<p>PROBLEM TO BE SOLVED: To provide a tray which prevents dimensions of its pockets, including seats, from getting out of order due to contraction of its volume during molding and hence exhibits high dimensional accuracy, by arranging the seats on the bottoms of the pockets, whereby the seats are not connected directly to positioning sections but are separated therefrom. SOLUTION: In pockets which serve as regions for mounting semiconductor integrated circuit devices on both surfaces of a tray, support seats 6 and 8 are arranged on bottoms 13 of the respective pockets, while being separated from positioning sections 5 and 7 that regulate the transverse movement of the semiconductor integrated circuit devices during the mounting of the semiconductor integrated circuit devices. This structure provides a tray, which prevents the dimensions of the seats from going out of order, due to the contraction of the volume of the tray during the molding of the tray.</p> |
