<p><P>PROBLEM TO BE SOLVED: To provide a storage board for storing chip-state electronic components capable of preventing or restraining occurrence of vibration when a surface cover tape is peeled off from a base board, and of preventing the chip-state electronic components from being scattered from the board. <P>SOLUTION: The storage board stores chip-state electronic components and is suitable for a high-speed chip-removing process. The storage board comprises the base board (2), with the surface cover tape (3) and a reverse cover tape (6) being thermally bonded in two striped surface areas (7, 8), each having a width of 0.5±0.15mm, on the surface of the base pasteboard, while having a plurality of chip storing transparent holes and delivery holes. The average roughness along the center line of the surface of the base board is 2.5-4.0μm, while the average peel strength (P<SB>ave</SB>) between the base board and the surface cover tape is 0.1-0.6 N, with its peel strength SN ratio [(P<SB>max</SB>-P<SB>min</SB>)/P<SB>ave</SB>] being 0.40 or lower. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
