide layer is provided; and the chamber being capable of maintaining a vacuum therein, wherein the silicon dioxide layer has average 92% transmittance of light within the range of 260 nm and 1100 nm.

2. The jig structure for manufacturing heat dissipation units as claimed in claim 1 , wherein the silicon dioxide layer is quartz.

3. The jig structure for manufacturing heat dissipation units as claimed in claim 1 , wherein the main body is made of a material selected from the group consisting of an aluminum material and a stainless steel material.

4. The jig structure for manufacturing heat dissipation units as claimed in claim 1 , wherein the main body is provided with at least one passage communicable with the chamber; such that the chamber can be vacuumized or alternatively an inert gas can be introduced into the chamber via the passage.

5. The jig structure for manufacturing heat dissipation units as claimed in claim 1 , wherein the main body is formed of a first part and a second part, which are correspondingly assembled together to define the chamber; and the top being located on one side of the first part.

6. The jig structure for manufacturing heat dissipation units as claimed in claim 1 , wherein the silicon dioxide layer is provided at each of two opposite surfaces thereof with an anti-reflection film; and the silicon dioxide with the anti-reflection films having 98% to 100% transmittance of light within the range of 400 nm and 1100 nm.
