摘要： This disclosure relates to a manufacturing method of a vapor chamber that includes the following steps. Form a containing space and a flow channel on a first cover. Place a second cover on the first cover, such that the first cover and the second cover together form a chamber at the containing space of the first cover and form a passage at the flow channel of the first cover. Enlarge part of the passage so as to create a circular passage portion and a flat passage portion in the passage. Insert a degassing tube into the circular passage portion of the passage. Draw gas from the chamber and fill working fluid into the chamber via the degassing tube. Seal a joint between the chamber and the flat passage portion by a resistance-welding process. Cut off parts of the first cover and the second cover that surround the passage.
