PURPOSE:To make the transit or storage of chip carrier possible without causing damages to the electronic circuit parts mounted thereon by a method wherein a chip carrier tray is provided in its surface with a recess for receiving a chip carrier therein and the recess is provided with a pair of the sloping faces opposite each other and inclined to the surface of the chip carrier tray and meeting at the bottom thereof. CONSTITUTION:When a recess 13 receives a rectangular chip carrier 12 therein, it receiver the carrier 12 with the chip carrier 13 inclined to the surface 11a of a chip carrier tray 11. Of all the faces of the chip carrier 12 in the recess 13, the two faces 12a extending upward to meet each other are out of contact with any of the faces of the recess 13. Therefore, when electronic circuit parts 15 such as semiconductor chip are mounted on these two faces 12a, such chip carrier 12 keeps the electronic circuit parts 15 out of contact with the tray 11 to avoid damages thereto, thereby permitting the transit or storage of the chip carrier 12 mounted on the tray 11. |
