摘要： Provided are a method for forming a wick part for a vapor chamber and a method for manufacturing the vapor chamber. The method for forming the wick part for the vapor chamber includes a base material preparation step for preparing a base material of a chamber body in which a refrigerant is accommodated, a laser installation step for setting a laser emitter on one side of the base material prepared in the base material preparation step, and a wick part processing step for processing a wick part having a predetermined size into a predetermined engraved pattern by means of a predetermined emitted laser beam by using the laser emitter installed in the laser installation step, thereby providing the advantage of being able to improve the product productivity of the vapor chamber.
