Carrier reel, carriage method using the carrier reel, and method for manufacturing electronic device

A method for mounting one of a plurality of humidity-sensitive electronic components on a printed circuit board, comprising:

• preparing a carrier reel having a hub portion, a carrier tape and a carrier package;
• storing the plurality of electronic components in the carrier tape;
• accommodating a desiccant in the hub portion;
• winding the carrier tape around the hub portion;
• putting the carrier reel with the carrier tape into the carrier package;
• sealing the carrier package;
• carrying the carrier package to an assembling line;
• after said carrying the carrier package, removing the carrier reel from the carrier package with the carrier tape;
• setting the carrier reel on the assembling line with the carrier tape wound;
• and
• mounting at least one of the electronic components on the printed circuit board by a heat treatment.
