A series of electronic components formed using a carrier tape. The carrier tape is adapted to enable smoothly picking up even small-sized electronic components with a suction nozzle. The carrier tape has housing holes housing electronic components therein. The housing holes are arranged in the longitudinal direction. A top tape and a bottom tape are attached to the upper and lower surfaces of the carrier tape. Interval portions between the housing holes are provided with concave slots in their lower surfaces, thereby forming air flow paths. The air flow paths form air passages which enable smoothly picking up the small-sized electronic components using a suction nozzle.

A tray module includes a first protective film, a second protective film, a cover film, and a tray. The first protective film includes a first adhesive layer. A loading target part is in contact with a bottom surface of the first adhesive layer. The second protective film includes a second adhesive layer. The loading target part is in contact with an upper surface of the second adhesive layer. The cover film is in contact with a portion of the second adhesive layer exposed by a distance (e.g., a predetermined or selectable distance) from an edge of the first protective film in a direction. Since the loading target part is fixed to the tray by the cover film instead of the protective films, contamination of the loading target part or the tray due to the first adhesive layer or the second adhesive layer may be prevented.

A light board and a carrying device thereof are provided. The light board includes a substrate and at least one support pin. The carrying device includes a plurality of carrying plates, and each carrying plate is used for carrying a light board. Every adjacent carrying plate and light board serve as a group of packaging structure. Each carrying plate is provided with a plurality of plate avoidance holes therein, and each substrate is provided with a plurality of substrate avoidance holes therein. In the group of packaging structure, at least one plate avoidance hole and at least one substrate avoidance hole are corresponding and serve as a avoidance hole group, and a support pin of a light board in a group of packaging structure located below passes through an avoidance hole group in at least one group of packaging structure located above.

A packaging for a plurality of unit medical vessels, including at least one foldable strip of unit medical vessels and a primary container defining a hermetically sealed inner volume inside the peripheral wall. The foldable strip of unit medical vessels is received in said inner volume of the primary container. The primary container has a transfer port having a closure. The closure having a closed configuration where, in the closed state of the primary container, it hermetically closes the transfer port, and an open configuration where it allows the at least one foldable strip of unit medical vessels to be transferred out of the primary container through the transfer port.

An electronic component carrier tape has an elongated shape, and includes a plurality of recessed pockets at equal or substantially equal intervals in a longitudinal direction and each accommodating a respective one of the plurality of electronic components. The electronic component carrier tape includes a flat plate-shaped core at one end portion in the longitudinal direction.
