Abstract

A heat sink vacuum packaging procedure to rapidly complete the packaging of a heat sink without drilling, pipe welding, vacuum pumping, or other processes. Because the packaging procedure saves much time and labor, the manufacturing cost of the heat sink is relatively reduced. During packaging, no welding process is employed, therefore the invention prevents accidentally flowing of tin solder into the inside of the heat sink to affect the quality of the heat sink, and the quality of the heat sink is maintained.
