- the protection projection 68 is formed by embossing simultaneously with the formation of the support 20.
- the IC package 40 can stably support the entire lower surface thereof without being in contact with the connection terminals 46 by the center support base 20 and the protection protrusions 68 arranged on all sides thereof.
- the conical pillar-shaped protection protrusion 68 of the above embodiment can be used instead of the diagonal protection protrusion 66 in the embodiments of FIGS. 6 and 7.
- the shape and size of the portion of the opening 26 that is arranged on the side surface 24 of the support base 20 are not limited to the above-described embodiment, and can be variously changed.
- the opening 26 having a rectangular planar shape is employed, but the front and rear edges of the opening 26 are inclined at the side surface 24 and the width of the front and rear is reduced. It may be narrow.
- the terminal pieces 44 can be accommodated as in the embodiment of FIG. 5 described above, but almost the entire support surface 22 can be accommodated.
- the opening 26 may be disposed only up to the vicinity of the upper end edge of the side surface 24 as long as the opening 26 is not caught by the disposed adhesive tape 30.
- the transport band of the electronic component since the opening of the support base is opened from the support surface of the support base to a part of both side surfaces of the support base in the width direction of the band material, the support surface Even if a wide adhesive tape is used over the entire width of the opening, the side edge of the adhesive tape does not easily catch on the inner edge of the opening, and it is easy to push up the adhesive tape exposed at the opening to the same surface as the support surface and arrange it . As a result, a large area of the adhesive surface can be securely bonded to the electronic component, and the electronic component can be held well, miniaturizing the transport belt and reducing material costs, and holding the electronic component. Functions are also improved.
